Flight periods

The adults have been observed from late May till the end of July, and a partial generation occurs in August. The moths are active in the evening and later come to light.

Observed on

Host plant (genera):

The larva feeds in the berries of Frangula alnus, spinning two or three together. It sometimes occurs also on Hedera, Lonicera or Swida. When full-fed it constructs a leaf-case amongst detritus on the ground or attached to a stem, overwintering therein. Pupation in that leaf-case. A few larvae pupate already in summer or early autumn, producing a second, partial generation.
