A not so common but widespread species in Belgium.

The larva lives mainly on Quercus , but it's also noticed on Fagus and Betula. Hibernates as a pupa usually in bark crevices or among plant debris.

The adults fly in one generation a year; from mid April till June, with a peak during May. It's possible to see a small number of specimens during August, and it is not certain yet whether these individuals are part of a partial second generation or belong to a delayed  first generation. They come to light.
