Definitely Eupeodes, Metasyrphus

The knob on the face, seen in one image, is black.

The markings on tergite 2 may

The markings on tergite 2 may reach side margin but do not clearly overlap it. The markings on tergite2 are almost joined ( always clearly separated in Syrphus).
If the markings on tergite 2 were deemed to clearly overlap edges but not on tergite 3 and 4, it would point to Syrphus opinator but the bands are too wide, are not clearly separated on tergite 2 and the scutum not at all pruinose and it is not found in New Jersey.

In the East, the most common

In the East, the most common species is americanus... very likely to be this species

To me it looks like the yello

To me it looks like the yellow on T2 reaches the abdominal margin - do you disagree?

Looking

closely at the dorsal shots, it appears that the black margin may continue across T2, though quite narrowly at the anterior. But I do not get that impression from the lateral view. I believe the former would indicate Eupeodes. I do not find info on BG that indicates whether a discontinuous dark margin on T2 would indicate otherwise. Can you clarify? I added a photo that I'm not sure helps.

Some other members of Syrphin

Some other members of Syrphini have the yellow markings on T2 crossing the abdominal margin, while in Eupeodes they never do. Compare:

Eupeodes, dark margin on all of T2

Syrphus opinator, margin on T2 interrupted by pale marking (also true of other Syrphus, Parasyrphus, and some Epistrophe; Epistrophe with full bands on T3-4 have the pale marking reaching the margin on T2)
