Chalybion californicum, the Nearctic blue mud-dauber wasp or common blue mud-dauber wasp of North America, is a metallic blue species of mud dauber wasp formally described by Henri Louis Frédéric de Saussure in 1867. It is not normally aggressive towards humans. It is similar in shape and color to the steel-blue cricket hunter (Chlorion aerarium). Like other types of wasps, males do not have an ovipositor, and therefore cannot sting.
