A rare species in Belgium, most observations from the Kempen area and the southern part of the country.
The larva lives in a tubular, frass-covered web on the food plant. Pupation takes place in a thick white cocoon in the earth or at the base of the food plant.
The adults are active at dusk and later come to light.
The adults fly from mid June till late September.
