May beetle (Melolontha pectoralis) belongs to the genus lamellar. Its name has gone from a month of the greatest vital activity of an insect. Despite the nice appearance, he is able to cause great damage to the forest-park area, forests and dacha plantings. Nowadays, there are many ways to deal with these insects.

May bugs

There are 3 orders of beetles: Western European, Eastern and rare. Inside this classification there are about 25 subspecies differing in large sizes. Each of the 3 species in the period of active movement is capable of destroying several hectares of young forest during the night. The flight speed of an adult individual reaches up to 3 meters per second, and the height of flight ranges up to 100 meters. Such a feature as a flight along a direct trajectory still remains a mystery to entomologists. Another characteristic part of physiology is the direction of the head at rest: north or east.

The beetle looks unremarkable: the body is oval in shape, and the color, depending on the species, can be black or red. Contrary to the laws of aerodynamics, 2 double wings attached to the chest can lift their own body weight and move it over long distances. He has three pairs of legs. There is a main organ - the antennae, which helps with the search for food. In addition, he has excellent vision. The digestive organ is the jaw. The pest beetle actively manifests itself at night, which makes it difficult to fight it.

Where dwells beetle

The May Khrushchev (its second name) can be found in any country of the world, except the territory, with permafrost. If we talk about the general habitat, then the eastern ones have chosen for themselves the high crowns of trees, while the Western European May beetles live on hills and wooded uplands. There are several subspecies living in Russia that can be found in different parts of the country, including Yakutia.

What does adult beetle feed on

The adult individual feeds exclusively on leaves of such trees as maple, linden, birch, mountain ash and practically all fruit trees and shrubs, while it does not use grass. Another feature: beetles feed not only on leaves, but also on flowers, fruit ovaries, they do not neglect needles. The preemptive time of Jora: April-May, after winter 8-month hibernation.

Maybot larva

Reproduction occurs through the laying of eggs (they look large, dirty-white), and the development - in three stages: larva, pupa, adult. An adult May Khrushchev does not live long. The female lays eggs (only underground) for 2-3 visits, in total up to 70 pieces, and at the last clutch perishes. Males die after the act of fertilization of the female. The egg-laying individual always returns to the place where she herself was born. The larva looks like a small but greasy twisted worm and is notable for its great mobility.

What feeds the larva of the May beetle

If the adult beetle is a threat to the ovary and foliage, then the larva brings much more damage, because it damages the roots. Reliable fact: during the night 1 larva can completely destroy the roots of a 2-year-old tree. According to the observations of scientists, the Maybot larva feeds on plant roots depending on the degree of development:

  • 1 year: eating the root system of herbaceous plants,
  • 2 year: devouring the roots of young trees and shrubs,
  • 3 year: the roots of adult trees go to food.

Fight against the Maybot larva

Due to the underground way of life, the fight against the larvae of the Maybolt is highly complicated. Nevertheless, there are proven methods against them. These include both the use of insecticides and folk recipes. No less effective way to destroy the larvae is sodding. To do this, plant a green manure, for example, white clover, around a tree or shrub. If we consider the natural enemies of the larvae, then these are birds, hedgehogs and some insect-parasites.

Remedies for grubs

Every year, scientists are trying to invent a "smart" drug that would destroy the larvae, but did not accumulate in the plant itself. Now there are a number of effective remedies for larvae of the May beetle, which help to fight them, depending on the type of impact on the insect's body:

  • Zemlin In addition to the Khrushchev destroys other pests living in the ground. Dosage: 50 g per 1 kg of soil.
  • Nemabact. Destroys the larvae within 1-3 days. Safe for pets and plants. The proportion of 1: 100. Watering is carried out in the morning or evening. Acts only against insect.
  • Fix it. An analogue of Zemlin, but the composition is in the form of granules. It is necessary to use when planting plants, throwing a few pellets into the ground. Act begins on the next day.
  • Aktara. Does not require special weather conditions. It is dissolved in water or mixed with the soil. You can apply at any time of the year.
  • Antihrusch. Available in suspension form. Resistant to rain and retains its protective properties for a long time.
  • Basudin. The danger is only for fish. Mix the granules with sand (3/4 liter jar). To protect the cabbage: 10 g of the mixture per 10 m2, for cabbage: 15 g per 10m2.
  • Vallar. Prepare a solution at the rate of 8 g of the drug per 1 liter of water and withstand the roots. Watering this solution is prohibited.

Folk remedies for larvae of the Maybeetle

Bringing a good result folk remedies from the larvae of the May beetle. These include:

  • Mechanical collection. Inefficient, but not expensive way. Larvae should be sought at a depth of 10-20 cm from the ground cover.
  • Planting lupine, elderberry and other representatives of the cruciferous family. Mustard sprouts and cabbage leaves are buried in the soil.
  • A solution of ammonia or ammonia and water to treat the tender roots of strawberries and strawberries.
  • Nitrogen fixers. These include white clover, peas, beans, beans. The release of nitrogen by the bacteria of the roots of these plants makes it impossible to continue the life cycle and develop the larva. In the fall, these plants can be dug up with the ground as a green fertilizer.

In order to fight with an adult insect, various light traps are used at night, lures based on sweet syrup, and collected in the morning when the Maybug is in a dormant state. In the spring you can mix the earth with chloride compounds. The characteristic smell of chlorine, like lime, does not allow the larvae who prefer oxygen to breathe.

Place of the May beetle in the kingdom of insects

The second name of the hero of today's conversation is the May Khrushchev. Coleoptera belongs to the family of platylae, the Khrushchi subfamily, of which there are more than 5.7 thousand species on the planet.

Despite its impressive appearance, this is a pest, which poses the greatest threat to deciduous and mixed forests, but also does not hesitate to cultivate fruit trees. Even more dangerous is the larva, which is popularly called horob, furrow. Depending on the habitat of the May Beetle, it gnaws the root system and destroys young forest plantations, crops, garden crops, seedlings.

The area of ​​distribution of various types of Khrushchev - Europe and Asia, wherever there are plenty of forests. In Russia, the insect is found from Arkhangelsk to Yakutsk, but prefers the center and south of the European part, Siberia.

The appearance and structure of an adult insect

Consider what a Maybug looks like after passing through a full cycle of transformation and reaching sexual maturity.

This is a large barrel-shaped insect, reaching a length of 2–3.5 cm. The recognizable color is red-brown, but depending on the species and habitat, the shades of the shell vary from brown to black. The head and pronotum are covered with light dense fibers. Hard elytra form a solid chitinous shell that protects the soft flying wings, chest, and abdomen of the imago.

