Wasp - What's going on here? - Campsomeris plumipes - Male
Ashtabula County, Ohio, USA

I'd love to know what this wasp is, and what's going on in this shot. There are 2 or 3 yellow/orange things on it's leg.

Moved from Campsomeris.

Moved from Scoliid Wasps.

Wasp ID
Cool photo.
The wasp is definitely a scoliid male. Based on the locality and general appearance, I think it is Campsomeris plumipes.

Thanks everyone!

This is so cool--I'm most grateful for all the expert input!

Milkweed pollinia
They look like the pollinia (pollen sacs) of milkweed. I have seen many insects, from bumblebees to ladybugs, with them hanging from their feet. You can see one example in this page

I agree.
I agree, the sacs are from milkweed. I have even seen dead honey bees on milkweed flowers that became hopelessly entangled in those sticky things. Oh, the wasp is a male scoliid, by the way:-)

? Orchid Pollen sacs
These look like pollen sacs of orchids; the wasp stuck its body into an orchid flower and the orchid somehow clamps the pollen sacs onto the legs. When the wasp visits another orchid the pollen is transferred. I think maybe other plants use a similar mechanism, ?milkweed.
