Occurrence
In Central Europe the species is almost everywhere circulated only locally and rare. It occurs in various habitats in which their food plants grow, such as in oak bush areas, oak forests and hot and sandy heathland.

The nocturnal moths fly mainly from late May to early July, and on warm places in a second generation in August and September. They fly to the artificial light sources. At rest, they hold the wings roof-like. The caterpillar is found from July to September and is when she does not eat, lethargic and sits quietly on the petiole. It pupates in a loose cocoon on the ground. Hibernation takes place in the pupal stage. The pupa overwinters occasionally twice.
