features

butterfly

The wingspan of the moth is 26 to 32 millimeters. The basic color of the upper side of the forewings varies from gray-brown to mouse gray to bluish gray. The outer edge is strongly convex. Three straight, brown, yellow transverse lines stand out clearly, the inner one bends towards the front edge and the outer one opens into the wing tip. A row of small black-brown points runs in front of the hem. The upper side of the hind wings is light gray-brown with little drawing and sometimes shows a short, dark transverse line that begins at the anal angle . In the resting position with the wings folded like a roof, the palpi are pointed forward.

Caterpillar

The caterpillars are 14-footed, light green in color and have a dark green back line. The segment incisions are yellowish.

distribution and habitat

The distribution area of ​​the willow spider owl extends from northern Spain and southern Italy further east to the Urals . The species is also found in eastern China as well as in Japan and Korea . The main habitat are swamp and swamp forests, riparian areas and humid meadow valleys.

Way of life

The moths are diurnal and nocturnal and fly in one generation from the beginning of May to the beginning of August in the predominant occurrence areas. In some southern regions, a second generation appears in August and September. During the day they sometimes fly in the sunshine. At night they appear on artificial light sources , rarely on baits . The caterpillars feed on the leaves of willow ( Salix ) or poplar species ( Populus ). The young caterpillar prefers to eat on the underside of young leaves. The pupation takes place in a well-camouflaged cocoon of Borken- and web parts to a branch of the food crop. The species overwinters in the pupal stage.
