Used to be a fairly common species in the south of Belgium, but has become very rare now.
Native
Hibernates as a pupa, in a tough cocoon of silk and chewed bark on a twig on the food plant. The adults are active from dusk onwards and later come to light.
The adults fly in one generation a year; from mid May till late July.
The larva lives on young shoots and leaves of Populus tremulifolia and Salix.
