The mud dauber is a type of wasps that makes its nest out of mud. There are 3 species of mud daubers which all build their mud nest a little differently than the next. The organ-pipe mud dauber has a dull black color tone and makes elaborate nests with multiple mud tubes side-by-side that look like organ pipes. The black and yellow mud dauber has a black and yellow color tone that just makes simple one mud tube nests in crevices along buildings. Lastly, the blue mud dauber is metallic blue that makes a couple of mud tubes side-by-side, but not as elaborate as the organ-pipe mud dauber.
All 3 types are roughly the same size (1-2 inches) and have long, narrow waists which are one of its most recognizable features. Mud daubers will use the same nest site each year if possible. However, other wasps and bees do make a home out of vacant mud tubes. Like mining bees, they are also solitary wasps that don’t live in large colonies. They also do feed on nectar, but primarily prey on smaller insects like spiders.
