A not so common and local species in Belgium. Formerly known only from the southern part, but since 1980 spread over almost the whole country together with its foodplant which is planted in gardens.
The adults fly in two generations a year: in May and June and again in August. They are active from dusk onwards and later come to light.
The larva lives on Berberis vulgaris, but also on cultivated plants. Hibernates as pupa in a loose cocoon, often among plant debris but usually deeper under the ground.
