A very rare and local species in Belgium.
The adults fly in May and June. They are active in the evening and later come to light.
The larva feeds in a spun leaf on a terminal shoot of Populus tremula, preferably a young tree. Pupation in a turned-down edge of a leaf which falls to the ground where the pupa hibernates.
