The Emperor Moth is a moth of the family Saturniidae. It occurs throughout Europe and is the only member of its family found in the British Isles.

The male has a wingspan of about 60 mm with brown and white forewings marked with red and orange fascia and a bold black and orange eye-spot. The hindwings are orange with a similar eye-spot. The female is larger (wingspan about 80 mm) but less brightly coloured than the male, being generally grey and white but has all wings marked with eye-spots similar to the male.

The male flies rapidly during the day in April and May, 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 larva 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 blackthorn, bramble, hawthorn, meadowsweet and sallow. The species overwinters as a pupa within a fibrous cocoon.