The structure of the May beetle is the same as in other insects of the Coleoptera order.

  1. The head is small, semi-movably connected to the trunk. The prominent eyes of the facet type stand out well on it. They have a large angle of view, allow you to distinguish colors, perceive the slightest flicker of objects. Another remarkable detail is the lamellar mustache, similar to brushes and serving as antennas.
  2. Mouth apparatus of the May beetle is gnawing, since the adult individual feeds on the young foliage.
  3. The chest consists of 3 segments, to the second and third of them 2 pairs of wings are attached. Stiff velvety elytra have a protective function. The beetle flies with the help of a pair of tender, transparent dragonfly-like wings.
  4. A pair of legs is fastened to each pectoral segment, a total of six. They consist of segments and are completed by claws, with the help of which crinkles cling to branches of bushes and trees.
  5. The insect body ends with a belly, soft, covered with thick, dense hair.

Note! Reproduction in bruises in bruises. In size, the female cockchafer is slightly larger than the male.

The photo clearly shows the structure of the head of the crusty - faceted eyes, luxurious mustache, each of the 7 plates (the male), gnawing jaws

Features of the life cycle

Hruschi are insects with complete transformation. It is noteworthy that their life cycle is 4–5 years, of which no more than 3 months is given to the beetle itself, and the “flying” phase is even less - 30–40 days. There are 4 stages of development of the May beetle.

  • Egg. Embryo development lasts up to 1.5 months.
  • Larva. The longest period of life of Khrushchev is 3-4 years.
  • Baby doll Pupation lasts 1.5–2 months.
  • Imago Young individuals crawl out of the soil in the spring for 1-2 months, after which they die.

Consider the features of development of the May beetles at each stage of the life cycle.

4-year development scheme of the May Khrushchev

Sexual Mature (Imago)

Of the pupae, the crinkles appear, as a rule, by the end of the summer. But young imagos do not come to the surface, they winter in the soil. The basic instinct calls them to the surface in the spring of next year, when the sun warms the earth well, and young foliage blooms on the trees - the dominant food supply of the insect. May beetle comes out of the soil, in the photo below it can be clearly seen, rushes to the trees and begins to eat off after winter.

About a week later, active years begin in search of sexual partners, and after mating in females, egg-laying begins. To do this, they are several times (3-4) buried in the soil, laying a total of up to 70 eggs. Heaps of embryos, 25–30 pieces each, are located in the fertile soil layer, no deeper than 10–20 cm. This is important, since in the first year of life the hatching larva feeds only on humus.

Having fulfilled the maternal (father's) debt, Khrushchi survive to a maximum until the first days of July, after which they die.

The breeding instinct calls the lumps to the surface

Interesting! Scientists are wondering why the Maybeetle flies, if it is contrary to physical laws. It is believed that before takeoff, the insect inflates the abdomen with air, turning into something between a “helicopter” and a “dirigible”.

Larval stage

When you learn how much the Maybot lives on, you begin to understand why they consider it to be such a serious agricultural pest. The larval period lasts 3–4 years; after each season, the overcrowded hrobak molts, grows, sinks to a safe depth for wintering. This is how the life of a larva looks by years.

  1. The first season after hatching is a harmless worm. It feeds on plant residues, humus. Already by the end of September, the hrobak is preparing for winter, going deeper by 1.5–2 m. That is why it is useless to dig up the larvae during the autumn digging — you simply will not find them.
  2. In the second age, the grub larva does more harm, as her appetite increases and her jaws grow. She is already in the teeth roots of garden crops, fragile seedlings.
  3. After the second wintering, a full-fledged pest comes out, able to gnaw through the roots of plants as well as a bear. Even young saplings of shrubs and trees suffer from third instar larvae.
  4. In the fourth year (some species - on the fifth), the harmful activity of the larvae ends quickly - somewhere at the beginning of summer. She pupates.
On the C-shaped body of the grunt the larva clearly shows the head with a well-developed oral apparatus, 3 pairs of legs

Pupation

In the pupal stage, the cockchafer remains for 1-2 months. And if the larva is mobile, voracious, the pupa, on the contrary, is completely immobilized, does not feed. A distinctive feature - through the pale yellow cover looks outlines of an adult beetle - legs, abdomen, head.

Young imagos appear in August, but they do not come to the surface, and remain to spend the winter at a depth of 20 to 40 cm.

Khrushch or Western May beetle

It is a rather heat-loving species, it lives in the forest zone and forest-steppe of the European part of the continent, it does not climb north of Smolensk and the Moscow region, and east of Kursk and Voronezh also cannot be found. A distinctive feature of the insect is the black head and pronotum, light brown to red elytra. This beetle prefers to feast on deciduous plantings, does not touch coniferous plantings. Under attack are also nearby fruit crops.

Western beetle

May Eastern Khrushchka - a close fellow of the western species

Insect is found both in the European part and throughout Asia. It maintains the cold climate of the northern regions (reaches to Arkhangelsk), the Urals, Siberia, and Transbaikalia. This species of beetle can be recognized by points on the head and pronotum, which are also lighter than the western species, covered with long yellowish hairs. It is smaller in size - 20–29 mm. Favorite delicacy - young inflorescences of coniferous trees (pines, larch, spruce), for lack of those, do not shy away from leafy plantations, horticultural crops.

Maya Eastern Khrushchka gnaws young leaves

Note! The four to five year development cycle of the Maybugs manifests itself in the frequency of insect invasions. During the summer, they crawl out of the soil in clouds and literally hang in clusters on the trees. After another 4–5 years of calm, Khrushchev’s raids are repeated.

The diet of imago and larvae

By what feeds the Maybug and its voracious larva, it is possible to determine the extent of potential harmfulness.

Adult adults first of all attack oak, birch groves, gnaw the inflorescences of fruit trees (plums, cherries), damage the walnut, hazelnuts, and apple trees. In summer, any plantings - linden, alder, poplar, beech, acacia - are attacked. Coniferous plantings constitute an exception for western sandstorms, but they are preferred by the eastern variety of the insect.

What plant organs damage Maybirds? Since the years falls on May, young apical shoots, earrings of alder, birch, pine, spruce, inflorescences and ovaries of fruit and berry crops suffer the most. In addition to the favorite plums and cherries, grapes, honeysuckle, hazel, and wild rose fall into the field of view of the beetles. Invasions of Khrushchev cause great damage to nurseries, since they can gnaw and destroy the young seedlings completely.

