Brian sent us these shots of Brown Argus which he had seen mating in his garden in Harman’s Cross on 11 August, and gives us some useful tips for telling apart the male and female of this species.
The female is the one with the shorter wider abdomen, where the orange spots on the forewing go as far as the leading edge.
The male is the one with the longer narrower abdomen, and where the orange spots on the forewing do not go as far as the leading edge.
