Today I found two flies, which are I think Aslilidae. I have no experience with this kind of flies. To be honest, I never saw one before. So I hope this is Asilidae sp.! And it would be great to know what specie this is  On the wing there was a little shining green/purple length: ~10 mm greetings Robert, Robert Heemskerk attached the following image:  [59.82Kb] Edited by Robert Heemskerk on 22-04-2006 00:21 |

I could have known this.. , I spent some time on these flies some days ago..In early spring this could be B. Johannis. I see a dark pterostigma, but is it black or brown..? The light hairs on the thorax makes me think of B. Lanigerus.. On another picture I can see clearly a big spine on the frontal leg, this means that it is a Bibio sp. anyway! On the frontal leg the metatars 3 = small and long, Bibio varipes could be the specie. Also the time of flying and the biotope (woodforest) fits.. I believe it is Bibio varipes But the legs of this male are not black?!, which I have seen on other pictures of B. Varipes.. greets, Robert

Difficult to see the pterostigma clearly but with pale hairs on the thorax and pale tibiae I would guess is is B.lanigerus. |

Hello Chris, Yesterday I found a mistake in my determination of this fly. For the metatarsers (3!) I looked to the wrong leg(it's the third leg and not the frontleg) That together with a dark pterostigma, whiite hairs, big red spines makes B. langerus a better candidate! Thanks again for your reaction |
