Hello flycatchers,
My first post on DI !
She was buzzing in my ears at work and I like to know who annoys me. OK for Dolichopodidae. Could it be a Dolichopus ungulatus ?
Note that the tip of the left wing is broken.

I do not see setae on hind tarsus. I'd say Hercostomus or Poecilobothrus sp., female.

Hello,
Thanks Igor.
What are the main criteria to separate these two genus ? I will look if I have other photos showing these points.
Regards,
Yann

Poecilobothrus has always purple spot on mesonotum laterally, Hercostomus - rarely.

Thank you. My other pictures show nothing better or very conclusive.
