The nest of a black and yellow mud dauber species Sceliphron caementarium is a simple, one, two or sometimes three celled, cigar-shaped mass that is attached to crevices, cracks and corners. Each cell contains one egg. Usually several cells are clumped together and covered in mud.
Sceliphron caementarium, also known as the yellow-legged mud-dauber wasp, black-and-yellow mud dauber (within the US), or black-waisted mud-dauber (outside of the US), is a species of sphecid wasp.
The mud dauber makes these nests for a good reason. Each one is filled with chambers, in which it will lay an egg, and for its offspring to feed when it hatches, it will provide a generous meal alongside the egg.
Many of our most common species such as the yellow and black mud daubers and organ-pipe mud daubers use spiders for prey, but other species use a variety of insects ranging from caterpillars to cockroaches to stock the nests.
The Mud-dauber Wasp is usually seen feeding on flower nectar but occasionally found flying with a spider held in its jaws, destined to be fed to larvae in a mud nest. Life history cycle. Normally the Mud-dauber Wasp puts several paralysed spiders in each nest with one egg, to eat when it hatches.
Sceliphron, also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and build nests made of mud.
The black and yellow mud dauber, Sceliphron caementarium (Drury), is a common and widely distributed solitary sphecid wasp that hunts spiders and builds characteristic mud nests for their offspring (Figure 1). In each cell of her nest, a female mud dauber lays a single egg which she provisions with up to twenty-five live, paralyzed spiders.
