The dusty (Coniopterygidae) are a family of the reticulated winged (Neuroptera). They occur worldwide with about 300 species, of which in Europe 57 and in Central Europe live again 22 species. The genera can be clearly distinguished on the basis of the different wing veins ; genital examinations are usually necessary to differentiate between species .
features
The clips reach a wing length of 1.8 to 5 millimeters and have, atypical for netwings, wings that are brownish or light-colored with wax dust. This is where the German name comes from. They therefore have a certain resemblance to the plant lice of the Aleyrodidae family , but in contrast to these, their wings are much more steeply attached to the body when they are at rest. In the costal field of the single-colored wings, the animals have no more than two wing veins, which clearly distinguishes them from the other reticulated wings. The forewings also have only a few transverse veins and no wing marks. In some species, such as B. those of the genus Conwentzia the hind wings are reduced, others, like the females of some species of the genus Helicoconis, have no wings at all.
The larvae are about 3.5 millimeters long. Their straight suction tubes are very short and are covered by the upper lip.
Way of life
Most of the crepuscular larvae live on bushes and trees. They predatory feed on aphids , scale insects and mites . The females lay their eggs individually on the bark or on leaves. There are usually two generations per year.
