Hello,
the last picture shows a female. And this specimen is no S. ribesii, because of the dark hind femur. Its a Syrvus torvus or a Syrphus vitripennis.

lweit, Gisela, thx for your help. Is there a way to separate S. torvus and vitripennis except by genitalia?

According to Tony Irwin S. vitripennis has bare eyes, which S. torvus doesn't have.
