Hello, could somebody tell from the photos which species I found? It was ailing (collision with car or bike?), sitting on a bikeway. Data: Germany, Lower Saxony, Rodenberg, ca. 70 m, 2 August 2020. Best wishes, Tina. Edited by Tina S on 05-08-2020 16:04 |

Female T. sudeticus. , our biggest horsefly. Might be a traffic casualty, indeed. Theo Edited by Zeegers on 06-08-2020 06:47 |

Hello Theo, thank you very much! The horsefly was very large, indeed. I'm struggling with the "brown eyes" Tabanus sudeticus should have. Are the eyes of my specimen only green due to light conditions (or the damage)? But they were green from all perspectives... Best regards, Tina. |

Yes, the difference is very subtle and also depends on light. In bovinus, it is all and only green. In your first pic, there are some bronze tints. Looking from above is the best way to get the bronze tint, also in Hybomitra. That said, the identification is straightforword based on antennal shape and colour. By far the best (ie. most reliable and easier to spot) feature ! Theo |

Hello Theo! In your first pic, there are some bronze tints. Your are right, I see it now.Looking from above is the best way to get the bronze tint That said, the identification is straightforword based on antennal shape and colour. By far the best (ie. most reliable and easier to spot) feature ! Thanks for this!Could you please explain or draw (or give me a link to) the antennal shape of our Tabanus species? Let's say, at least Tabanus sudetica and T. bovinus? Best wishes, Tina. |

Theo, a big thank you! It's a pity this apparently very detailed and deep work isn't written in English (but what are web translators for?). Nevertheless, the drawings are very helpful! Best regards, Tina. |