"Clusters" of Khrushchev on maple landings

The larva is even more omnivorous - it gnaws any roots that occur along the way, be it young saplings, grassy crops, cereals, root crops, and seedlings of garden crops. Moreover, if the active period of Khrushchev does not exceed 1.5 months, then the hrabak hurts all summer.

I wonder if the cockchafer can be useful? As far as is known, only worthy fishermen appreciated the worth of the Khrushchev, or rather, its larvae. The bream, chub, ide, and perch bite perfectly on such bait. It is not difficult to dig up the larvae in the spring - they rise to the top layer of soil, hide in compost, humus.

Interesting facts about the life of the Maybug:

Cockchafer (Khrushka) - description, appearance, structure, characteristics.

May beetle is considered a fairly large insect, because the representatives of the genus reach a length of 17.5-31.5 mm. Insects have a broad and convex body of elongated oval shape, black or red-brown. The body of the May beetle, protected by chitin shell, consists of the head, chest and abdomen. The chest consists of 3 segments, abdomen - of 8.

Elytra May beetles protect the hind wings and the dorsal side of the abdomen of insects. They are distinguished by a reddish brown or yellowish-brown color. Head the beetle is small, drawn into the elytra, usually dark, sometimes may have a slight greenish tint.

May Khrushchev - an unusually hairy insect: almost all of its body is littered hairs different lengths, thicknesses and colors. Vegetation represented by hairs or hairy scales may be white, grayish, or yellow. Individuals grow hairs so often that they hide the main color.

The head of the cockchafer and pronotum are decorated with the longest, inset hairs, collected in longitudinal stripes. On elytra also elongate, single protruding hairs are located. The chest is covered with long yellowish hairs.

On the lateral surfaces from the first to the fifth abdominal segment (sternite), white specks in the form of triangles are clearly visible. Surface брюшка плотно усеяна гладкими волосками и чешуйками, а у некоторых особей отмечаются множественные или одиночные удлиненные волоски. Само брюшко состоит из 8 сегментов. На брюшке под крыльями майского жука видны маленькие отверстия – дыхальца. Именно через них воздух поступает в дыхательные трубочки, трахеи, и разносится по всем органам насекомого.

Three pairs of joints limbs May beetles also have hairs, especially long on the thighs. The first pair of legs grows from the prothorax, the second pair of extremities grows from the midrime, the third pair from the metathorax. On the legs of the front legs are two or three teeth. Middle and hind tibia slender, with slightly widened apices, on the outside with a weak transverse carina bearing spines: their apical spurs are normal, narrow. Paws of a cockchafer no longer than the legs, bottom with short setae. Claws rather strong, arcuately curved, from the bottom near the base with a sharp prong, directed slightly backwards.

Bulging eyes May beetles have a complex structure and a good viewing angle. Each compound eye consists of several thousand simple eyes.

Antennae May beetle, represented by one pair and performing the olfactory function, consist of 10 segments, the third of them is elongated. The last flagellates of the antennae of males are significantly curved and represent a mace - seven identical plates, similar to a fan. In females, the mace is six-plate and smaller.

Oral apparatus May beetle gnawing type, thanks to him, the insect is easily cracked down on the shoots of plants. Along the edges of the mouth of the cockchafer are 3 pairs of oral appendages. The first pair is a mandible (the upper jaw of an insect). The second pair is the lower jaws, on each of which one palp grows. The third pair has grown together and forms the so-called lower lip, from which the palpi, the tactile organs of the insect also depart. A small plate, upper lip, covers the movable oral appendages from above. When eating food, the beetle uses mainly the upper, but also the lower jaws, and with palpi it moves the food closer to the mouth.

Chitin shield May beetles are large, smooth, glossy, different in semi-oval shape. There are short hairlike scales on the shield and sometimes a dotted pattern is noticeable.

Chitinovy ​​ledge on the end of the abdomen (pygidium) is an elongated process of a triangular or blunt shape, oblique or plumb. The pygidium of males is well developed, in females it is much less pronounced.

What feeds the May beetle and its larva?

The basis of the diet of the adult may-beetle consists of young shoots, leaves, flowers and ovaries of cultivated and wild-growing trees and shrubs. The favorite fruit plantations of insects are apple, cherry, sweet cherry, plum, sea buckthorn, gooseberry and black currant. May beetles are happy to eat the leaves of maple, oak, rowan, poplar, birch, chestnut, willow, aspen, hazel, beech, linden.

The larvae of the cockchafer, growing in the ground, are very voracious and cause more serious harm than adult insects. In the first year of life they are quite harmless, content with humus and rhizomes of herbs. But after a year, the Maybot larva begins to feed on the roots of young trees, fruit and berry crops. A special delicacy for the larvae are the roots of root crops: carrots, beets, onions, potatoes, as well as corn and strawberries, the roots of young conifers, especially pines and larch.

Types of May beetles, photos and names.

According to the classification given on the website globalspecies.org, today 63 species of May beetles are known. Below is a description of some varieties.

  • May Eastern Khrushch the same eastern beetle or wild chestnut (lat Melolontha hippocastani) - a representative of the genus, characterized by pronounced sexual dimorphism. Males are smaller than females, the size of the May beetle is about 20.5-29 mm in length, width is 10.6-14.6 mm. Color variability is characteristic of these beetles, but the dominant color is brownish with a red tint. The insect differs from the western May beetle with black antennae, legs and pygidium. The small head of the May beetle, drawn into the pronotum, is densely covered with many bright dotted points and is dotted with long yellowish-gray hairs. The pygidium of the male beetle is thin, but ends with a thickening in the form of a button. In females it is short, not narrowed and less than in the western May beetle. The larvae and pupae of the eastern and western May beetles are very similar. The Eastern Maybug eats shoots of coniferous trees such as pine and larch, and also feeds on foliage of hazel, birch, oak, maple, chestnut, aspen, poplar and willow. The insect is quite numerous in Europe and Asia: the eastern May beetle (Khrushka) lives in the northern part of the European steppes, in the Siberian taiga and forest-steppes, and in Northern and Central Europe prefers forest clearings on dry sandy landscapes. In the north, the habitat of the Maypole encompasses Vyborg, Arkhangelsk and Tartu, the eastern border begins in Yakutia, goes along the Pacific coast through northeast China to Beijing. In the south, the species range limits the Danube River, then the border goes through Odessa to Zaporozhye, Uralsk and through the Altai Mountains to Shanghai. The flight of insects of the northern population begins in mid-May and lasts until the end of June. May beetles living in the south begin to fly at the end of April and continue until the beginning of June. The flight of the inhabitants of the taiga occurs from late spring to early July. The May Eastern Khrushka forms 2 subspecies:
    • Melolontha hippocastani romana - a variety of insects from Central Italy, their distinguishing feature is a multitude of white hair-like scales, densely covering the body,
    • Melolontha hippocastani mongolica - inhabitant of Eastern Siberia, Transbaikalia, Northern Mongolia and Northern China. Insects are characterized by a particularly stocky build and a short, thick tip of a pygidium.

