A very local and rare species in Belgium. Most observations in the Kempen area.
The larva lives in a slight web on the top shoots, preferring the flowers of the food plant. Pupation in an earthen cocoon, rarely in the feeding place. The adults fly in sunny afternoons and later they come to light.
They have been observed from September and after hibernation again till late May.
