Occurrence
The animals are common and most often in Europe and eastwards through to East Asia before, also in Morocco and Iran. In the Alps, they are still to be found at altitudes of over 2,000 meters. One finds the way in dry and in moist habitats, such as in bogs, streams and rivers, but also in nations, and as a successful synanthropic in parks and gardens.
Way of life
The butterfly sit during the day in rest position with closely over the abdomen folded wings. The front legs are pre-stretched and stretched through the abdomen tip with the after Busch up between the wings. They are nocturnal and be attracted by artificial light sources. The females lay eggs on the food plant. The caterpillars hide during the day between each other spun leaves, pupate there in a white-gray cocoon and hibernate. The caterpillars feed on the leaves of various species of poplar (Populus ), such as aspen (Populus tremula ) and willow ( Salix). The moths fly in two generations per year, from early April to mid-June and from late July to late August.
Endangering
The species is not endangered.