  • May Chrushche west, the same western beetle (latMelolonthamelolontha) - an insect with a wide, strongly convex body with a length of 22.5-31.5 mm and a width of 11.2-15 mm. Western Khrushka is longer than the eastern one. In addition, in contrast to the eastern May beetle, the western pygidium is more gentle, it gradually and gradually narrows towards the end. The third difference is that the flight of the Western beetles begins 10-12 days later, moreover, they are lighter and more thermophilic and prefer to settle in the fields. The head, abdomen and pronotum of the western May beetle are black in color. Elytra, extremities, and antennae are light brown, reddish brown, or nearly black. Within the species there is a pronounced color variability, represented by many different variations. The western May beetle feeds on foliage of beech, maple, elm, hazel, poplar, willow and walnut, especially prefers young oak leaves and plum leaves. In contrast to the eastern May beetle, the western habitat is more shifted to the south. Insect lives almost throughout Europe. The southern boundary of the range passes through Zaporizhia, Kirovograd, the northern part of the Odessa region to the lower reaches of the Dniester. The northern border line extends from the south of Sweden to the north of the Moscow region. The eastern boundary of the Maybeetle habitats begins from Estonia and passes through Smolensk, Kursk, Voronezh and Kharkov. In the south, the flight of May beetles lasts from the end of April to the beginning of summer, the northern populations begin to fly in mid-May and disappear in late June.

  • Caucasian May Khrushch (lat Melolontha pectoralis) - a rare species of May beetles, an endemic species that lives exclusively in the southwestern part of Germany and Austria. The length of the May beetle is 21-29 mm, width - 10-14 mm. A distinctive feature of this cockchafer is a shorter, rounded-shaped pygidium. In addition to the adjacent hairs, the pygidium also has longer protruding hairs. This beetle differs from Melolontha melolontha by its larger mace. The third segment of the antenna is anteriorly behind the middle with a short and blunt clove. 4th antennal segment of females more transverse, anteriorly elongated and somewhat longer than the western crusty, dull toothlike process. The pronotum in the middle of the disk is covered with rather thick, and on the sides very dense small points. Its hair is thicker and longer, including on the sides, so the 2 longitudinal strips of condensed hairs are less noticeable than the western May beetle. Often the whitish scales on the sheaths almost completely hide their main color.

  • March Khrushchev (lat Melolonthaafflicta) has a not too elongated, but rather wide body with rounded sides. The body length of the March Khrushchev is 18.5–23.5 mm, width is 10.5–13.5 mm. Pigidium in males triangular, obtuse, without a process. In females, it is wider than in males. The head and pronotum of this species of the May beetle are covered with thick hair-like scales. Between them grow long hairs. In the middle of the pronotum disk there are 2 bare, shining strips covered with sparse points. At the anterior margin, they converge together, but back a little apart, and the posterior edge of the strip does not reach the middle of the pronotum. The front panel is punctured and covered with rather thick white-yellow hairy scales. On the rear edge is bare and smooth. Yellow-white scales on elytra hide the main background. The color of the beetles of the March beetle is yellow-brown with a black lateral edge. The body of the beetle is black with a bronze tint. The thighs and legs are black-brown, the legs are red-brown, the palpi and small stalk of the antenna are red-brown, the mace is black-brown. The March beetle is widespread in the east of Uzbekistan, where the cities of Samarkand, Tashkent, Margilan (M. afflicta afflicta type) are located, and in the west of Tajikistan, where the Gissar Range (M. afflicta hissarica) is located.

  • Melolonthakraatzi - type of the May beetle, which has a smaller and slimmer body than that of the Western Khrushchev. The size of the insect is 24.5-28 mm in length and from 11.5 to 13.5 mm in width. The third segment of the antennae is thinner, less thickened towards the apex, anteriorly in the apical half without tubercles. The pronotum is covered with shorter, almost adjacent hairs. Pygidium is somewhat more steep, with a shorter top. Variants of colors of this May beetle are different. In a typical species, the body is black, the hairs do not hide the main background. The tibiae, paws, palpi, and antennae are red-yellow, the elytra brownish-yellow with a narrowly blackened base. In the second species (Melolontha kraatzi brenskei) the body is black, pronotum, shield and elytra brown, antennae, legs and paws red-yellow. The third type of insect can be completely black, and only the palpi and antennae are red-yellow in color (Melolontha kraatzi persica). May beetle lives in the south-east of Azerbaijan, it is distributed in northern Iran - along the southern coast of the Caspian Sea to the east to the city of Gorgan.

Reproduction and development of the May beetle (Khrushchev). Life cycle.

For the May beetle is characterized by development with complete transformation. The life cycle lasts from 3 to 5 years and consists of the following phases:

  • The egg stage lasts 30-40 days,
  • The pupa stage lasts 30-60 days,
  • In the larvae stage, beetles stay about 3, less often 4 years,
  • In the stage of imago (adult), the Maybug lives for about a year.

The breeding season of the Maybugs falls at the end of May - the beginning of June. After mating, the female digs into the ground and lays 20-30 eggs. Then she again intensively feeds, mates, digs the soil and makes another laying. Each female lays eggs 3-4 times, after which she dies. The total number of eggs is 50-60, rarely 70 pieces. The depth of the laying reaches 20-30 cm. The eggs of the May beetle are gray-white in color, with a diameter of 1.5 to 2.5 mm.

