A fairly common species in the Kempen, elsewhere in Belgium rare and very rare in the southern part of the country.
Native
In the early stage, the larva lives on the buds and later on the leaves of its host plant.
Hibernates as an egg, laid in small batches on twigs of the food plant. Pupates underground in a cocoon.
The adults come to light and sugar.
The adults fly in one generation a year, from late August till the end of October.
The larva lives on Quercus, sometimes also on Corylus and Crataegus.
