Locally fairly common in some forests in central and southern Belgium, elsewhere rare.
Hibernates as a pupa in a though cocoon among plant debris. The adults are active during the day and later come to light.
Depending on weather conditions, the adults can be seen from the last decade of March till the beginning of June in one generation a year.
The larva lives on several tree species with a preference for Fagaceae, like Fagus, Betula, Alnus glutinosa, Alnus incana, Salix caprea, Sorbus aucuparia, Tilia cordata, Quercus and Corylus avellana.
