Potter wasps have nests that look like ceramic jugs or pots. They create these mud nests on twigs, branches and the trunks of trees. The nest has only one chamber, unlike the many chambers inside a honeybee hive. They are most active during the summer.
A female will lay just one egg inside the chamber and then place paralyzed moth caterpillars inside it along with the egg before sealing the nest at the opening. The wasp larva will eat the caterpillars before making its way out of the nest.
