Hello. It looks like Tabanus quatuornotatus, but I don't sure. Do you have more angles?

Actually Tabanus spp. of quatuornotatus group have hairy eyes too. My doubts was exactly about the pubescense of the eyesWink Shape of the frontal calli and polished subcallus strongly suggests T. quatuornotatus (see here http://www.dipter...to_id=3393).

Seregiy, I think only two possibilities are on the table: (1) Eyes are haired, so T. quatuornotatus (no other species of this group in central Italy has three big black calli and polishes subcallus. (2) Flesh and light are playing any game with us, then eyes naked = T. glaucopis.
So, Justafly, can you enlarge pic of the right eye to see if the eyes are naked or haired.

eyes clearly haired - this is a female of Tabanus quatuornotatus.
> lower callus squared and dull black
> subcallus polished black
> 3 band eyes
> hairy eyes

My last 2 for the moment am I ok with im Saftflu├č einer Ro├čkastanie - from the sap of a horse chestnut schl├╝pfte - emerged?

Thank very much Paul it is very helpful to know these words

03.06.16 16:52
Hinterleib -> abdomen; Ring -> Segment, because strictly speaking it is the tergite and sternite that form the ring.

03.06.16 12:10
Another couple of old words which I would be grateful for help on Hinterleib narrow, light grey with a pair of small rounded spots on Ring 2 and 3, 4th Ring ungefleckt Hinterleib- ? Ring - terga?

23.05.16 12:37
in fact I prefer Schwinger to halteren

23.05.16 12:37
Thx very much Paul

23.05.16 09:12
Yup, Schwinger is halter, a yellow halter in this case. Smile

21.05.16 12:32
Can anyone help out with the German word Schwinger gelb - is this an old word for Haltere?
