Caught in the East Sussex (UK) in early July this year. I caught 11 in total (in quick succession, at the same location) and the flies were ~12-15mm long Sorry for the awful photos (the fly has been frozen, and is attracting condensation at it thaws - but I really /need/ to keep it frozen) Is it possible to ID this to species from photos? What photos would be required in order to do so? Is there a key (preferably on-line, or in an on-line publication) that I could use to key it out? Thanks!

Having surfed the web a bit, I want to guess that this is a female Tabanus bromius. This is based on looking a photos, and the size/location, not on a key! What do people think? |

That's good to know  D - Thank you! Is there anything else you think it could be? |

The only similar (naked eyes, linear median callus and one eyeband) is maculicornis. Alula in form of narrow triangle = maculicornis, alula wide, almost rectangular = bromius. I believe I see wide alula = bromius. |

T. maculicornis is always much greyer (even slightly bluish), there is no doubt this is bromius. The feature mentioned by Libor is excellent, by the way. Theo |

Thank you so much! This all seems pretty conclusive. |
