The black and yellow mud dauber's nest comprises 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.
