This is indeed a member of the Eristalis genus. However, the species is unclear.
Eristalis are hard to separate.

To me it looks like Eristalis nemorum, due to the short stigma. But I've never seen a specimen of that species quite so dark in combination with such a distinctivly marked wing.

The species whom has these characteristics combined somewhat is Eristalis cryptarum. I have only seen collected specimens with pale spots on tergite two. Never with tergite two entirely dark. The arista should be short haired in E. cryptarum, unfortunately that is not visible on this photo.

Hope that helps,
