Hello, this tabanidae is from last july from switzerland. Lenght was about 12mm. Can anything be said about it? Genus perhaps? Thanks, Michael Michael Becker attached the following image:  [87.51Kb] Edited by Michael Becker on 24-02-2011 10:53 |

It is certainly a female Hybomitra and very likely, it is H. montana Theo |

Why not H. bimaculata, Theo? Too dark antennae? Libor |

Yes, Libor, the antenna is very dark indeed and seems pretty slender, the frons seems to be parallel-edged (but, I admit, difficult to judge) and the reddish sidemarks are too small for bimaculata (in general). A very nice feature of the montana-groups versus bimaculata-group is that the eye colour in living material is much more vivid green in montana, as nicely shown in this picture. Excellent feature in living material ! You might be bothered by the dark notopleural lobes, this is indeed unusual for lowland montana but pretty common in mountain-montana. But, I agree, montana is by no means sure. Theo |

Thank you for your answers and for the explanation. But what are the notopleural lobes? Michael |
