Black and yellow mud dauber is a common name for the sphecid wasp species "Sceliphron caementarium". They are solitary insects that build nests out of mud in sheltered locations, frequently on man-made structures such as bridges, barns, open porches or under the eaves of houses. These nests are not aggressively defended, and stings are rare cite journal |quotes=np |author=L.

The black and yellow mud dauber's nest is comprised of a series of cylindrical cells that are plastered over to form a smooth nest that may attain nearly the size of a human fist. After building a cell, the female wasp captures several spiders. The captured prey are stung and paralyzed before being placed in the nest, and then a single egg is deposited on the prey within each cell. The wasp then seals the cell with mud. After finishing a series of cells, she leaves and does not return. Eventually, the hatching larva will eat the prey and emerge from the nest. A common species of cuckoo wasp, "Chrysis angolensis", is frequently a cleptoparasite in "Sceliphron" nests, and is only one of many different insects that parasitize these mud daubers .

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". "S. caementarium" is widespread in Canada, the United States, Central America and the West Indies, and has been introduced to many Pacific Islands (including Australia, Hawaii and Japan), Peru and Europe [cite book |url=http://www.answers.com/topic/mud-dauber-wasp?cat=technology |chapter=Mud dauber wasp |title=Grzimek's Animal Life Encyclopedia] , where it has become established in the western Mediterranean Basin [cite journal |quotes=no |title=Further evidence of the Asian mud-daubing wasps in Europe (Hymenoptera: Sphecidae) |author=A.
