The Mud Dauber is a wasp that makes mud nests that you see in the corners of the walls and roof lines. In July the mud dauber wasp make nests of mud cells. In the cell the wasp lays an egg. She will then collect several spiders that she stings and places in the cell. The egg will hatch into a larva feeding on the spiders before hatching.
The mud dauber wasp likes to make its home in elevated areas, but unlike many of its social wasp relatives, this wasp constructs nests from mud. The female mud dauber wasp rolls mud into a ball and transports it to a typically dry, high place to build its home. With the mud dauber wasps we again see a tendency of this wasp to build its habitats near homes and other man-made structures.
The nest itself tends to be smaller in scope compared to other colony-based wasp nests, but can still protrude greatly from the sides of buildings. Nests are most easily identified by their cracked/dried mud texture, as well as the many holes burrowed into the sides of the structure. Some species of the dauber create nests that appear similar to organ pipes, with multiple cylindrical structures parallel to one another. Others construct mound-like structures, with rounded tops and flat bottoms where it is attached to the building or residence.
The mud dauber wasp does not typically search out for human food like other wasp species do. Instead they feed on local insects, primarily spiders. This is one of the reasons mud dauber wasps are considered not a serious threat to nearby humans, and are even sometimes seen as helpful. During the process of building her nest, the female mud dauber wasp captures and paralyzes many types of insects and spiders, bringing them back for her eggs to eat upon hatching. Once hatched these wasps prefer to hunt for similar food, stinging and paralyzing spiders rather than searching through our garbage for leftovers.
Mud dauber wasps have thin, elongated black bodies and wings about the size of their body. They also have a somewhat bulbous stinger and large, arching hind legs. Most are black with bluish or grayish markings, but other subspecies can be seen with yellow streaks along the legs and bodies
Mud dauber wasps are typically non-aggressive species of wasp, with almost no documented cases of stings. Even in known incidents of nest-destruction, the mud dauber wasp remains relatively calm and relocates quickly rather than attack the destroyer. Despite this fact caution should still be used when dealing with a mud dauber wasp nest, as their sting may cause swelling, pain and redness.
