Scientific name: Hesperia comma
Easily distinguished from other skippers by the numerous silvery spots on the underside of the hindwings.
A small butterfly with a low darting flight, restricted to chalk downland in southern England. Upperwings orange with brown margins and pale orange spots. Males have thick black line through centre of forewing. Underings have silver spots.
This rare skipper is restricted to chalk downs in southern England where it can be seen darting low over short turf, stopping frequently to bask on bare ground or feed on flowers such as Dwarf Thistle. It can be distinguished by the numerous silver-white spots on the undersides of the hind wings, which can be seen quite easily when it rests with wings in a characteristic 'half-open' posture.
The Silver-spotted Skipper has declined rapidly over the last 50 years but has re-expanded partially since 1980.
