It is a female
Eristalis, and this genus is tricky. For a certain identification, we should see the colour of legs and feet, the arrangement of hairs on the eyes (two bands or evenly distributed), and the face (is there a black stripe or not). In your case I dare a guess: the wings are hyaline without dark markings except the small pterostigma, and the latter is rather square, not elongated parallel to the surrounding veins. That points to
E. interrupta.
The key to
Eristalis can be found here:

P.S. The hoverflies have their own Syrphidae forum - post your threads there to meet the experts...
