A fairly common species throughout Belgium in suitable habitats, with most observations in the Kempen.
The caterpillar mainly forages at night and rest during the day on the host plant. Hibernates as a larva or as a puppa in a tough cocoon on or underground. The adults are active during sunny days and later come to light.
The adults fly in two, sometimes three, hard to define generations a year from mid April towards October.
