A rather common species throughout Belgium.
The adults fly from mid May till July. When conditions are favourable, a partial second generation occurs from August till mid October.They become active from dusk onwards and later come to light and sugar.
The larva lives on withered leaves of Fagus, Quercus and Rubus. Hibernates as a fully grown larva and feeds until October, when it forms a slight cocoon among plant debris, in which it pupates in the spring.
