A not so common and local species in Belgium, though widespread.
The adults fly in two generations a year; from mid May till late September. They come to light.
The larva lives mainly on Quercus, but also on Fagus and Castanea sativa, even on the fallen leaves. Hibernates as a pupa in a cocoon among plant debris.
