A rather common species in Belgium, especially in the northern part.
Hibernates as young larva and pupates in a loose cocoon between leaves of the food plant.
In favourable years a small partial second generation occurs during September. They come to light, especially the males.
The adults fly in one generation a year: from late May till early July.
The larva lives on Quercus.
