Hallo Team,

Viele Grüße,
Klaus

Neither. It is bromius, please obserne the eye band. Sudeticus is much much bigger.

Did you really measure it ? It is 15mm., not 23mm.

Hallo Theo,
my answer
a.) The length of my fly has been estimated to be 23 mm from head to wingtip
b.) In the eye you can see a bandage at high magnification. ( see photo)
c.) Tabanus bromius --> length 11,5 mm bis 19,5 mm (Wikipedia)

Theo, is the name Tabanus bromius??

Viele Grüße,
Klaus

Yes, it is the female of bromius. The other species don’t have eye bands. You must have overestimated its length, this often happens in living specimens.
