An unmistakable moth with an irregularly scalloped edge to the forewing. At rest the wings are folded like a tent over the body resembling a dried leaf. There are two dark parallel cross-lines and a small dark dot between them. The females are more yellow-orange in colour whereas the males are more grey-brown.
The adults fly at night and are attracted to light. The larvae can be seen from June to July and August to September before overwintering as pupae in a folded leaf from the foodplant, dropping to the ground with the leaves as they are shed before winter.
