3 eye bands and hairy eyes = Hybomitra doesn't it Theo?

Shiny ocellar tubercle possibly a better diagnostic character for Hybomitra. Some Tabanus have hairy eyes and/or 3 eye bands.
Nice photos, someone should be able to make a positive ID.

Three bands and hairy eyes = Hybomitra is a rule of thumb, I give to explain that there is more than Tabanus.
Tony is right, Tabanus quatuornotatus is a notorious exception and in the Mediterrean REgion there are some more. NEvertheless, if you have 3 bands and hairy eyes, 99 % chance it's Hybomitra.

This one has a narrow frontal stripe and black notopleural lobes, therefore
female Hybomitra bimaculata

Black:
As my teacher said:
You can only learn by acknowledging your ignorance.
So don't apologize for it !

And I agree


Tony:
Things might be different in the new world.
