A not so common species throughout Belgium, more observations in the Kempen and southern part of the country.
The adults fly from early April till the end of May. They come to light and infrequently on sugar.
The larva lives on Quercus and feeds at night and rest by day on the underside of a leaf. Hibernates as a pupa, in a compact cocoon formed underneath moss at the base of a tree, in leaf litter or in soil.
