Small Emperor Moth

The male has a wingspan of about 60 mm (2.4 in) with brown and white forewings marked with red and orange fascia and a bold black and orange eyespot. The hindwings are orange with a similar eyespot. The female is larger with a wingspan of about 80 mm (3.1 in), but less brightly coloured than the male, being generally grey and white but has all wings marked with eyespots similar to the male. The male flies rapidly during the day from mid-April to late June looking for the rather sluggish females, which usually only fly at night. The species inhabits a range of habitats but is most often associated with heathland and moorland. The caterpillar is black and orange at first, later becoming green with black rings and yellow and red spots. The commonest food plant is heather but the species has also been recorded feeding on a huge range of other plants (see list below). The species overwinters as a pupa within a fibrous cocoon.
