Struggling with this one found on the south Devon coast on 2nd September. Keyed to Helina pertusa but most seem to have orange legs. Wondering if someone could put a name to it. Thanks
Thank you for the Helina confirmation. I was using Genus Helina Robineau-Desvoidy, 1830. After re-keying I think this fly is Helina reversio. Hopefully this fits in with your thinking.
