Hello, is it possible to identify this Tabanus? I took the image in June in Northern Germany, the lenght was approximately 20 mm. Thanks and best wishes, Frank

I guess it is T. sudeticus female, but wait for Theo's confirmation.

I agree.

The antenna is pretty dark, though...

We have similar sudeticus in top part of the Bohemian Forest. With very dark antennae, one man identified them as T. bovinus and it was terrible for me understand, where is the problem. Strong dorsal tooth on 3rd antennal segment is evident...

As Libor correctly stated, some sudeticus ('' var. perplexus') can be remarkably similar to bovinus in most 'classic' features. However, bovinus
* has a less strong dorsal tooth
* eyes are stronger green alive
* abdomen is much more reddish at sides.

It practice, nearly if not all 'intermediates' are sudeticus.

Bovinus has become pretty rare in Central Europe and is restricted to chalky soils. Sudeticus prefers acid soils (bogs, etc...)
