features
butterfly
The wingspan of the moth is 28 to 38 millimeters. Their basic color ranges from yellowish to gray-brown to red-brown. They point to the front wings a darkened midfield, which will be narrowed and the center to the front edge bordered by dark transverse lines. The hind wings shimmer in the color of the forewings and sometimes show an indistinct transverse line. The antennae of the males are double-combed, those of the females are slightly sawtooth.
egg
The egg is yellowish with red spots or solid dark red. It has an oval shape and is covered with a very fine network.
Caterpillar
The caterpillars are reddish brown or purple-gray in color, have yellowish mottling and double, wavy, brown side lines. A flat transverse hump can be seen on the ninth segment.
Doll
The red-brown pupa is straight and elongated. There are three very small bristles on the wide cremaster .
Similar species
There is a certain similarity to the brown coniferous forest spanner ( Pungeleria capreolaria ), which, however, shows a clear dividing line in the tip of the forewing and a black discal spot.
Geographical distribution and occurrence
The powder chuck is common in Europe and Asia and is also found in North America. In the Alps it rises up to 2000 meters. The species is found in mixed deciduous forests, shrubbery and woody blueberry areas.
Way of life
The moths fly in a first generation from late March to late June and a smaller second generation from early July to late August. They can be attracted by artificial light at night . The caterpillars feed on the leaves of various hardwood species, including: hazel ( Corylus avellana ), common bird cherry ( Prunus padus ), mountain ash ( Sorbus aucuparia ) and willow - ( Salix ), alder - ( Alnus ), birch - ( Betula ) and Oak species ( Quercus ), also bilberry ( Vaccinium myrtillus ). The pupae overwinter.
Danger
The powder tensioner is listed on the Red List of Endangered Species as not endangered.
