Top 20 Most Common Insects in Volsk

Issoria lathonia is a medium-sized butterfly with a wingspan of 4 - 4.5 cm. The wings show a deep orange-violet background, with rounded black spots arranged in regular rows and suffused with greenish gray in the females. The underside of the hindwings is decorated with large pearly nacreous spots and it is crossed by a postdiscal row of black eyespots with pearly pupils. Some pearly spots also appear at the apex of the forewings. The caterpillar can reach a length of 3.5 cm. It is grayish brown, with black spots, and relatively short brown spines with white tip, and a double row of dorsal white streaks. The suspended chrysalis is dark brown, with a large white saddle-shaped stain and some smaller ones of the same color, resembling a bird's dropping. The imago is rather similar to Argynnis aglaja, Argynnis adippe and Brenthis daphne, which have the same orange color on the upperside of the wings, but show different markings and spots. Moreover, the underside of the hindwings does not have the large pearly spots characteristic of the queen of spain fritillary.

Melanargia galathea has a wingspan of 1.8–2.2 in. In these medium-sized butterflies the upper side of the wings is decorated with white and gray-black or dark brown markings, but it is always gray-black or dark brown checkered in the basal and distal areas. The underside is similar to the upper side but the drawings is light gray or light brown. On the underside of the hindwings is present a row of gray eye spots. The males and the females are quite similar, except that some females may have a yellowish nuance on the underside of the wings. The larvae are a lime-green colour, with a dark green line running down the middle of their back. The caterpillars are about 3 cm long. They are green or yellow with some lighter and darker narrow longitudinal lines. The head is always light brown.

A popular pollinating species in European greenhouses, buff-tailed bumble bee (Bombus terrestris) is one of the more common species of bumblebee worldwide. This species displays comparatively high levels of intelligence, recognizing flowers by color and navigating several miles (if necessary) to return to the hive. Unlike many other bee species, the queen of a buff-tailed bumble bee hive will only mate with one male.

The old World swallowtail (Papilio machaon) is commonly just called the "swallowtail," giving it the added title of "old world" to distinguish it and remind us that it comes from the "old world" (Asia, Africa, Europe). The upper side of them is a beautiful combination of pure white with black striping, the underside being a brownish version of the same thing. There is blue and two red dots on its back side.

Stenurella bifasciata can reach a length of 6–10 millimetres (0.24–0.39 in). Head, antennae, pronotum and legs are black. Pronotum is slightly punctured. Elytra are yellow brown in the males, while in the females they are red, with a widely darkened elytron's suture, black apices and a black heart-shaped or rhomboid marking, sometimes missing in the males. The last three abdominal segments are usually red. The eleventh (last) antennal segment is longer than the tenth.

Given its name, it's no surprise that forest bug lives in woodlands, forests, and gardens. Its sharp mandibles are adapted to gain access to the sap on which it feeds, although it is also known to predate on other insects. It prefers oak trees but also feeds on fruit trees, making it an occasional agricultural pest.

The four-spot (Libellula quadrimaculata) is one of the large dragonflies and reaches a body length of 4 to 4.5 centimeters with wingspan between 7 and 8.5 centimeters. Each of the four wings has a striking dark spot in the area of the distinctive transverse vein (nodus), after which the species received both its scientific and its trivial name. This dragonfly is also known for its mass migrations in swarms of impressive dimensions. The entire stock is not considered to be threatened.

The body length is about 50 millimetres in males and 70 millimetres in females. The cricket is dark brown with a silky shimmer and yellowish underside and is covered with fine velvety hairs. The forelegs are powerful and modified for digging. The elytra are half the length of the abdomen and the wings are transparent and netted with veins. They are folded into pleats and seldom used as the cricket normally remains below the ground. The males can be distinguished from the females by the open vein area in the forewing known as the 'harp' while the females lack the external ovipositor that is possessed by other crickets.

It is a fairly large dragonfly (the length of 4.5 - 5 cm, 3 - 3.5 cm abdomen, rear wing 3.5 - 4 cm.) with relatively broad, flattened abdomen, but not as broad as to chaser species. With age, adult males develop extensive blue pruinescence on their abdomen, offset by yellow lateral patches. The middle lobe of the pronotum is large and notched in the middle. The chest is yellow or yellowish-brown. The base of the hind wings do not show a dark opaque spots. The pterostigma is dark brown or black. On the front wings pterostigma 2 - 3 mm long. Anal appendages are black. The females and immature males are a deep yellow color, with wavy black lines dorsally on their abdomen. Males and females have the costal vein (the leading edge of the wing) yellow or black.

The birch shieldbug (Elasmostethus interstinctus) is like other stink bugs in the fact that they produce a foul-smelling odor when threatened. When they aren't being stinky, you can take a moment to appreciate their x-shaped red markings. Their eggs are laid on the upper side of birch leaves, where their nymphs are able to feed.
