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!
Darren

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?

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.

Thank you so much! This all seems pretty conclusive.
