Hi My first posting and just looking for an ID confirmation. This fly was photographed by a work colleague on the Black Isle just north of Inverness, Highland a couple of days ago. Is it possible to put a name or species to it. I assume it is a Tachinid. Regards Jimmy jimmy attached the following image:  [56.26Kb] Edited by jimmy on 07-08-2010 13:17 |

Looks like Dexiosoma caninum (possibly Dexia vacua maybe?) ... nice record but how on Earth did you get to Bacteromyia - did you key it?  Do you have any more photos from different angles? Also can you give me the full details (observer's name, date, location, Landranger map reference etc.) for the recording scheme? It's an unusual locality so will be good to have it logged

Hi I have been searching around and settled for Athrycia curvinervis. Am I correct? Regards Jimmy Jimmy wrote: Hi My first posting and just looking for an ID confirmation.

Way, way off ... sorry ... out of interest, what are you looking at to get the idea it might be Athrycia? This fly is a classic dexiine - long legs, wide gena, short antenna and it will have a plumose arista if we can make that out on the photo - probably too small.

Ah, OK so I looked at some pictures and thought hey that looks like it, I did not key it. I was expecting it to be distinctive enough to put a name too from the photograph. I have now looked at a picture of Dexiosoma caninum and it looks good. The other pictures I have are not great so I think we have stalled at this point. I think a specimen is required.

Thanks Jimmy ... sadly tachinids are very difficult for novices to identify from photos - you really have to know all the different alternatives and have a bit of experience with the group to attempt them. Specimens are much easier to work with and the British key is very good - and in the process of being revised ... by me

Thanks Chris I am often out and about so I will try for a specimen and even ask my colleague if he can get one from that same plant in his garden.
