Found it in Northeast Nebraska hanging out on a plant on the edge of a tallgrass prairie and woodland while surveying for mycorhizal fungi. Thankfully I like taking pictures of wasps since I 100% thought this was a Polistes, otherwise I might have just walked on.

If anyone has any idea on an ID, it'd be much appreciated.

Does it look like these: bugguide.net/node/view/15985
Genus Paranthrene

An online resource devoted to North American insects, spiders and their kin, offering identification, images, and information.

That's also the taxon that I came to last night when I was trying to figure it out. Maybe! I have it up on bugguide too now.
Nice. Post a link when there is more confirmation! Great find and thanks for sharing!
Nothing on bugguide so far except confirming it's in Sesiidae. On my iNat record, I had a Sesiidae expert ID it as Vitacea polistiformis
