The black and yellow mud dauber, Sceliphron caementarium, is a species of sphecid wasp.There are some 30 other species of Sceliphron that occur throughout the world, though in appearance and habits they are quite similar to S. caementarium.
The black and yellow mud dauber, Sceliphron caementarium (Drury), is a common and widely distributed solitary sphecid wasp that hunts spiders and builds characteristic mud nests for their offspring (Figure 1). In each cell of her nest, a female mud dauber lays a single egg which she provisions with up to twenty-five live, paralyzed spiders.

The alarming yellow and black coloration on the Black and Yellow Mud Dauber causes many observers to slowly back away. While this wasp is certainly capable of stinging, it is not immediately interested in attacking people like other wasps.
Related Species: The blue mud dauber, Chalybion californicum Drury, is a metallic blue-black wasp of generally similar size and body form as the black and yellow mud dauber. It similarly hunts spiders to provision nest cells of the larvae but does not construct its own mud nest.

Mud dauber is a common name for a wasp that constructs its nest of mud. There are many species of wasps referred to as mud daubers, such as organpipe mud daubers, black-and-yellow mud daubers and blue mud daubers. Mud daubers are commonly found throughout the United States.
Mud daubers place paralyzed spiders in the nest cells as provisions for their young. Stinging the spider subdues the spider and also helps preserve it, so when the wasp larvae hatch, they have fresh meat. Black-and-yellow mud daubers prefer crab spiders and other small, colorful species. Organ pipe mud daubers also provide spiders for their young.
