A very rare and local species in Belgium. First observation in WV on 31 August 2006. Nowadays mainly confined close to the French border in West-Vlaanderen.
The adults fly in one generation a year; as early as May till October, but usually seen during August and September. They are active from dusk onwards and later come to light.
