A not so common species in Belgium, mainly distributed in the northern part.
The larva lives in a leaf of the food plant spun together into a pod. When full-fed, it makes a cocoon in that larval habitation in which it hibernates. It pupates in the spring.
The adults are active at dusk and later come to light.
The adults have been observed from late April till well in June.
The larva lives in a leaf of Rhamnus or Frangula1
