A very rare and local species in Belgium, largely limited to the southern provinces with a stronghold in the Calestienne area where the species is not so rare.
Hibernates as pupa.
The moths come readily to light.
They fly in two generations a year and have been observed from mid April till September, the second generation often less abundant.
The larva is monophagous and can be found on Quercus.
