This one appears to show the characters of solivaga: an outer vertical (ve) and 4 decent length ad bristles on mid tibia, however it's less obvious on the left side. All the Thelaira at this site I've so far identified have been nigripes. I wonder what our Tachinidae experts think. 22/8/2009; Devon, England.

I find myself feeling that this one is pretty convincing but I still have a few nagging doubts so let's wait for Theo

Thanks both of you for the confirmation. It's interesting that both solivaga and nigripes occur at the same site, apparently even the same microhabitat. I've seen a lot of Thelaira here over the last few months but, as I say, everything positively identified so far has been nigripes. They seem to parasitise the same species (all those listed in Belshaw are common to abundant locally) so I wonder if their timing is different. Tim |
