Rather more orange on abdomen than the Thelaira nigripes I'm used to - quite regular locally over the last month or two. I know this is an unreliable character so what about the ad bristles on tibia 2, I think I can just about see a ve as well? I guess it would help if I'd managed better photos! 29/7/2009; Devon, England. Thanks Tim tim worfolk attached the following image:  [184.08Kb] Edited by tim worfolk on 29-07-2009 16:48 |

Probably different fly. Same place, same time.

I think it's another T.nigripes - from the 2 long ad. The orange side patches are very variable in all species so they are hardly even a good secondary feature.  They are also (in my experience) much commoner than T.solivaga.

I agree, twice male Th. nigripes. Thelaira nigripes tends to be quite variable in abdominal pattern. Theo |

Thanks Theo. In fact abdominal pattern would appear to be so variable as to be useless. Tim |
