Mud daubers construct nests of mud, especially on porches, decks, sheds, eaves, attics,
ceilings, walls and under roof overhangs around homes and other structures.
Solitary female builds nests out of moist mud containing several parallel cell rows.
A paralyzed spider is stuffed into each cell and one egg deposited on each spider.
The female then closes the cell opening with mud. Hatching larvae slowly consume the
spiders after which they pupate inside the cell.
