A fairly common species throughout Belgium, more observed in the north of the country.
The larva feeds in a silken gallery on the surface of the soil. Pupation takes place in a long, narrow, silken sand-covered cocoon. The adults are active at night and come to light.
The adults fly from July till mid-September.
The larva feeds on Bromus or other grasses.
