A very rare and local species in Belgium, mainly observed in the south of the country.
It hibernates as young larva and pupates in a cocoon attached on a twig of the food plant. The adults come to light and sugar.
The adults fly from mid June till early August.
The larva lives mainly on Quercus, rarely on other trees like: Fagus sylvatica, Tilia and Prunus domestica.
