A very rare and very local species in Belgium. Most observations are in the southern part of Belgium. A very tiny population occurs at the coast in Ostend (WV).
In some southern locations the species is not rare, especially in calcareous area's.
Hibernates as a pupa in a cocoon among plant debris. Adults can be seen during the day, but are most active from dusk onwards and later come to light.
The adults fly from May till mid July, in most years a partial second generation occurs from August till late September.
The larva lives on Galium.
