Hello,

I photographed this fly in Bazzano (AQ), Italy, on May 29th 2019. I think it is a Tabanidae, but is it possible to identify the genus or species from these photos?

Thank you in advance,
Emanuele

Thank you very much Theo! I found it at about 600m a.s.l.

So, it looks like the male of H. caucasica (I know, weird name).
It is a bit lower than I'd expect, but that is a classic Winnie the Pooh argument
[I don't expect this species as this low altitude, hence it cannot be this species].

So I'd better rewrite my book of expectations

Thank you. All the photos I found online of H. caucasica show entirely black specimens, while this one has yellow hairs that cover its body. Is this difference due to intraspecific variability?

Yes, that is weird. The tibiae are slightly reddish as well. Disturbing.
If there are no additional pics, I am not sure.
Your golden hairs suggest auripila, but the palpus is white, not dark ?

Unfortunately I don't have other photos. H. auripila however, seems more plausible to me, and the palpus colouration in my opinion is not so different from the one of this specimen: https://diptera.i...pid=316201.

I disagree on the palpus colouration. This one is yellowish white, where the female you refer to has dark grey palpus. That said, I agree the identification as caucasica is troublesome, to say the least
