A rather common species throughout Belgium.

The larva lives in a folded leaf on the food plant. It pupates in a flimsy cocoon amongst detritus on the ground and hibernates as a pupa.
The adults use to rest on trunks during the day and later come to light.
The adults have been observed from mid-April to late July.
The larva lives on Betula or Alnus.
