Partial albino 1625 Gatekeeper Pyronia tithonus (Linnaeus, 1771) - Horsenden West, Middlesex (VC 21), 30th July 2011 1
Description:

Seems quite close to the partial albino figured in Frohawk's Varition in the British Butterflies.
Does this form / aberation have a name (I could not find anything very close to it in the Cockayne collection (http://tinyurl.com/4yotsjs) although Pyronia tithonus britanniae ab. pallidemarginata is close(ish) but with even less orange - although this may be a photographic effect.

Based on a suggestion from another list this is a good match for Pyronia tithonus britanniae ab. pallidemarginata Oberthür, 1909
