A very common species throughout Belgium, sometimes very abundant.
Native
The larva 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.
The adults are easily disturbed by day and come readily to light.
The adults fly from mid-May till the end of August, occasionally later.
