Hello all,

Would it be possible to identify this female Syrphidae? (Genus, Species)?

Those pictures were taken in a marsh near home (Quebec, near Vermont).

Hello,

here in Europe this would be an Eristalis tenax female. The species is distributed worldwide, but I don't know if there are additional similar species in North America.
Best regards,
Jürgen

Thanks! I think the hairy bands on the eyes are distinctive enough to say it's E. tenax.

Interesting, that E. interrupta is listed as 'uncommon' for Ontario. Here it is one of the most numerous Eristalis, more abundant than arbustorum, which listed as 'common and widespread' for Ontario. But both species are nearly ubiquitous here and live in the same habitats.
Best regards,
Jürgen

Thanks a lot John and Juergen for your so appreciated help.

Others (from others forums) pointed me toward E. tenax.

Cheers,

Michel
