Black and White Flower Fly - Melangyna

Black and White Flower Fly - Melangyna
Sitka County, Alaska, USA
It seems like this must be a flower fly (Syrphidae), but I'm hoping to do a little better than that, if possible. I am uncertain, but think the size is about 1cm, or so. Any help is appreciated, thanks.

Moved from Melangyna fisherii.

Moving back to genus for now since I'm not sure about the range of this one (it's not known from Alaska), and I did have not yet had additional confirmation of species id.


Following up...
Thanks for the help. I know its's kind of a long time since, but I was looking into this one a little more today and saw the range given on the guide page for this species indicates eastern North America - so wondering about whether we should consider this is an extension of the known range, or perhaps revisit? If I ever find one of these again, I'll try to get a collection for confirmation. Thanks!

Moved from Melangyna.

Looks like Melangyna fisherii
Looks like Melangyna fisherii to me - the spots on tergite 2 are large, nearly reaching the front of the tergite along its entire width and the sides for quite some distance. They look identical to Figure 143 in Vockeroth 1992.

Dead white to me is also a key for Ischyrosyrphus, but the relevant species would have round spots on tergite 2 (and the more southerly species would have the more rectangular patches extending 5/6 the length of tergite 2)

Yes, a syrphid.
You're posting some nice ones, Matt, but unfortunately they're not familiar to me.

Hey Ron
I think I remember seeing patterns similar to this in Eupeodes.

Good call, as always, Jon. Similar, but I don't see a match.
These stripes are almost dead white, as opposed as "towards ivory", not curved, and spaced a bit wider apart than the norm. Might well be a species we haven't seen posted - yet.
