Moved

black and yellow mud dauber, Sceliphron caementarium
Unmistakable, thanks. I was sure I'd scanned through the thread-waisted wasps as well, noticing none with such a long, narrow waist and certainly none with significant yellow, which took me back to the Vespids. I'll move these there, although they're of poorer quality than many and I wouldn't mind frassing them.

Mud dauber.
This is Sceliphron caementarium, the "black and yellow mud dauber," family Sphecidae (note the "thread-waisted" appearance).
