A fairly common and widespread species in Belgium.
Hibernates as a pupa usually in bark crevices or among plant debris. The adults come to light.
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 July and August, and it is not certain yet whether these individuals are part of a partial second generation or belong to a delayed first generation.
The larva lives mainly on Quercus, but it's also noticed on Fagus and Betula.