After 30-40 days, the larvae of the May beetle hatch from the eggs. The larvae, or furrows, have a thick, curved, white torso with three pairs of limbs and a large rounded head of yellow or brick color. On the head of the larva are strong and strong mandibles (upper jaws of the mouth apparatus). The body of the Maybot larvae is covered with sparse hairs. For the next 3 years, the May Khrushcha larva develops and winters in the ground. For wintering, it digs into the ground approximately to a depth of 1-1.5 meters, and in spring, approximately in April, it rises higher to the upper layers of the soil. The first year of life, it feeds on humus and tender grass roots, and on the second summer, it begins to eat thicker plant roots. During feeding during the day, the larva can creep up to 30 cm. In autumn (approximately in October) the larva of the May beetle migrates again to the lower layers of the soil for the next winter.

In the southern regions after the third wintering (in the northern after the fourth), in the middle of summer, approximately in the end of July - the beginning of August, pupation occurs. The larva of the May beetle, at this point having a length of 45-65 mm, digs deeper into the ground and turns into a pupa. The baby beetle pupa resides in a special chamber, a pupal crib, and it already looks very similar to an adult. And yet, unlike imago, it has a yellowish color, short and poorly developed wings, and also a tucked head down. The pupa size is 25 mm in length and about 18 mm in width. The pupal phase lasts 30-45 days. Then, while still under the ground, the Maybeetle crawls out of the pupa, which continues to be in the crib.

The last wintering insect is in the soil. May beetles fly out of the soil at the end of April (eastern) - early May (western): they pierce a tunnel in the ground and get out. Eastern May beetles fly out of their underground shelter 10-15 days earlier than western ones. Females are selected from the dungeon for 7-10 days later males. During this period, beetles are intensively engaged in the search for food, eat leaves, buds, shoots of trees and bushes, which cause significant damage to forests and agricultural plantings.

Enemies May beetles.

The natural enemies of the Maybirds are animals and birds that feed on these insects and their larvae. In the forests, these can be vertebrates such as badgers, hedgehogs and moles. In the fields, when loosening the soil and carrying out other agrotechnical measures, the larvae appear on the surface of the earth and, naturally, can be eaten by bats and birds (rooks, starlings, etc.).

Fight against the May beetle.

May beetle at all stages of its existence is one of the most dangerous pests. Adult insects during massive flight significantly damage vegetation, eat leaflets and young shoots. Harm is inflicted not only by the May beetles, but also by their voracious larvae, which gnaw up or completely eat up the young roots of plants, which leads to drying out and death of entire plantations. Therefore, only complex measures aimed at the destruction of larvae and adults can become effective methods of struggle. Various insecticidal preparations are considered to be the most common chemical means of fighting the May beetle:

  • Basudin - a combined remedy for the contact, internal and translaminar lesion beetle, begins to act immediately after tillage, effectively for 6 weeks,
  • Antihrusch - highly effective means of contact-systemic action with a low level of toxicity. Suitable for embedding into the soil, soaking the root system of plants before planting and for spraying plants during the period of the flight of pests,
  • Zemlin - a remedy for contact-intestinal Maybugs, which is introduced into the ground with planting material, and is also used during the growing season,
  • Fix it - contact preparation for soil application, which creates plant protection for 6 weeks,
  • Effective bioinsecticide is especially popular with gardeners. Nemabact, which consists of entomopathogenic nematodes and symbiotic bacteria used to protect and heal the earth. The nematode, which looks like a microscopic worm, penetrates into the larva of the May beetle through the respiratory tract and within a day destroys it from the inside. Nemabak is a completely biological drug, effective and absolutely safe for people, pets and wild birds.

Also in the fight with the grubs of the Maybolt help timeless, time-tested folk methods:

  • deep digging of the land and collecting the larvae by hand,
  • digging in the autumn with the introduction of whiteness or chlorine into the soil,
  • spring watering of beds with strawberries and other plants diluted with liquid ammonia (10-20 ml per bucket of water),
  • cultivating the ground and foliage of fruit and ornamental shrubs with an infusion of onion peel (100 g dry weight for 5 days in a bucket of water),
  • planting near fruit trees and shrubs white creeping clover, the roots of which are able to accumulate nitrogen, repelling insects.

Shaking off the branches and hand collecting Maybirds is a long and laborious process, so it is better to make special traps. Cut plastic bottles or cups are filled with sweet water with honey or jam and are hung in the trees. The night trap is made of any wide container smeared from the inside with a sticky compound, and a light source is determined in the center, for example, with solar batteries. At night, a light trap for Maybugs is installed under the trees.

Ранней весной не помешает разместить в саду скворечники: скворцы, дрозды, грачи и прочие пернатые будут с удовольствием лакомиться взрослыми майскими хрущами и кормить личинками своих птенцов. Ежи и кроты тоже не прочь угоститься жирными личинками майского жука, поэтому не следует закапывать кротовые норы и отпугивать с огорода ежей.

May beetles do not tolerate the smell of elderberries, lupins and some cruciferous plants (cabbage, turnips), so with the threat of mass pests do not neglect the planting of these plants.

Habitat and species

In the natural environment May beetles can be found in many countries. They live in Europe, Small and Central Asia, Northern Iran, China, Japan, India, Russia, Tibet, the United States, Syria, as well as in Ukraine, the Caucasus, the Philippines and the Indochina Peninsula. Many species of this insect inhabit the Indo-Malay region, namely South and Southeast Asia, and on many islands located in the Pacific Ocean, between Australia and Asia.

To date, according to the official classification of the May Khrushchev, 63 species of these insects are known. Among them, in Russia and the CIS countries, only 9 species of May beetles inhabit:

  1. Melolontha aceris.
  2. Melolontha afflicta or March Khrushchev.
  3. Melolontha clypeata.
  4. Melolontha gussakovski.
  5. Melolontha permira.
  6. Caucasian May Khrushka (Melolontha pectoralis).
  7. May Khrushchea western (Melolontha melolontha).
  8. Melolontha kraatzi, there are two types of brenske and persica. Differ from each other color.
  9. May Eastern Khrushchev (lat. Melolontha hippocastan), he is wild chestnut Khrushka or Eastern beetle.

Appearance and body structure

Chafer - a rather large insect, representatives of this genus can reach from 17.5 to 32 millimeters in length (dimensions primarily depend on the floor of the hruscha). These beetles have a convex and wide body of oval shape, red-brown or black color.

Khrushch is an amazingly hairy creature, almost all its body is covered with hairs that differ from each other in color, length and thickness. Thin hairs or hairy scales may be yellow, gray or even white. Some individuals can boast of dense vegetation that covers the main color of the insect.

On head and pronotumka are the longest and indented hairs, collected in longitudinal strips. Elytrae adorn single sticking, elongated hairs. The chest is covered with long, yellowish vegetation.

