Mud daubers are slender, long-waisted wasps that are usually black or metallic blue (sometimes with yellow markings). In Central Virginia, the easiest way to identify them is by their nest: they build small tubes or clumps of dried mud on sheltered surfaces like under eaves, porch ceilings, garages, sheds, and attic entrances. They’re solitary (don’t live in colonies) and are usually not aggressive, but their nests often appear where people and pets pass by and stings can occur when the nest is disturbed.

Mud Dauber Behavior
The Mud Dauber is unique. Especially when it comes to raising their young. The female mud dauber will leave the nest to hunt spiders. Upon finding a spider, she will sting and paralyze it. Afterward, she will drag the spider to her nest and place it inside one of the mud chambers. The female then lays an egg on the spider and seals the chamber shut.
When the egg hatches, the baby was (larva) eats the spider. The larva will molt several times and become a pupa. Then eventually will transform into an adult wasp. Once an adult, the wasp will leave the nest. When they dig themselves out, they leave small round holes in the side of the nest. Then they repeat the process.
