A not so common species throughout Belgium. In the male, the upperside hindwing has a doubly-folded lobe along the dorsum towards the base. This character is shared with Pterapherapteryx sexalata.

The larva lives on several species of Populus, but especially on Populus tremula. Hibernates as pupa in a cocoon underground.

The adults fly from mid April till early July. They are active from dusk onwards and later come to light.
