Northern Germany, Schleswig-Holstein, Pinneberg-Waldenau near Hamburg, at the edge of the mixed forest Klövensteen, at a leaf of Stinging nettle; Outsidephotos: kuv, 16th of October 2017. Perhaps Bibio clavipes? Is my idea ok? Please help to get the ID and whether male or female. Kuv kuv attached the following image:  [87.04Kb] Edited by kuv on 17-11-2018 17:40 |

First, we cannot see the tip of the front tibiae, which is needed to discriminate between Bibio and Dilophus. In Bibio, the front tibiae end in a pair of large spurs, in Dilophus there is a circlet of small spines. However, the males of the frequent D. febrilis do not have such swollen hind tibiae and tarsi. So it might be a Bibio indeed. There are two autums species, B. longipes and B. clavipes (see https://www.flick...177500145/). B. clavipes has a rather pale stigma that does not extend into the tip of the costal cell; I saw it in Brandenburg recently. In your case, I would vote for B. longipes. Maybe Theo can say more. Regards, Sundew |

In males Dilophus, the hind metatarsus is slender. So I agree with Sundew, most likely Bibio longips for the reasons given by her. But I am not dead sure Theo |
