Distribution and habitat
The Schwarzgefleckte Raufußspinner is widely used in Europe and is heading east through northern Asia to China, Japan and Korea before. He can still be found at altitudes up to 1600 meters. The species prefers inhabited stream and river valleys and floodplains and swamp forests.
Way of life
The moths form two generations per year, which are found in the months of April and May and June to August. Whether later in the year belong to specimens found further generations, needs clarification. In Northern Europe they are univoltine and fly in June and July. The butterfly sit during the day in rest position with a roof shape over the abdomen folded wings on the trunks and branches and stretch the abdomen tip with the after Busch up between the wings through. At night they visit artificial light sources. The caterpillars feed on the leaves of various poplar (Populus ) and willow species ( Salix). They like to hide in rolled and spun leaves. Pupation takes place in a white-gray cocoon. The doll of the last generation winter.
