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