Just call me Mr. Mugu :-)

Guess it was wishful thinking on my part.

Weird "Ghost" of a (Satellite?) Fly in Image

Just noticed it, with head diving into the flowers...look below hind-legs of the female Eremnophila.
Miltogrammine flies like to trail these guys.

Could that be (a super-sonic) one?

Must be something close to

Thread-waisted Wasp - Eremnophila

if you want to start your search there, but Eric will likely know

Eremnophila aureonotata

Yes, these are Eremnophila aureonotata, a very common Thread-waisted wasp with no common name. There is only one North American species in the genus, and it is quite distinctive--all black except for the silver/gold marks. It is really more commonly seen than Ammophila, but for some reason has never been illustrated in any popular guides. Eric's new Kaufman guide, I'm sure, will have an illustration.

Very Unique & Interesting Post, Chris!!

Eremnophila are typically characterized by silvery-white patches of fine appressed hairs on the pronotal lobes, metapluera and elsewhere. Your image here is the best instance I could find (among the many Eremnophila posts on BugGuide) of the "rare exception" to this mentioned in Bohart & Menke(1). For more details, look under "Identification" on the BG info page (which I just spent many hours adding material to :-).
