Helle Koenraad,

This is indeed E. balteatus. It looks like an intersex specimen. Having incomplete male genitalia and the eyes seperated, but not as much as a normal developed female. There is somwhere on diptera.info a very extensive thread about this phenomena in E. balteatus.

Greetings,

Ectemnius

Thank you, Ectemnius.
I will check the thread, since the phenomenon is new to me.
