Fly - Eristalis anthophorina

Fly - Eristalis anthophorina
Sitka County, Alaska, USA
July 25, 2007
Any help identifying this fly would be appreciated. I hesitate to give a size, as I've proven myself to be pretty lousy at it, but this seemed like a relatively large fly, maybe between 1 and 2 cm long.

Fly - Eristalis anthophorina Fly - Eristalis anthophorina


I think this is anthophorina.
I think this is anthophorina....

Nice picture! It's for sure a male Eristalis sp. of the family Syrphidae.
Interesting is the long pilosity on the abdomen and thorax.
It seems to be a male Eristalis fratercula, which would be a new species for bugguide!

Now several years later I'm revisiting some things and I see E. fratercula is not currently known from Alaska, however there is Eristalis anthrophorinus (which maybe should be E. anthophorina) that has been collected in the same town I took this picture. Also, there is E. basilaris known from the region. and I wonder if either of these might be a plausible ID for the one in the picture?

Take a look at the photos her
Take a look at the photos here - it looks like E. fratercula should have pilose black on the sides of the abdomen, which I don't see on this lovely fly.

The only location data for E. basilaris that's on is from Georgia (the state, not the country) - odd that it would be in Alaska as well, but who knows?

I agree it does look more like E. anthophorina, but happy to defer to you. Nice find regardless!

Thanks for the help, I'm not any sort of an expert on flies, just doing what I can to learn to recognize the things that live around me. There are four collection records in the database for Alaska of E. basilaris, but all from 1954. The reference I use is the museum collection database - (here are results for Eristalis - they seem to include things that must have been formerly Eristalis.

There are some other Eristalis species known from the state that perhaps also occur in my region, but I'm not sure.

Maybe the apparently extra hairy nature of this particular one is due more to an artifact of the lighting?

I wonder if I should just go ahead and move it back to subgenus for now.
