Moscow region, 22 june, 8-9mm.
It seems to me that it is not H. pluvialis?

Thank you Susan.
Well, in long absence of Theo we have to learn to ID Tabanidae ourself

With two different keys I came to H. crassicornis, having H. pluvialis to compare.
In addition I add image of male. I think it is H. crassicornis too...
