Mating of Asian leaf beetles Chrysochares asiatica (Pallas, 1771). The leaf beetle is found in the south of Russia, the Caucasus, and Central Asia. Prefers meadows. It is very rare everywhere.The picture was taken in the Astrakhan region.Author: VO
Ktyr (Asilidae). About 5000 species of the family inhabit steppes and deserts. The saliva of ktyri contains a strong poison, from which insects die instantly. For a human, a sting is as painful as a bee sting. Ktyr larvae are predators. In the soil, they chase the larvae of other insects. Larvae can withstand prolonged starvation.The picture was taken in the Astrakhan region.Author: VO
Redneck beetle (Anisoplia segetum), a beetle in the Laminidae family. Body length is 8-12 mm, color is greenish-black, elytra are reddish-yellow, in the female-with a black spot near the scutellum; the underparts, head and pronotum are covered with thick hairs. A pest.The picture was taken in the Astrakhan region.Author: VO
Speckled filly (Heteracris adspersa). Causes damage to various cultivated and wild plants. It is common in the lower Volga region. Eggs are laid in the soil. Laying a portion of eggs, fill them with foamy secretions of the adnexal glands. This mass, with soil particles stuck to it, hardens and forms a pod.The picture was taken in the Astrakhan region.Author: VO

Jaundice (Colias sp.). Size (40-50 mm) Butterflies of the first generation fly from mid-May to mid-June, the second generation-from mid-July to mid-October. The last generation is very numerous in some years. It lives more often on plains; it is common in clover and alfalfa fields, as the caterpillars feed on legumes.The picture was taken in the Astrakhan region.Author: VO
The lumpy wasp (Cerceris) captures small goldenrods, weevils, and leaf beetles, paralyzing them. These wasps often live in large colonies. The entire surface in such places is covered with craters of discarded earth, and the soil at a shallow depth, like a sponge, is pitted with wasp burrows.The picture was taken in the Astrakhan regionAuthor: VO
Scoliopterix libatrix (Linnaeus, 1758) is a medium - sized moth. Butterflies and caterpillars are active at dusk and at night, hiding in secluded places during the day. Caterpillars feed on leaves and stems, and are carriers of agricultural crops. Pupation occurs mainly in the soil, and in summer generations-on the surface of the soil or on plants in a spider cocoon.The picture was taken in the ...

Sirphida (Spherophoria scripta). Like most cerfids, it mimics the color of hymenoptera. This similarity serves as a means of protection for flies. They are active on sunny days on flowering plants. They are common in the lower Volga region. The picture was taken in the Astrakhan regionAuthor: VO
Catocala neonympha. The butterfly's distribution area is in the south of Russia, Kazakhstan, Turkey, Iran, and Afghanistan. The species is sedentary, producing one generation per year. It flies from July to October. It is found in groves, trees and shrubs near water bodies, and in gardens. The eggs overwinter.The picture was taken in the Astrakhan region.Author: VO
"But it has SUCH a healthy proboscis-2 mm! Lice don't have that kind of thing."Of course-the elephant is also not some kind of mouse. But still the proboscis is long: is this enough for the squad?
Byavaet, but rarely (just like me on this Forum )Bryan's recent "Social insects" for 120 rubles. snapped up.To be honest, "second-hand books" have almost died out, the merchants broke such a percentage for the sale that it is simply unprofitable for people to hand over books there. It is more realistic to find something interesting on book street ruins with junk and books (in fact, in Soviet ...
After Yulia clarified the biotope in which the butterfly was photographed, we can definitely say that it is petrovitana.Proposed new signature:St. Petersburg velvetLasiommata petrovitana (Fabricius, 1787)The butterfly got its name because in the vicinity of St. Petersburg - its typical location.It flies in May and June. The caterpillars feed on cereals (Poa sp., Calamagrostis epigeios, Festuca ...

I think these are mosquitoes from the family Trichoceridae, or winter mosquitoes. They are quite common for such temperatures, and constantly form swarms.Did they? But they didn't really turn out to be "winter": they didn't live to see the real winter, and I read that they can fly right over the snow (at slightly negative temperatures). Or are they just short-lived?
So, this species is not such an obligate phytophage? I didn't say that. Sometimes they still end up on the ground, but not far from the pines.You won't be able to scan it (mounted, mustache and legs spread out - it will break), but it's better to send it for detection.This post was edited by Helene - 01.11.2005 12: 07
I looked at the map. As for the main part of the range, it is certainly questionable. But there is also an incompleteness. In particular, the Caucasus region is not fully taken - there is a window on the right "tip" of the Black Sea coast (and then, across the isthmus, it continues). However, my friends in these places, and I myself in the vicinity of them caught the Caucasian subspecies in large ...
To clarify the ranges of Athamanthia and Neolycaena species in the Northern Tien Shan, we need data on these genera (or data on the material) from the Kyrgyz Ridge, Kutmen ridges, Zailiysky Alatau, Kungei Ala-Too, Terskey Ala-Too, as well as from the Chui and Issyk-Kul basins.

We need to find the source of the infection.Now should be the moment of truth. Drosophila in nature disappeared completely. If the fly agaric is still crawling, it means that something is in the house.
The wing is covered with tiny (approximately 20µm) scales. Bright color and shine are provided not by pigments, but by the interference of light on the scales (as in an oil film on a water surface). Light microscope, 860x
This is a late-stage larva of Drosophila melanogaster. You can clearly see the almost formed intestines and tracheae running along the entire body.
Larvae of Drosophila melanogaster of the fifteenth stage of development. The muscle phenotype is clearly visible due to the GFP marker.
The Spanish Peacock's Eye butterfly (Graellsia isabellae) lives in Spain and the French Alps. This rare and protected species is famous for the bright color of the wings — it seems that someone's eyes are looking at the observer. In case of danger, the butterfly opens its wings sharply, and this pattern scares off the predator. The black "pupil" of the eye reaches 5 mm in diameter.
Decorated bedbug (E. ornata) Agricultural pest. It is widespread in the steppe and forest-steppe zone. It feeds mainly on cruciferous plants. Adult bedbugs spend the winter gathering in groups under various plant remains, often in leaf litter under the cover of woody plants. In the spring, after a period of intensive feeding, the beetles mate and the females start laying eggs. Postembryonic ...
Plavunets (Rhantus suturellus). In the Volga Delta, after the spring flood, a lot of small reservoirs remain, some of which dry up by the end of summer, and the swimmers willingly settle them. It is a predator that hunts other invertebrate inhabitants of the reservoir, they are mainly insects, mainly mosquito larvae, including malarial ones. Plavunets is a great flyer. After the reservoir dries ...
The hanging willow or babbler (family Syrphidae; Helophilus pendula = Tubifera pendula) is a common inhabitant of meadows. It feeds on the nectar of flowers. Size 10-15 mm. Larvae develop in water. It is easy to distinguish from other babblers by the vertical yellow stripe on the head.Author: VO
The family of Babblers is Syrphidae. An adult fly with a brownish breast and a yellow-black spotted belly is very similar to a bee. Noteworthy is the larva of the beekeeper, which is called "rat". The body of the larva is barrel-shaped, indistinctly segmented. The last three segments of the abdomen form a characteristic "tail" - a breathing tube. These segments are thin, and each subsequent one ...
