wasp nest? - Auplopus

wasp nest? - Auplopus
Jim Thorpe, Carbon County, Pennsylvania, USA

Looks like some sort of mason or mud wasp or spider wasp nest-found under a rock. The rock was fairly tight on the ground. I was surprised to find this there.

Auplopus nests.
These are likely nests of one of the Auplopus (genus) spider wasps (family Pompilidae). But, the only way to be sure is to either hatch the remaining closed cells, or search that one empty cell for the remains of spiders (legs, etc). Pollen residue would indicate this is the nest of an Osmia mason bee. Caterpillar remains would indicate a wasp in the Eumeninae subfamily of Vespidae. Confused yet?:-)