On the abdomen, you can see dense hair of scales and smooth hairs, and some individuals have single or multiple elongated hairs. On the side surface from the first to the fifth abdominal section are white triangular specks.

The body of Khrushchev protects chitin shell. It consists of the head, thoracic and abdomen. The abdomen is divided into eight segments, and the chest is only three.

The back and back wings of a beetle are protected by rigid elytra. They are painted in reddish-brown or yellowish-brown shades. The head of this insect is retracted into the elytra, it is small and may have a metallic greenish tint, but is usually painted in darker colors.

We will analyze the external structure of this beetle more closely., in this picture we can see all the parts of the body of this insect:

  1. Head.
  2. Mouth apparatus.
  3. Antennae.
  4. Difficult eye.
  5. Prothorax.
  6. The middle chest.
  7. Posterior chest.
  8. Elytra.
  9. Wing.
  10. Eight abdomen segments.
  11. Upper leg segment.
  12. Middle segment of the leg.
  13. Lower segment of the leg.

As we can see, the belly of the insect consists of eight segments-segments. On the abdomen, right under the wings are small holes - spiracles. This is the beetle's respiratory organ, through it air enters the trachea through special tubes, and then is carried to all organs.

Khrushchev has six jointed limbs., they grow in pairs, parallel to each other. The first pair of legs is located on the prothorax, the second - on the midrime, the third pair is on the subthorax, respectively. Two or three teeth can be seen on the legs of the front paws. Middle and hind paws rather thin, with weakly widened tops of the legs and with a weak transverse carina, on which the spines are located. The parts of the legs, on which there is an emphasis when walking, are no longer than the legs, covered by short stubble from below. The claws are strong, arcuate-curved, their bases crowned with sharp teeth, directed back.

The bulging eyes of a beetle are distinguished by a very complex structure. Each complex organ of vision consists of several thousand small simple ocelli. Thanks to this feature, the insect has a good viewing angle.

This beetle has one pair of antennae.consisting of ten segments (third slightly elongated). They perform an olfactory function. The male mustache is curved, and their ends resemble a fan consisting of seven identical plates. The females have a six-plate fan and more modest size.

The oral apparatus of these insects is of the gnawing type. Thanks to this organ, beetles easily deal with shoots of any plants. At the edges of the mouth are three pairs of oral appendages:

  1. The first pair is a mandible. This is the upper jaw of the gruel.
  2. The second pair - the lower jaw. On each of the jaws there is one palp.
  3. The third pair is accrete, it serves as the lower lip. The palpi - the tactile organs of the beetle depart from it.

The upper lip looks like a small plate, it covers the movable oral appendages. With the help of palpi insect attracts food to the mouth, and then eats it, using the upper jaw. Mandibles are not always involved in this process.

Protective chitinous shield has a semi-oval shape, it is large and smooth, glossy. This shield is covered with short hairy scales, which often form a dotted pattern.

At the end of the abdomen of the beetle is a chitinous protrusion. It is called pygidium and is an elongated, triangular or dulled process. Pygidium can be steep or sloping. In females, this protrusion is much less pronounced than in males.

Stages of insect development

May beetles are characterized by full development.. Their life expectancy is from three to five years and consists of the following stages-phases:

  • Egg stage - lasts from 30 to 40 days.
  • In the larva stage, the insect remains for about three years, in rare cases - four.
  • The pupal stage is an average duration of 30-60 days.
  • In the stage of imago, that is, as an adult, the May lump lives about one year.

The reproduction period of these insects falls on the end of May - the beginning of June. The total number of eggs in one clutch is usually from fifty to sixty pieces, in rare cases - seventy pieces.

Diet of may beetles

The main diet of adult Khrushchev includes young leaves and shoots, ovaries and inflorescences of wild and cultivated shrubs and trees. Such fruit plantations as apples, cherries, cherries, plums, mountain ash, sea buckthorn, black currant and gooseberry are especially appealing to beetles. They also enjoy eating oak, birch, maple, poplar, willow, hazel, chestnut, linden, aspen and beech leaves.

Some fans of unusual pets often contain these insects at home. With such preferences in food, feeding them does not cause any particular difficulties.

Beetle larvaehiding in the soil, terribly voracious and cause serious damage to garden plantings. In the first year of their life, they are completely harmless, as they feed on grass roots and humus from the soil. But about a year later, the larvae switch to the root systems of young trees, berry and fruit crops. They have a particular passion for root vegetables such as carrots, onions, potatoes and beets. And also they will not give up strawberries, corn and the roots of young conifers, especially larch and pine.

Useful properties of Khrushchev

In spite of the significant damage that the grubs bring to their larvae, adult beetles, as it turned out, have useful and even healing properties. Traditional medicine recommends using these insects in some of their recipes. Many people are familiar with the particularly popular methods of treatment through May shrivels.

With the help of these insects You can cope with various kinds of injuries, including complex suppurations, as well as cure sciatica, impotence, scrofula, and even diseases such as uterine cancer and pulmonary tuberculosis.

However, as with other drugs, similar treatments should be treated with great seriousness and caution. First of all, you first need to consult with a good doctor.

Interesting Facts

In conclusion, we bring to your attention A list of interesting facts about these insects:

  1. According to scientists, such beetles should not fly at all, since they have too small lift coefficient.
  2. In the third year of life, one larva of the Khrushcha is capable of destroying the root system of a two-year-old pine tree within a day.
  3. In the fairy tale of Hans Christian Andersen "Thumbelina" it was such a beetle who acted as a contender for the title of the bridegroom of the main character.

Cockchafer (Khrushka): description, structure, characteristics. What does a beetle look like?

The May beetle is an arthropod insect and belongs to the order of beetles, the family of platinfreet, the genus of May beetles.

As for insects, the cockchafer is very large, some individuals reach 17.5-31.5 mm long. Trunk body broad and convex elongated oval shape, with black or red-brown color. Also, the body of the May beetle is under the protection of chitinous shell, it consists of the head, chest and abdomen. In turn, the insect's chest consists of three segments, and the belly of eight.

May beetle wings are protected by posterior elytra of reddish-brown or yellow-brown color. The head of the beetle is small and drawn into the elytra, it has a dark color, although there are beetles with a greenish tinge on the head.

And the may beetle is a very hairy creature, it is almost completely littered with hairs of different length, thickness and color. Usually, the hair of a cockchafer is white, yellow, or gray, and, interestingly, some beetles may have so thick vegetation that they even hide the main color.

