1 September 2007, NB, Canada. Length: 7.5mm Seems too small for a Calliphorid, also could not see any setae on meron. EDIT: I looked through the gallery and saw Nikita's image of Eudasyphora cyanicolor a species that occurs in NA; could this be the same species?

Hi Tony. Small and all-metallic looks more like Pyrellia. Also Neomyia may have not sharply curved M (N.nudissima). Eudasyphora has setae on R1 ventraly. Has it yours? Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Thanks Nikita. Superimposed setae on base of wing (scanned from a book) that closely resembles my fly. Setae are larger than actual but position is accurate. Tony T attached the following image:  [45.11Kb] |

Yes Tony. I think that 3 short setae on radial node is ok, but I don't understand what 2 long setae out of wing membraine means. I regard its as some "artefact" (if not - I have no idea so far) In this case - It isn't Eudasyphora without setae on R1 Neomyia has this setae till crossvein and usually sharply curved M So, really looks like Pyrellia for me...

Thanks Nikita. My drawing is inaccurate, those 2 setae actually arise at the extreme lower border of the vein and not from the membrane. Seems that there is 1 sp. in NA (Pyrellia cadaverina), 1 sp. of Neomyia (cornicina) and 3 spp. of Eudasyphora of which 1 (cyanicolor Zetterstedt) was originally described as a Pyrellia. |

N.cornicina has prst ac, your fly hasn't. Fits ok with Pyrellia cadaverina Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Pyrellia should have only one postsut. intra-alar, no ? I can see 2 ia here. Thus, R1 setulose + 2 ia -> Eudasyphora ?

You are right Stephane, 2 post ia. But in this case R4+5 has to be setulose till crossvein as in attached image. Tony, please, check the wing again, setae on R4+5 may be not easy visible.

Tony, please, check the wing again, setae on R4+5 may be not easy visible. Nikita Sorry to have caused so much discussion, just wish I could reciprocate by helping with Palaearctic flies. This specimen has setae on both dorsal and ventral surfaces of that vein almost all the way to the cross vein. I think you can see both sets of setae on the enlargemenrt of the dorsal wing. Also including, for my future reference, an enlargement of the thorax to show the 2 postsutural intralar setae (and their shadows). Tony T attached the following image:  [105.73Kb] |

Don't be sorry Tony, I think this kind of discussion is very instructive. Your photos would be deserving of figuring in a good book on Muscidae ! In conclusion, I think we can say Eudasyphora. Stephane. |

I think that would be a good idea to create a special section called STICKY threads.. for those that have very interesting posts like this one! |
