hi flyforum, Yesterday, I found a little bibio sp., size 5-6mm I try to find out if the antenne of this sp. is typical short or normal? I count 7 antenneparts, correct? The wing is transparant (on detailpicture 3 it is the flashlight what turns it milky) The wingstigma is dark, but you can see some darkness arround it (sharp or not-sharp?) I can use some help with it I think..

Hi Robert, I'm only responding because no one else is :-). My guess would be Bibio johannis. But just wait for the opinion of someone who knows anything about bibionids. Jan Willem van Zuijlen |

mmm...  Then I don't understand the issue in the key; - the shins are even as ligth as the femur... In this bibio, the femur are very dark.. The stigma should be braunish, that's what I can see (but also very dark braun) Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

Hi Cor, I'm not sure which key you are using, but it is obviously johannis: thorax and abdomen black haired stigma blackish tibiae reddish Theo |

hi Theo, Sorry for my misunderstanding, but I've read it often in the key and I don't understand?; I read in the key of 1997 (Zeegers), under point 16 that: Tibia are at least as light as the femur. The stigma of the wing is darkbraun > 17 17) B. Johannis in Dutch: Schenen minstens zo licht als de dijen. Vleugelstigma donkerbrun. greeting Robert, Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

Alright  That's very clear to me. I didn't doubt at your or Jan Willems expertise but I was mislead by other comments on my determination. Case closed 'problem' solved thanks Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |
