Trypoxylon
Same genus as the pipe organ mud dauber but not the same species. Most of our Trypoxylon nest in small cavities like this one. They use mud only for nest partitions and closures.

Nice find, great images.
Very nice series of images. While the wasps in this genus are solitary, they sometimes work in male-female pairs, the male guarding the nest against parasites while the female finds prey and gathers mud.
