Hi, any chance to specify this Bibio (I hope it is one) more exactly? Size approx. 7 mm. DE, Hessen, Gießen, broadleaved forest, 200 m, 25.04.2020. TIA Christian Christian Schulz attached the following image:  [172.87Kb] Edited by Christian Schulz on 29-04-2020 21:11 |

Hi Christian, Now this one is very promising. Very black, but small (as confirmed by the symmetrical fork in wing venation) Long antenna (for a Bibio). And if you look closely, light hairs on tergites. Very unusual combination of characters, I am thinking now B. ferruginatus, need to check the key. Theo |

Any other pictures available ? It is essential to be sure that the hairs on abdomen are light. If so, it keys out to the blacklegged form (f. atripes) of varipes, but I am not convinced. It looks very black. Theo |

Hi Theo, thanks a lot for your work! Unfortunately I haven't got pictures from a different angle, but I attach a max scale crop from the abdomen, maybe this will help a bit. Best Christian Christian Schulz attached the following image:  [242.06Kb] |
