This very rare and local species has not seen in the southern part of Belgium for quite some time.
Egg laying on the underside of the leaf. The noctural larva lives freely on the leafs of the food plant and can be found at night on the basal leaves during August. The pupa hibernate once. Pupation occurs in the immediate vicinity of the food plant in a fairly solid cocoon on the surface of the earth.
Adults rest hidden during the day, usually close to the ground under leaves and later come to light.
The adults are on the wing from May towards July.
It inhabits xerotherme places were the food plant is abundant.
