A rare species in many parts in Belgium.
The larva lives in a silken tube in the roots of the food plant where it hibernates.
The males fly around the food plants in early evening, when the females may be found resting on the leaves. They come to light.
The adults fly from early June till towards early September.
It inhabits damp places, fens, grasslands and woodland edges.
