Syrphidae. Eristalinae. Probably Eristalis. Have a look at
http://www.canaco...stalis.htm
You may find a match among these.

Indeed Eristalis, one of the northern species which can be found in the Palearctic as well as in the Nearctic.
This looks like a female Eristalis fratercula, but from a picture it is not a 100% ID.

Thanks for the reply on my ID request. Any idea if the larva might be aquatic/semiaquatic?

Hello John,

It seems to me that the larva of Eristalis hoverflies of the genus are aquatic, feeding on decaying matter. The specialist opinion is preferable Wink
