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.
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 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... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Small Emperor Moth is recorded against all the insects logged in Birmingham (10 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
