Three genera: Sceliphron, Trypoxylon, and Chalybion

Mud daubers are among the most familiar solitary wasps. They belong to a number of related groups, but we call them all "mud daubers" because they all build their nests out of mud. One way to tell the different mud daubers apart is by the distinctive architecture they use.
