this seems to be a Nematocera fly.  but if this is really Rhagionidae (and it fits!) how can be this be Brachycera? I mean: I have tought Nematocera with long abdomen and slender like this one, it hasn?t a stout abdomen as usual as we see in Brachycera... I know that in Nature there are greys... is this the case?  If Rhagionidae... is there in diptera.info any expert to say more about the fly.. genus level, at least?? I'm waiting for more opinions... Thanks Susan! |

This is Rhagionidae, genus Rhagio Fabricius. English common name, snipe fly. Jorge mentioned the long slender abdomen- the common name for this family is in reference to this feature. An easy way to tell Chrysopilus and Rhagio apart (if there is any question), is to examine the hind tibia. Chrysopilus has one hind tibial spur while Rhagio has two spurs. Cheers, Peter |
