A very rare and local species in Belgium, known mainly from the southern part of the country.
Hibernates as a small larva near the base of the food plant. Pupates on the ground amongst plant debris or in earth.
The adults are active from dusk onwards and later attracted to light.
The adults fly in one generation a year: usually from mid July till early September, but sometimes even to early October. Biggest numbers during August.
