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 |

|  Member Location: France Provence Posts: 1995 Joined: 06.02.08 | 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. |

|  Super Administrator Location: Netherlands Posts: 19403 Joined: 11.05.04 | I think the first one does not have darkened wings and, AFAIK, febrilis has completely dark legs in the female. Paul - - - - Paul Beuk on https://diptera.info |

| Member Location: Soest, NL Posts: 19203 Joined: 21.07.04 | 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 |

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 |

| Member Location: Switzerland Posts: 83 Joined: 03.05.07 | 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. |

|  Member Location: Paris (France) Posts: 1484 Joined: 21.04.05 | 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 |
