Moscow region, 23 june. Small Tabanidae, 12-14mm, obviosly less than H. bimaculata. It act another way than H. bimaulata: do not fly to and fro, but attack immidetly (I have to lose some blood to make photo). Of course, collected afterwords without any pity I didn't find any 3-d eye, so I think it is small Tabanus. "Middle and low face spots" (sorry, don't know English terms) connected. Eye bare with one strip only - Tabanus maculicornis/bromius. Difficult to choise without flies to compare. I'd vote for T. maculicornis. Where is Theo?

Hmm - tricky - Stubbs says maculornis rather small and dark with very narrow alula and extensively orange antennae (females have some darkening on the antennae). Female abdominal pattern similar to T autumnalis. For T bromius he says females typically have orange flanks. Both of them seem to have the midway single eye stripe. T maculornis is apparently a much darker beast than T bromius. At only 10-12mm, T bromius is slightly smaller than T maculornis, and your specimen is more the size of T maculornis. I vote T maculornis too.
