Sceliphron, commonly known as the mud dauber wasp, is a species of solitary wasp found worldwide. They are medium-sized insects, typically measuring around 1-2 centimeters in length. Sceliphron constructs nests out of mud, which they use to house their larvae. They are known for their distinctive black and yellow coloration and their ability to capture and paralyze spiders as a food source for their offspring.
