A rather rare species throughout Belgium, mainly observed in the Kempen.
Hibernates as a larva and pupates in a cocoon among plant debris or near the base on the food plants.
The adults fly usually in one generation a year; from mid June till end of August. Very rarely, a partial second generation occurs from September till well into October. They come to light.
