Is it possible to put a name on this fly, at least a family name, with this very general picture ? As identified on a French forum, the spider's name is Nigma walkenaeri (Dyctinidae). Thanks a lot !! pat_der2003 attached the following image:  [109.72Kb] Edited by pat_der2003 on 07-03-2011 20:02 |

Quite much demanded...Seems pretty small, so my bet is a male Eloceria delecta. Tachinidae anyways.

Male Eloceria would have yellow base of femur 3, so it is not Eloceria delecta. And Eriothrix would have tergites with discal bristles, so it is not Eriothrix. Hmm... should be some Musca...

Yeah, I am struggling to make this into a tach because I cannot see enough to be confident that I could attribute it to a genus or species ... to be honest I would probably just say that I am "data deficient"

Hmm... should be some Musca... Is the femur color a stable feature? The bend of the m-vein seems to steep for a muscid. There are some reddish-yellow rhinophorids as well, but the calyptrae are not really visible.. Edited by Jaakko on 09-03-2011 10:11 |

Well, at least distance between crossveins is extremly short in Eloceria delecta, not as in this specimen. Aphria without discal bristles, but I do not think it is Aphria, no strong bristles on tibiae, like in many Tachinidae. Rhinophoridae with reddish abdomen including tergite 5? I would vote for Musca...
