query: Are mud dobbers a kind of paper wasps?
passage: Mud dauber
Mud dauber (or "mud wasp") is a name commonly applied to a number of wasps from either the family Sphecidae or Crabronidae that build their nests from mud. Mud daubers belong to different families and are variable in appearance. Most resemble long, slender wasps about 1 inch (25mm) in length.[1] The name refers to the nests that are made by the female wasps, which consist of mud molded into place by the wasp's mandibles. Mud daubers are not normally aggressive, but can become belligerent when threatened. Stings are uncommon.

They are both nest building social insects, but paper wasps and honey bees organize their colonies 
in very different ways. In a new study, researchers report that despite their differences, these insects 
rely on the same network of genes to guide their social behavior.The study appears in the Proceedings of the 
Royal Society B: Biological Sciences. Honey bees and paper wasps are separated by more than 100 million years of 
evolution, and there are striking differences in how they divvy up the work of maintaining a colony.
