A rare and local species in Belgium, mainly observed along the coast and along the river Schelde in AN.
The larva is active at night and hides into the sand during the day. Hibernates as a full-grown larva in a cocoon deep in the sand, where pupation takes place in spring. The adults are active from dusk onwards and later come to light and sugar.
The adults fly from mid May till August.
