I only got this top shot of a fritillary flying in shady conditions near the lane in Trentishoe Combe, Heddon Valley on 24th July. The National Trust walks leaflet said the area was favoured by high brown, whereas the dark green preferred the open bracken slopes above. There seems to be a slight inwards curve on the lower edge of the upper wing, but perhaps I'm imagining it
Are there any other diagnostic features I could look for? I've noticed that the 'hem-like' band at the edge of the inner wings looks more compressed on many dark green fritillary pictures, but I don't know if this is significant.
Any opinions much appreciated
James
