Hi Alex, for me It's a female of; Philipomyia aprica - Tabanidae.

Thank You Claudio !!!!

As already said in other posts, the difference between P. aprica and P. graeca is not so easy to detect. In this case I'd opt for P. graeca, obviously a female, but I have no solid evidence for it.

Hi Alex, with reference to:
KEY TO THE HORSE FLIES FAUNA OF CROATIA
(DIPTERA, TABANIDAE)
Stjepan Krčmar, Davorka K. Hackenberger, Branimir K. Hackenberger,
Periodicum Biologorum vol 113 suppl 2 2011, p 1-61,
the difference between P. aprica and P. graeca is the following:

1 3rd antennal segment with large pointed dorsal tooth, directed forward, orange-yellow in color. Apical segments darker.
Male antennae narrower, same color as female. Anterior three tergites yellowish-brown laterally with narrow median
black line. Abdomen is mostly covered with golden-yellow hairs. Halterae are yellowish. Facets always of the same
size in males. Male abdomen yellowish-brown on anterior three or four tergites with very narrow median black line often
intermittent on posterior margin of each tergite (Figure 249, 250, 251, 252, 253) ->
graeca (F.)
• 3rd antennal segment is dark reddish-brown with small rectangular dorsal tooth, not directly directed forward. Abdomen with anterior tergites rather dark chestnut brown with wide black median line. Halterae are brownish-yellow.
Males: all facets of almost the same size, 3rd antennal segment very narrow, generally darker than in females
with distinct small dorsal tooth, 1 st antennal segment – scapus mostly blackish-gray, abdomen rather narrow, same
color as in females (Figure 254, 255, 256, 257) ->
aprica (Meigen)

I always had great difficulties trying to choose between the two alternatives. Maybe a very detailed view of antennas could help a little more.
