What Wasps Make Mud Nests?

Several species of wasps are known as mud daubers. These are solitary insects. They build nests made of mud. These nests are often located on buildings.

They are docile, non-aggressive, and often leave you alone. These wasps are about one inch long and have a black body with yellow markings. They are commonly found in the United States. They are not dangerous to humans but are considered to be a nuisance.

Mud dauber wasps build a nest made of mud tubes. These tubes can vary in color depending on the type of soil. They are commonly found on urban buildings. The nest is made by a single female wasp. The nests are made of mud that the female gathers by chewing and molding it into balls.

A female mud dauber lays an egg in a mud cell. Once it hatches, the larvae feed on prey left behind by the adult wasp. The larvae molt several times. Then they pupate in the nest chamber. The adults emerge in the early spring. These adult wasps die at the end of the year.

The mud dauber is a member of the genus Crabronidae, which is a family of wasps. There are several different species of mud dauber wasps, including the blue metallic mud dauber and the Sceliphron assimile. The blue mud dauber is found in the United States.

The Sceliphron assimile is found in Texas to Mexico. It has rectangular nests. It has yellow markings on its hind legs.
