Most likely Tabanus maculicornis, might still be bromius.

Hi Theo

Thanks again! Which detail do you need to see for separate Tabanus maculicornis from bromius? Is it possible to see the different details on pics which are taken in nature? There are more pics on my pc.

Best Regards, Brigitte

* a pic with the abdomen or thorax showing more natural colours, the first is unnaturally black-and-white (for a moment, I thought it was rectus !)
* a really sharp pic of the frons, either from front, aside or above
or
* a blowup of the wing base, for instance from pic 1 above.

* black and white:
all pics seems as this female has a high contrast in colour
Pic 1 shows the green leave near by in natural colour


* a really sharp pic of the frons, either from front, aside or above
really sharp I can't satisfy - send my best . . . Pic 2 and 3


* a blowup of the wing base
pic 4, left wing was damaged

Thanks a lot, Theo!

Best regards, Brigitte

Yes for maculicornis !

you can see
* onp ic 3 the bunch of black hairs beside the antennal base (if you know what to look for), nomen est omen !
* the very narrow alula in pic 4.

So no doubt, but unusually black-and-white she is

Very interesting! Thanks a lot Theo!

This female was in the shadow - perhaps the reason because she seems more black and white. I do have a pic with more sunshine: there is definitely more brownish to see.

Kind regards, Brigitte

Well, that does not help, since maculicornis is very distinctively bluish - greyish, definitely not brownish....
