Hi, could that be Bibio johannis? Found on May 23, 21 in Germany, North Bavaria, on a meadow. Estimated size 6-8 mm. Thanks and Regards, Eugen Eugen attached the following image:  [142.5Kb] Edited by Eugen on 29-05-2021 17:41 |

Hi Eugen, this is most probably a female Bibio rufipes: - Wings brownish - Thorax sides partly red - Abdomen ventrally yellow Greetings, Eric |

Don't you expect them to be here (I'm in Franken, Northern Bavaria, too, and they are quite common here).
Greetings, Eric |

Schacht in his checklist for Bayern does not mention this species https://www.zobodat.at/pdf/ENT_0018_0549-0555.pdf According to fauna-eu, it is strictly boreal https://fauna-eu.org/cdm_dataportal/taxon/b25f05f0-a877-43e5-99bf-e4282ec7138b and johannis often has very red legs .... So unless you are 1000 % sure and you have males as well, rufipes seems unlikely Theo |

Hi Theo and thanks for the Schacht-pdf. I will check my females, males and couples - of which I think they are rufipes - again as accurately as possible and come back with the analysis asap.
Greetings, Eric |

That would be great. Of course, I cannot comment on specimens I haven’t seen, but it needs to be double checked. Thanks Theo |

I disregard female Bibio, so I shouldn’t comment, but I am convinced you are right, Libor. johannis can have totally red legs. Theo Edited by Zeegers on 01-06-2021 07:54 |

I've looked again at the images and on #1 I think I can see the V-shaped callus on the frons which should be significant for the female rufipes (Bibionidae de la faune Belge, Jan Verbeke). If you compare this snippet with your original photo you may see it more clearly. Eric eklans attached the following image:  [143.17Kb] |

Hi together, thank you very much for your effort. I have attached an enlarged section again. Unfortunately, it doesn't get any better. Greetings Eugen Eugen attached the following image:  [84.5Kb] |
