I know this is a birdwatching site but any lepidopterists out there who could help me with this species. It was feeding on lavender in my garden in Newton, Porthcawl this afternoon. It’s either a high brown fritillary or a dark green fritillary ( not sure of sex). Unfortunately I didn’t get a pic of its underwing.

It’s one of those frits, you’re right…. why not post pictures on Facebook to South wales butterfly conservation group? Or the SEWBREC supporters page. Other butterfly groups are available. https://www.facebook.com/groups/1600501566838027
Hi Paul, I’ve sent sighting to Sewbrec with details. Going by location ie relatively close to areas of rough grassland/dunes and slight difference in wing markings I’d say it was the much commoner Dark Green, but there is a small localised colony of High browns not too far away, however they are ,apparently, very sedentary so unlikely to be a HBF. Thanks for advice and links. 👍
Acc to my research male Dark Greens and High Browns in partic are virtually impossible to isolate. The critical features are on the underwing it appears. John Wilson
Hopefully it’ll return and I can get a decent pic of its underwing.
