Hello,
sorry, I have only this picture, taken from a distance. I first thought it was
Syrphus sp. (flying also yesterday), but the abdomen markings make me think of
Epistrophe grossulariae (?). Size about 8 mm, near forest (northwest Germany).

can at least the genus be confirmed?

Moin Jürgen,
it is with no doubt a female of Syrphus. In the field my predetermination would be torvus based on the broad black bands. In Northern Germany torvus was the most frequent Syrphus flying this April. Mid of April is a little bit early for Epistrophe grossulariae.
Regards
Piet

thank you!
In Northern Germany torvus was the most frequent Syrphus flying this April.
I also observed in former years, that
torvus (IDed by an expert from detailed photos of the eyes) was numerous here in spring.

Hi,
4 days ago I found this female with a similar colouration. But this seems to be clearly
S. ribesii (all yellow legs).

But this female is belonging to the genus Epistrophe.

now I am confused... :S My "
Epistrophe" turns out to be a
Syrphus and my "
Syrphus" to be an
Epistrophe.