The longest hairs collected in longitudinal strips adorn the head of the May beetle. Elytra has long, single, sticking out hairs, while the chest is covered with yellow hairs.

The abdomen of the May beetle, consisting of eight segments, also has small holes, the spiracles, which play an important role in the life of the insect, it is through them that the air enters the breathing tubes, the trachea and spreads throughout the entire body of the beetle.

In May beetle in the presence of three pairs of joints, which also have hairs, especially long on the thighs. The first pair of legs of the beetle comes from the front breast, the second pair from the mid-breast, and the third from the rear breast. On the legs of the front legs there are 2-3 teeth.

Eyes of the May beetle are convex in shape, they have a complex structure (each compound eye consists of several thousand simple eyes), and allows you to see under a wide viewing angle.

The antennae of the cockchafer have an olfactory function important for the insect, they consist of ten segments, the third segment being the longest. Flagella in antennae strongly curved, in general, they somehow resemble a mace or fan. In males, this “mace” is more curved and has a larger size than in females.

As for the oral apparatus, it is of the gnawing type of May beetles, so that they easily eat the shoots of plants. At the edges of the mouth are three pairs of oral appendages: the first is the sting, the second - the lower jaw, and the third forms the lower lip. The upper lip, which is a small plate, covers the movable oral appendages from above. While eating, the beetle uses both lower and upper jaws, and palpi moves food closer to the mouth.

The chitinous shield of the May beetle has a semi-oval shape, it is large, smooth and glossy.

Lifestyle of the Maybeetle

In spring, when green leaves begin to bloom in the trees, the May beetle males appear. After 7-10 days, the females join them. Many species of May beetles are especially active at night and in the evening. Some Khrushchi actively fly in the morning before dawn, sometimes they are attracted by artificial sources of illumination. But in the afternoon, especially after eating, the beetles, on the contrary, slow down their activity.

During its short terrestrial life in 30-40 days, the Maybug, however, is actively flying, so in search of food for the day it can fly up to 20 km, developing a speed of 8-11 km per hour. During the flight, the Khrushchi buzzed heavily, and it was this particular feature that the great Ukrainian poet T. Shevchenko noticed.

May Western Hrusch

Also known as Western Maybug. In size it is longer than the eastern relative, with a strongly convex body. They are almost the same size, but differ in some habits, details of appearance, so the spring Khrushchev appears 10 days later than the eastern one in the spring, it is more thermophilic, likes to settle in the fields. The antennae are not black, but light brown or reddish-brown. It lives in many European countries. In Ukraine, many beetles of this species live in the Odessa and Kherson regions, in the lower reaches of the Dniester.

Caucasian May Khrushch

It is a representative of a rare species of May beetles. Currently lives exclusively on the territory of the south-western part of Germany and Austria. It differs from other species by a short pygidium of a more rounded shape. They also have whitish scales on the elytra, which sometimes almost completely hide their primary color.

Features of the May Beetle

He is considered one of the first heralds of spring. With the arrival of heat, the worm is waking up after hibernation and goes in search of food. The insect flies very quickly, at a speed of two to three meters per second. Khrushch is able to overcome about twenty kilometers per day. At first it rises up to a height of 5 to 100 meters, then, circling above the ground several times, flies further in a straight line. Interestingly, according to the laws of aerodynamics, this insect should not fly because of too low a lift coefficient.

Hruschi always fly in a certain direction. It is impossible to knock them off course. In this regard, scientists even conducted some interesting experiments. Having caught an insect, it was released in a different place, after which the May beetle still returned to the previously chosen route.

These insects are able to navigate the terrain and the sun. During the flight, the beetle remembers bright objects that serve as a guide. In addition, these insects are influenced by magnetic fields.

The rhythm of the life of a beetle is determined by the sun. During the day, the insect sits on a tree, barely moving, and it becomes more active in the evening. The life of the May beetle is mainly nightlife, it is at this time of day that it feeds and flies.

Appearance of the beetle

There are 24 species of these insects. Probably, there is no such person who would not know what the Maybug looks like. The least damage to plants is from representatives of the Caucasian and Eastern species. Beetles of the western species are most annoying to gardeners and gardeners.

The Western Khrushchev is a brown-yellow color, with a black chest, a red back and legs, has a mustache with a brown mace. Insect length - from 25 to 35 millimeters. The larva of the cockchafer is more often of white and yellow color, fleshy, folded, has a dark head with two pinching fangs. Egg beetle - oval, white. The male can be distinguished from the female by the appearance of the back of the abdomen. In male May beetles, it has the appearance of a long triangular process, which in the female is much shorter. The body of the beetle is covered with chitinous shell.

The structure of the head Khrushchev

On the head of the beetle there is an oral opening with the upper lip, having the form of a transverse plate. The lower jaws and the lower lip have palps, which are the senses.

On both sides of the head are the eyes. The structure of the organ of vision is complex: it consists of a huge number of simple ocelli. Antennae with beetle plates are the olfactory organ, with their help the ragweed finds food. The male has a strongly curved "mace" at the end of the antennae. The head of the insect is not able to turn from side to side.

Thoracic department

The breast is divided into three parts. Each of them carries a pair of legs. There are six beetles in total. The middle and back of the thoracic are also wings.

The belly of the insect is covered with hard elytra. They are necessary for the protection of the membranous hind wings and the dorsal side of the abdomen abdomen. During takeoff, the elytra are lifted and retracted to the sides, then the wings of the May Beetle are straightened.

The internal structure of the May beetle. Digestive system

With the help of the pointed ends of the upper jaws, the beetle bites off a piece of leaf, and it crushes it with its lower jaws. Further, the food moves along the esophagus to the stomach, in which with the help of chitinous teeth it is chafing. Once in the intestine, food is digested, absorption of nutrients occurs.

Circulatory system

Like the other arthropods, this insect has an unclosed circulatory system. With the blood flowing in the body cavity, the internal organs and tissues receive nutrients. The movement of blood provides the heart, which pulses and drives it to the head end of the body. Reverse its current is impossible due to heart valves. When the heart expands, blood from the back of the body enters. The lateral openings of the central organ of the circulatory system have valves that prevent the backflow of blood. In the respiratory process, this biological fluid is not involved.

The structure of the excretory system

Мальпигиевы сосуды, что расположены в полости тела, составляют выделительную систему насекомого. Они имеют вид тонких трубочек, собранных в пучок, замкнутых сверху и основаниями открытых в кишечник. При помощи мальпигиевых сосудов происходит фильтрация продуктов обмена, которые становятся кристаллами. Проходя сквозь кишечник, они вместе с непереваренными остатками пищи выводятся из организма.

