Fly - Dasysyrphus - female

Fly - Dasysyrphus - Female
Sitka County, Alaska, USA
July 1, 2007
Size: ~1cm
The closest I find in the insect book I have is that it's probably in Syrphidae.

Moved from Dasysyrphus.

Either Dasysyrphus intrudens
Either Dasysyrphus intrudens species complex or D. venustus. I'm leaning towards the intrudens complex in this case, even though the maculae are more intermediate in shape than some flies here on BG.

The maculae on tergies 3-4 appear to reach the edge of the abdomen, maculae on tergite 2 are large, and n my opinion the maculae on 3+4 fit the description of the intrudens species complex (arcuate/lunulate, U/V shape on anterior edge, constricted in the middle, large swelling on medial edge) better than they fit venustus (venustus is described as the maculae being transverse, constricted slightly medially or not at all, medial edge swollen slightly).

However, at this point with this fly it's a judgment call; it could be venustus as well, though it feels more like intrudens species complex to me.

The shape of the yellow spots
The shape of the yellow spots give it away - it is a Dasysyrphus...
