Last week the question was: What is this?
This is a potter wasp nest. This nest is made of mud, similar to mud dauber nest. Potter wasps are in the family Vespidae, which is different from the mud dauber (Sphecidae). Potter wasp nests are not normally as noticable as mud dauber nests because they are frequently made hidden on the branches of plants, like this one that was made on a small branch in a shrub. Below is what the adult looks like.
