High Brown Fritillary (left) and Dark Green Fritillary (right). The upperwing pattern is very similar and it is almost impossible to tell the two species apart from the upperwing.
High Brown Fritillary (left) and Dark Green Fritillary (right). The underwing pattern is quite different and is diagnostic. To seperate these two species you really need to see the underwing. Note especially the brown spots with white centres towards the rear of the wing which is diagnostic of High Brown, and the extensive area of green on the lower wing of Dark Green.
High Brown Fritillary is a rare and localised butterfly in the UK, whereas Dark Green is much commoner and can occur as far north as northern Scotland, where I have seen them at Loch Sionascaig, Inverpolly.
I find photographing fritillaries quite difficult, but if you can find an area where they are feeding, you can get very close, and in fact they seem almost drunk with nectar and oblivious to your presence.
