Caterpillar
The caterpillar has two colour forms: a greenish one and a dark grey-brown one. The white sideline is characteristic because it continues till the head. Between all segments a rather narrow greenish-yellow transverse band (not in the dark form). Head capsule green to dark green, black in the dark form.
Bionomics
The species hibernates in the pupal stage. The dark brown, sometimes black pupa is constructed underground.
The adults are active during the day but also come to light. Their flight starts in the morning and the moths are still active in the late sunset hours.
Flight periods
The adults fly in two generations a year, difficult to separate from late April till well in October.
