A very common species throughout Belgium, sometimes very abundant.
The adults fly from mid May till the end of August. They are easily disturbed by day and come readily to light.
The larva feeds on various grass species. It lives at the stem-bases of grasses, without making a silken gallery. Pupation in a cocoon on or under the surface of the ground, in which the larva has overwintered.
