Emperor
Saturnia pavonia

Saturnia pavonia, the small emperor moth, is a moth of the family Saturniidae. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Sometimes, the incorrect genus name Pavonia is still used for this species. This moth occurs throughout the Palearctic region and is the only member of its family to be found in the British Isles, where it is usually called simply the emperor moth. Source
