MUD DAUBERS build small, tube-like nests of mud under
eaves, in attics and under the roofs of storage buildings.
Adult mud daubers are 3/4 to 1 inch long and vary from dull
black with bright yellow markings to blackish or blue-black.
They have longer, more slender waist than most other wasp.
As they develop in the mud tubes, young larvae are generally
fed spiders, including the poisonous brown recluse.
