Just over 2 hours wandering around the the lower NW slopes of Arnside Knott adjacent Copridding Wood produced 15 species of butterfly. The highlight were two duelling fritillaries, which, when they settled proved to be a male Silver-washed Fritillary (my first in the Arnside and Silverdale AONB) and a High Brown Fritillary (at SD 44632 77232).
