The larva lives on the underside of the leaves of the host plant. It consumes the leaves and thus creates round holes in the leaves in between the veins. The caterpillar is full-grown at the end of August or beginning of September. Pupation takes place in a soft spinning in the ground. The species hibernates in the pupal stage. The adults come to light.
