Silver-washed Fritillary Argynnis paphia

 

This is a woodland dweller, though like several other Fritillaries, it too requires Violets for the caterpillars. The strong-flying adults, which are on the wing from June to September, often feed at Brambles. Rarely in Somerset but more commonly in some other counties, a few females have a much darker greeny colouration and seem to favour more shaded woodland.
