Hi, I read there's one Bibio sp that lives in autumn in Holland. Could this be the one? Image taken today. Thanks, Andr Andre Jas attached the following image:  [64.85Kb] Edited by Andre Jas on 27-10-2006 23:49 |

What huge eyes! The head reminds me of Pipunculidae.

Actually, there are two autumn species, if you consider Bibio lepidus as a proper species (which I, at least for the time being, do): B. clavipes and B. lepidus. This would be B. lepidus: the pterostigma is large and dark. Good find ! Locality ? Theo Zeegers |

Just to be sure: could we see a closeup of the front tibia, please ? Theo |

Thanks. I misjudged the photo in first instance. It is not a Bibio, but a Dilophus. Most/all species of Dilophus have a large second (autumn-)generation, so opposed to the genus Bibio this is not special. Dilophus is recognized by short apical spines on tibia 1 and and additional row of spines halfway the tibia. Hardly possible to see in the picture, though. Dilophus febrilis is the only common species in most parts of Europe. Theo Zeegers |
