I found this female Organ Pipe Mud Dauber Wasp (Trypoxylon politum) building her nest under the porch roof during the 2006 AMSE Science camp. It is fun to listen to the buzzing wasps as they build their nests. She takes small balls of mud in her mouth to "daub" into rows, adding to the size of her nest. It can take up to 100 trips for a wasp to build a nest. After the wasp finishes the tube, she hunts spiders to bring back to the nest. She stings the spiders, paralyzing them, then stuffs them into the tubes. Next, she lays an egg on the spiders then seals them into a small chamber. This process is repeated several times. The wasp larvae eat the spiders, then pupate inside the tubes.
