Organ Pipe Mud Dauber

 

It is easy to see how the Organ Pipe Mud Dauber got it's name. The mud nest of this specific solitary wasp does look kind of like a church pipe organ. The female wasp paralyzes it's prey(almost exclusively spiders) with a sting and carries it back to the nest where she deposits several spiders in a chamber then lays an egg in the chamber with the paralyzed spiders. When the egg hatches, the larva will feed on the spiders during it's development.
