So you caught 2 flies? While you keep them (are they dead now? let them dry and keep them dry), maybe you can make some extreme close-ups for us, the viewers? Please make a very close picture of the spines of the frontal tibia. And please a picture where we can see the color of the legs and of the hairs on abdomen and thorax (a good picture from the side will do).

The size is less then 10mm, now I count 7-8mm and with my magnifying glass I see a lot of hair on the thorax, on the first legg I see one strong/long (end)spine which is coloured (brown/red). Today I made one picture which is a little bit better then the first one, it was difficult to find one today. I saw a lot of them flying (~100) Tomorrow I make another picture (I hope better)

Definitely a Bibio spec.! Probably B. lepidus or B. clavipes. Both are autumn species. |

IMO they may just as well be the same species...

Congratulations again. I agree with Laurens: Bibio clavipes (or lepidus). IN agreement with my first ID. Theo Zeegers |

another viewon the front leg. Legs seems to be black!, the long strong spine on the frontal leg looks a little red/braun. This afternoon I brought the fly to the ZMA-lab, Theo can tell more soon I think. regards Robert Heemskerk,

Hi Robert, Your last posts removed all doubts: male Bibio clavipes. You can see * the terminal spine on tibia 1 (-> Bibio) * the typical slender base of femur 3 (-> clavipes or lepidus) * the stigma which does not enter the costal cell (9-> clavipes) Why are you so bothered about the black legs ? Legs are black in clavipes. Thanks Theo |