Органы размножения

Самка насекомого имеет два яичника, в них образуются яйца. The output of their mature forms occurs through the unpaired oviduct.

Male spermatozoa enter the seminal receptacle. The male beetle has a pair of testes, which pass into the seed canals, further uniting into the unpaired ejaculatory canal through which the sperm is released.

Limbs

On the chest of the beetle there are three pairs of walking legs, consisting of their movable segments. The limbs are covered with hairs, at the end of them there are claws, clinging to them, the beetle easily moves along the bark and foliage of the trees.

The shape of the front legs is like a scraper, which helps the beetle to dig a hole by laying eggs.

How the Maybug breeds. Stages of development

The female beetle may breed 2-3 weeks after it leaves the pupa. Mating, she buries herself in the ground, where she lays eggs. After that, she again goes in search of a male, and the process of laying eggs is repeated. The whole action can occur up to four times, after which the female dies.

The eggs laid by the female are off-white. Their width is 0.2 cm, length - 0.3 cm. At first, the eggs are soft, then they harden. Their development occurs from 24 to 50 days.

It is thick and curved, has a light color. The larva of the cockchafer has a round head, light yellow or brown and three pairs of paws. It can reach 65 mm in length.

The pupa is yellowish, usually in the ground, in a “crib”, similar in appearance to the adult beetle, but its wings are shorter. The pupa length reaches 0.25 cm. This developmental phase lasts from two to four weeks.

What eats Khrushka

In spring, when the air warms up to a temperature of + 10 ° C and higher, the cockchafer flies. Insect causes great harm to fruit trees, damaging the leaves, flowers, ovaries. Apple trees, plum, cherry, and walnut suffer more than other trees. In addition, the May beetle can eat the needles and foliage of various shrubs. He does not eat only the leaves of lilac and ash. Having destroyed the foliage in one area, the beetle flies to another.

The larvae damage the roots, stems of plants, vegetables.

Features and habitat

May beetles inhabit in Europe and Asia, preferring to populate zones of forest-steppe and forests, but having in close access flowering fruit and berry trees or shrubs.

There are two independent kind of- east Chafer and western may beetle. Although they are very similar both in appearance and in lifestyle, the eastern beetle prefers to settle under the forest canopy in a cool shade, while the western one, more warm and light-loving, inhabits more and more open fields.

Both of these species can occur in the same territory. However, the east is able to survive in more severe and cold conditions.

Therefore, it is distributed up to Arkhangelsk in the north and to Yakutsk in the east. Western May beetles never rise above Smolensk.

Character and way of life of the May Beetle

May beetles for the most part adherent strict schedule. Each more or less homogeneous population has its own years of mass summer, which are rarely changed by the crane.

For example, the Rex aberration beetles are performed once every 5 years, and Nigripes once every 4 years. This does not mean that between these years these beetles cannot be met.

Each year, a certain number of beetles of each species flies out. But it is precisely mass flights that take place according to a schedule strictly defined for each type.

From the very beginning of their birth, being a larva, until the very end of their lives, the May beetles are busy searching for food and its absorption.

As soon as they appear out of the ground, they either immediately fly into flight, breaking into the crowns of fresh green leaves, young shoots and begin to absorb everything that is suitable for this purpose systematically and quickly.

Thus, the May beetles have long been a real disaster for agriculture, eating and spoiling most of the crop.

In 1968, about 30 thousand centners of May beetles were caught and destroyed in Saxony. Counting on average weight, we can conclude that about 15 million beetles were then exterminated.

In the modern world, an increase in the number of beetles to such a population could have led to a real catastrophe both in the agro-industrial and in the economic sphere.

There are many ways how to deal with the Maybug. Previously, the most successful results were brought by spraying the fields and adjacent areas with pesticides.

But because of the danger that this method carries for people, it had to be abandoned. Many gardeners manually collect adult beetles on their plots, and destroy the larvae during weeding and digging the soil.

But the most promising method is the sterilization of male Maybugs with ionizing radiation.

This method allows to reduce the number of the next generation of beetles by 75 - 100%. But, unfortunately, this method has not yet been studied completely and cannot be applied everywhere at this stage of development.

Nutrition May beetle

You have already understood that the Maybeetle is a frantic pest of gardens and fields. But what exactly does he eat?

From the moment of birth, the grub beetle feeds on plant roots. In the first year of life, just thin larvae, such as the roots of lawn grass, go to the larvae that have appeared in food.

With each subsequent year of life, the jaws of the insect are strengthened, which allows you to expand the diet.

Over time, the Maybot larvae eat the roots of potatoes, strawberries, corn, fruit and even conifers.

As a result, the plants slowly wither and die. An adult individual feeds on buds, fresh green leaves, flowers of trees and shrubs.

Reproduction and longevity

After mating, the male dies, and the fertilized female of the May beetle digs into the ground to a depth of about 30 cm and lays from 50 to 70 eggs.

Pupae of the Maybug

After about one and a half - two months, the larvae hatch from the eggs, which live in the soil for 3 to 5 years.

During the periods from spring to autumn, the larvae climb closer to the surface of the earth for food, and with the onset of cold weather they descend back to wintering grounds.

By the end of its development, after passing through several molts, the larva for the last time descends into the ground for wintering and moves on to the next step of development, the pupa.

The pupa in its shape already resembles an adult beetle, but only in white. She is not able to move or grow, but already has short wings.

By the end of the summer, the pupae are finally transformed into adult individuals of the May beetle - they develop a strong chitinous shell, organs of hearing and vision, legs and wings.

However, out of the ground, independent adults are selected only in the spring, because of which, in fact, these beetles got their name.

The appearance of the May beetle in the garden threatens either the destruction of the crop, or a very big hassle with cleaning the larvae and beetles.

But the help of summer residents in this difficult work can come from a completely unexpected side. In addition to natural enemies, such as rooks, jackdaws, magpies, jays and other birds, common beetles are eaten by ordinary yard dogs and cats.

Your pets with great joy arrange hunting for these little pests. Small graceful and dexterous predators enjoy playing with large and interesting prey, so attractive for its buzz.

And, with no less pleasure, after the games the cats eat their prey. Such a dietary supplement to the usual diet of your pet not only does not harm, but also will benefit, because the fat "dairy" May beetles are really high protein food.
