Black and yellow mud dauber

The black and yellow mud dauber, Sceliphron caementarium, is a species of sphecid wasp. 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. Sceliphron caementarium can reach a length of 24–28 millimetres (0.94–1.10 in). Their petiole is black and is about half the length of the entire abdomen. The thorax shows various yellow markings, while the abdomen is normally black, with yellow propodeum (typical of females). The eyes are black, the antennae are black, and the legs are yellow with black trochanters and femurs. The wings are a tawny color.
