Imago / Adult:

The adult moth (imago) varies between 58mm and 90 mm in wingspan. The ground colour is a gingerish brown. It is a resident species with the males flying wildly during the daytime and the females taking flight by night. It is single brooded with its flight period being between July and August. A localised moth in the Vice-Counties of Cheshire (VC-58) and South Lancashire (VC-59), it tends to be commonest on heaths and moorland.


The larvae vary dramatically in size depending upon both genetic factors and also foodplant nutrition value. They are usually between 65 and 85mm in length, with the female larvae usually being larger than the males. The blackish-brown body is heavily covered with gingerish brown hairs. The head is speckled with grey and brown, whilst the spiracles are distinct and white in colour.


The variety of acceptable foodplants is wide and includes: Heather, bramble, sallow, broom, blackthorn (sloe), hawthorn, ivy and bilberry.


The moth overwinters as a third instar / half-grown larva.
