Hello, Could this be Tachydromia umbrarum ? If useful I can provide detailed close-ups, the following pictures are heavily downsized to fit the forum requirements. Thank you very much for your help ! 18/5/2013, Vevey, Switzerland, on a wood fence in a little wood Size: 3.5 mm (body) Caillou attached the following image:  [38.37Kb] Edited by Caillou on 31-05-2013 19:52 |

Search the forum for T. umbrarum in ascending sequence - the oldest threads (e. g. http://www.dipter...ad_id=1999 plus http://www.dipter...ad_id=2026) explain a lot about the characters needed! There must be more than two scutellar bristles for instance. Regards, Sundew |

Thank you so much for your very informative answer ! You are obviously right : it is not T. umbrarum at all, sorry for not having looked for info enough; I usually search the most recent threads because I have seen cases where knowledge has progressed through time. I will have a look at all Tachydromia threads, from the oldest ones this time... |

So I have looked for further info, unfortunately I couldn't find anything I could relate to my specimen. Does somebody have any more idea ? Thanks anyway for the help so far ! |

Well, Paul Beuk is the one who knows best! Your photos are much better than mine (probably taken with an SLR?); may be, there are helpful characters visible. All my flies with banded wings remained "Tachydromia spec.", however... Genital structure might be decisive. You are right that newer threads might contain up-to-date information, but - the older ones are much more comprehensive, as the experts had much more time to deal with the photos in the early times of the forum. It is fascinating to read how the characters were discussed in depth. Now, understandably, with 2,652 forum members (luckily, not all active at once!), often just a name is dropped - to put the meat to the bones is our task then!

I am veeeeery reluctant to identify Tachydromia from photos since too many details are invisible. Too much chance for misidentification.

How could I not mention Igor as our great Hybotidist! (However, he had not been active in the forum for some time, so I did not notice his comeback - sorry for that.) Congrats to a species name! "Very probable" means you should label your pictures "Tachydromia cf. annulimana" to be on the safe side. |

Wonderful !! Thank you so much Igor for your verdict, I'm really happy by this outcome! @Paul: thank you very much too, I really appreciate that you would not commit yourself if you are not certain, this adds value to the cases where you deem it possible! Also my deep gratitude for providing this excellent web site! @Sundew: yes I completely understand that answers are usually very short nowadays out of necessity, and your advice of looking in older threads is very useful to keep in mind. BTW IMO your photos are quite good, I don't think mine are so much better but anyway I will PM you with my setup details - and no it is not an SLR... |
