A very rare, very local and decling species in Belgium. Recent observations only known from a single location in LI and NA.
Hibernates as larva on the food plant. Pupates usually in debris. The adults are easily disturbed by day and later come to light.
The adults fly in one generation a year; from early July towards early September.
The larva lives on Genista and on Cytisus scoparius.
