A fairly common species throughout Belgium.
The adults fly from late April till the end of June. They are active in early evening and later come to light.
The larva lives in a leaf of Quercus or Fagus spun into a pod. It hibernates full-fed in the larval feeding place. Pupation in the pod where the larva overwintered or in leaf-litter.
