I think it is an anthomyiid. Perhaps one of the many species in Canada of Eutrichota. How many post dorsocentrals has this specimen? |

Your photos are fantastic. I can see you have a Nikon camera. But which lens, flash and extra equipment, do you use? Best regards Anne Vibeke |

I count 2 presutural and 3 postsutural; can post larger view of thorax if needed. Thanks Anne. I will post some details and images of equipmet on Forums: The Lounge.

Thanks for the extra photo Tony. Appears to have a long prealar seta, which is what I expect. I will search through my material of Nearctic Eutrichota, but I only have about half of the species. As usual the male genitalia are probably critical to identify to species. These photos are indeed the best I have seen. |

Which orientation - dorsal, ventral, lateral, disarticulated? Anne - Check this thread and look at all the links: HERE Edited by Tony T on 20-04-2008 13:09 |

It is a male. You would probably have to dissect the abdomen, macerate it and photo it from various angles. In other words what I do to make a line drawing. Recently in Zootaxa there are some anthomyiid taxonomy papers, where the usual line drawings are now replaced with photographs taken with some complicated equipment and software probably similar to yours. If you send me your email address by private message and I will send you as an attachment an example of this technique. I would add that a photo of the apical half of the abdomen of a male anthomyiid taken from below (ventral view) would enable a lot of photos to be identified to genera. Unfortunately one can't do this with live flies. |

Unfortunately one can't do this with live flies. Fly is dry and hind legs prevent a pure ventral view. Was able to get a view from the posterior end- see below. Will now dissect genitalia for more detailed photo. Tony T attached the following image:  [180.22Kb] |

Probably Eutrichota cylindrica (Stein), one of our hairiest species. |

Thanks John, I will adjust the title. Just found an image of genitalia: Tony T attached the following image:  [53.42Kb] Edited by Tony T on 27-02-2015 14:39 |

The photo looks consistent with the illustration of E. cylinidrica. |
