Shibden Valley

Gatekeeper. Only one 'pupil' in the forewing eye-spot is visible. But the butterfly was clearly smaller than Meadow Brown, and the underside of its hindwing is typical Gatekeeper: in particular Thomas and Lewington (2010) point out that on Gatekeeper its tiny spots are white, whereas on M brown they are black.
