Adult Natural History: The Eastern Yellowjacket can be found living in colonies. Colonies are made up of: queens, males, and workers. These colonies only occur during the spring, summer, and fall seasons. During the winter the queens are the only ones to survive the conditions. Every spring; each queen starts a new own colony.
In the spring, the females find a location to start their new colony. In rural areas almost all nests are in the ground. In uban areas nests are found in artificial cavities. These urban nests are called paper nests.
Distribution: This species is found in th Eastern United States and throughout the Great Plains.
