See this image for a collection of commonly seen wasp nests:
The presence of a pollen mass inside indicates that a nest belongs to a bee or much less likely Pseudomasaris:

Note, both of the families Crabronidae and Sphecidae and subfamily Eumeninae may have similar-looking nests, built with mud or pottery and also might have a preference for provisioning certain spider types, larvae, bugs, flies, bees, beetles or other arthropods.
Since they may have similar nests, we will place all of the unidentified images here, awaiting any further evaluation by the experts.
