A very rare species with only records before 1980 in the southern part of Belgium. Very likely extinct.
The moths are active from dusk onwards and later come to light.
The adults fly in two generations a year from April till July and again from August till September.
The larva lives on Quercus.
It occurs almost everywhere in oak forests with coppices, but localized in the warmest places.
