Perhaps Dilophus femoratus? |

No, this is one of the other Dilophus species, as this female does not have darkened wings.

Stop. First of all, D. femoratus has (nearly) clear wings. It is febrilis, that has darkened wings. Second, my guess is that the first specimen has darkened wings -> febrilis Thirdly, the second one does not, so it is another species and thus another specimen(right ?) femoratus-group, possibly femoratus Theo |

Yes theo, you are right, I made an error in this post by putting these two different specimens. Moreover the second is really bigger than the first one, approximately 5 mm. Thank Theo for the the precision. |

I think the first one does not have darkened wings and, AFAIK, febrilis has completely dark legs in the female.

Leg coloration tends to be very variable in many Bibionidae (though agreed, not all). The wing is distinctly darkened, so it really must be febrilis. I'll check my collection Theo |

so, I did, and I must say, Paul has a point. IN all my females febrilis, the front (and other) legs are black, whereas in all femoratus they are clearly reddish. So looks like it is femoratus, in which case I have been fooled in the wing colouration (ie. it is not darkened). Theo |

Sorry, but first specimen is neither febrilis, which has always entirely black legs and dark abdomen, nor femoratus which has milky white wings. I would incline for antipedalis : the female has more or less darkened wing membrane, anterior femora and coxa rufous yellow, a transverse row of large spines on anterior tibia and abdominal sternites clearly lighter than tergites. D. antipedalis is a west-mediterranean species (and this specimen was apparently photographed in Provence). The second specimen is not recognizable in my opinion because of the poor quality of the picture. |

What more do you need? Unless you have specimens I guess there will be no change in ID's

Colobo, According to Fauna Europaea, D. antipedalis is only present in Spain mainland, Portugal, Sardinia, Balearic is. For one time, the territory seems coherent (this is not always the case). I know that Christoophe lives in the south, but not so far away. Edited by pierred on 16-07-2009 18:04 Pierre Duhem |
