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