In the area of the probe tip are two white rings. The forewings are white and heavily speckled with dark gray scales. By Kostal fold passes near the wing base, a broad blackish line which is interrupted in the middle and distal to yellowish white spots. There is an indistinct blackish spot, which almost reached the line of blackish costal fold at the base of the wing inner edge. In the middle of the forewing is blackish line which is interrupted in the middle by a yellowish white spot. A broad, yellowish white line extends from the wing base to 2 /5 of the forewing. In Tornus ( internal angles ) are yellowish white spots. In the apical region, three yellowish white lines are on the costal vein, two yellowish white lines range from Saumfeld to the inner angle. The fringe scales are mixed gray and white on the wing tip. The hind wings are shiny gray and brighter towards the wing base.

Biology
The oligophagen caterpillars live on different pasture plants such as the white poplar (Populus alba), aspen (Populus tremula ), White Willow (Salix alba) and goat willow (Salix caprea ). They develop from April to June ( according to other sources from May to June ) in the female catkins of willows and poplars, where the first crawler stages nate in flowers and seeds. Later stages live in silken cocoons between the seeds. Sometimes the caterpillars bore into the buds also based in these caves and they completely. The partially ejected faeces is visible in the form of a small pile will in the center of the bud. The last stages of caterpillars also eat between young leaves. The full-grown caterpillar leaves her cocoon to pupate in cracks of the bark of their host plant. The very slim brown dolls are in a tapered felt-like cocoon, which is covered with lichens parts. The time of flight of butterflies stretches from June to August, after another source from the second half of June to early September. The moths often run around on tree trunks and are attracted by artificial light sources.
