Teesmouth Bird Club

Apologies for posting a non-bird sighting to this page but it seemed like the best chance of a clear answer.  Photographed a very faded, slightly tattered fritillary of some kind today, near Malham in Yorkshire.  Thanks to the aforementioned damage, I'm struggling to identify the species with any confidence, although the antennae seem to be a good match for dark green fritillary.  Any thoughts or opinions will be gratefully received.

It is a Dark Green Fritillary.

Thanks for the confirmation.
