Arran brown - Erebia ligea


Arran brown undersde


Family: Satyridae

Flight Time: July - August

Size: 48-54mm

Altitude: 0-1800m

The Arran brown has a delightful white band across its underwing, which makes it easy to identify. They prefer relatively low altitudes, we saw them up to about 2000m in Switzerland, where both pictures were taken.

Named after the Isle of Arran, where they have reputedly been caught in the past, together with locations in Scotland. No modern evidence exists of any colonies in Scotland.

Two uppersides.
