features

butterfly

The wingspan of the moth is 36 to 46 millimeters. The color of the upper side of the forewing varies from slate gray to dark blue-gray. Sometimes it is slightly silky scales. A narrow white-yellow lightening can often be seen at the wing root. Ring and kidney defects stand out only indistinctly. The same applies to the transverse lines. Noticeable are a black root welt, which is bent into an L-shape, as well as a black longitudinal line that replaces the cone blemishes . The upper side of the hind wing is unmarked gray-brown. The proboscis is well developed. There are no back hairs on the abdomen.

Egg, caterpillar and pupa

The hemispherical egg is covered with distinct ribs and initially has a yellow color, which later changes to rust-brown. The caterpillars are grass green to bluish green in color and show whitish back and side back lines. A pattern made up of many very small white dots and spots extends over the entire surface of the body. The head capsule is also provided with white spots. The doll shows a two-pointed cremaster on which there are some bristles. In a cocoon laid out on the ground and spun with leaves and moss , the caterpillar only turns into a pupa after several weeks of rest.

Way of life

The moths fly in one generation from the end of September. They overwinter and live until the beginning of June of the following year. They are nocturnal and fly to artificial light sources as well as bait . The caterpillars live mostly from May to July. They prefer to feed on the leaves of the Gagelstrauch ( Myrica gale ). Bogberry ( Vaccinium uliginosum ), birch ( Betula ), alder ( Alnus ), willow ( Salix ) and poplar ( Populus ) are also named as other food plants .
