features

butterfly

With a wingspan of 41 to 54 millimeters, the rolling-wing wooden owl is a medium-sized owl butterfly. The fore wings are narrow and long. Their basic color varies from white-gray to blue-gray to gray-brown. The kidney defects are large and filled with whitish, the ring defects, however, are small. The midfield is mostly darkened. A W mark made up of black arrow spots can be seen near the hem. The hind wings are gray-brown without drawing, somewhat darkened at the edge. The proboscis of the moths is well developed. The antennae of the males are weakly serrated.

Egg, caterpillar and pupa

The spherical egg has a strongly flattened base, is slightly arched inward, clearly ribbed and reddish-gray in color.

Adult caterpillars are brown in color and show broad, yellow longitudinal stripes. They also have yellow dots and a thin, interrupted, yellow-white topline that is bordered by dark brown spots.

The slim doll is equipped with fine thorns on the cremaster .

Geographical distribution and habitat

The distribution of the roller-winged wooden owl extends through almost all of Europe, eastward to the Urals, as well as to Kamchatka and Japan . In the Alps , it rises to around 1500 meters. It is mainly found on boggy terrain, in damp mixed forests as well as in tundra and taiga areas.

Way of life

The moths fly univoltin from August to November. When at rest they roll their wings around their bodies. As a result, they resemble a piece of bark or a broken branch and are thus well protected from predators. They are nocturnal and fly to artificial light sources , also like bait . The caterpillars live from May to July. They feed polyphagous on a variety of plants, of which only a selection is mentioned here:

and other. Pupation takes place in a cave in the earth. The species overwinters in the egg stage.

Danger

The roller-winged wooden owl is widespread in Germany, but seldom in some areas and is classified in category 3 (endangered) on the Red List of Threatened Species , in Baden-Württemberg it appears on the warning list.
