Sceliphron curvatum, commonly known as the curved mud dauber wasp, is a species of solitary wasp belonging to the family Sphecidae. It is characterized by its slender body and distinctive curved abdomen. These wasps construct mud nests in sheltered locations, such as under eaves or in crevices, where they provision their larvae with paralyzed spiders as food. They are beneficial insects as they help control spider populations and are generally not aggressive towards humans.
