A very rare and widespread species throughout Belgium.
The adults fly from mid June till mid August. They are active in sunshine and sometimes come to light.
The larva lives in the berries of Crataegus. Two or three berries are spun together and the larva hibernates from October in this cocoon. Pupation in a cocoon under loose bark, in rotten wood, or amongst leaf litter.
