These beautiful small butterflies are on the wing and in small colonies on the moor here in Rosedale. They are found on bilberry in a sunny spot with a bit of shelter from the breeze. Males are very territorial and perch on a prominent branch awaiting passing females. If disturbed they often return and settle on the same spot after a few frantic circuits. However, they can be hard to spot as they are well camouflaged against the green leaves of bilberry. Updale Natural History Recorder
