The dark-winged filly is an incredibly slender and very agile pest. It lives in most areas of the forest-steppe and steppe zones of the south, as well as in the middle zone of the European part of Russia. In addition, this scoundrel can be encountered in Kazakhstan (including in its mountainous regions), in the mountains of Central Asia, throughout Siberia and the Caucasus. Dark-winged filly are especially fond of the areas rich in vegetation, where grasses predominate. And they harm mainly eggplants, peppers and grain crops
Meet the pest
Females of the dark-winged filly grow in length from 21.8 to 27.2 mm, and males from 17.8 to 20.3 mm. As for the size of the elytra, in females they usually range from 17.8 to 20.3 mm, and in males - from 17.7 to 19.2 mm. Filiform thin antennae of voracious parasites extend beyond the posterior margins of the pronotum and lack thickenings in the apical parts. And if you look at the dark-winged filly in profile, you will notice that their foreheads are rather strongly inclined.
All dark-winged filly are characterized by a dark green or brownish color. Sometimes on their pronotum one can notice a couple of black velvety stripes. As a rule, concave and slightly arcuate lateral carinae of a whitish color are clearly distinguished on them.
Both the wings and the elytra of the pests are equally well developed. Near the bases of the elytra, the precostal area is slightly widened, and slightly at a distance it sharply narrows, without going too far beyond the middle. And the transverse stripes on the bodies of the pests are noticeably thickened and have the correct shape.
The wings of dark-winged filly are colored in dark brown, almost black tones, and their main longitudinal veins are noticeably thickened. In the apical parts of the wings, distinctly curved subcostal and costal veins can be seen, and the margins of the anterior parts of the wings are slightly widened. The hind femora of harmful parasites are colored dirty brown, and their red hind tibia are equipped on the inner sides with tiny lower spurs, which are slightly larger in comparison with the upper spurs located in the same place.
The hatching of voracious larvae begins approximately in mid-May (as a rule, it first occurs in the mountainous regions of Kazakhstan). Each individual goes through four ages and completes its development in about thirty to thirty-five days. And a week and a half after fledging, the harmful parasites mate. Pest egg capsules are usually deposited on areas with not particularly dense vegetation cover and relatively light soils. And then the females gradually migrate to densely vegetated areas, located mainly on their outskirts. The egg-pods laid by females are rather short, have an oval shape and are strongly narrowed on both sides. In length, they usually reach about 7-10, 5 mm, and their diameter can vary from 3 to 5 mm.
Each pod contains from one to ten eggs, and a little less often eleven eggs can be found in them. The eggs occupy almost the entire area of the egg-pods - they are arranged there in three vertical rows. At the same time, the outer rows contain three eggs, and the central rows contain four.
The shiny smooth eggs of dark-winged filly are yellow and have a slightly curved cylindrical shape. At the lower poles, they are slightly drawn out, and at the upper ones, they are widely rounded. In diameter, eggs reach the order of 1, 3 - 1, 5 mm, and in length - from 4 to 5, 6 mm. And around the eggs, and between them, you can see a frothy translucent and fine-celled mass, painted in reddish-yellow tones. Exactly the same mass forms the thin walls of the egg capsules.
How to fight
The vegetation attacked by dark-winged filly begins to be sprayed with "Karbofos" or "Aktellik". Such preparations as "Iskra" or "Fas" are also excellent for this purpose.

Dark Seed Nutcracker Is The Enemy Of Vegetables
The dark sowing nutcracker is a polyphagous pest that lives almost everywhere. Most often, it is found in the northern forest-steppe and in the mountainous part (mainly in the western regions). The larvae of these parasites cause serious damage to all kinds of vegetables, root crops, as well as corn. To one degree or another, almost all agricultural plants can suffer from its harmful activity

Dark aquilegia (Latin Aquilegia atrata) - one of the most unusual species belonging to the genus Aquilegia of the Buttercup family. In nature, this representative lives on the rocks and calcareous areas of the Alps - the highest and longest mountain range located in Europe.
