A very rare and local species in Belgium, only known from a few locations in the southern part of the country.
Hibernates as a full-grown larva in a cocoon. They are easily disturbed by day. They are attracted to light.
The adults fly in one generation a year: from end of April till end of July. When conditiones are favourable, a partial second generation occurs from August till mid September, sometimes as late as mid October.
The larva lives on various species of Galium.
