Butterfly Aberation.

Occasionally aberant forms of common butterflies turn up, and I was lucky enough to see one on the Broncham Hill section of the Ridgeway at the weekend. I was very puzzled at first as it was unlike any of the  Dorset species normally seen, but its size and behaviour hinted that it might be some form of Small Copper, and so it turned out to be. Devoid of the normal coppery red colour, this is the rare aberant albino form, Lycaena phlaeas alba.
