The Eastern owlfly ( Libelloides macaronius ) is a lacewings from the family of owlfly (Ascalaphidae).
description
The species reaches a wingspan of 38 to 55 millimeters. It looks very similar to the long-nosed butterfly ( Libelloides longicornis ). It also has lemon-yellow wing veins, albeit with a yellow spot on the forewing base, which runs along the vein near the edge of the wing, and another two black spots to the left and right of the middle of the wing. The hind wings are opaque lemon yellow, on the wing base and around the wing tip are large black spots. The spot on the wing tip again has a slightly transparent yellow spot in its center. The body, like the long antennae , which are thickened at the ends, is colored black.
The compound eyes of the superposition type are fully UV-sensitive and each divided into two parts. Each superposition eye contains about 300 ommatidia . The UV sensitivity supports the hunting of flying insects even at great heights, since even a small object appears as a high-contrast black spot against the cloudy and cloudy sky.
The larvae look like those of the ant maids ( ant lions ), but are flatter and wider. They also have wart-like extensions on the sides of the abdominal rings. They hunt for insects on the ground and do not build funnels.
Occurrence
Eastern butterflies live near scree fields, but also in bushy terrain. They come in places in eastern Central Europe , such as B. in Austria , but especially on the Balkan Peninsula . In Germany they are not native.
