The Eastern yellow jacket or Eastern yellowjacket (Vespula maculifrons) is a wasp found in eastern North America and throughout the Great Plains region of the United States. This yellow jacket is a social insect, living in colonies of hundreds to thousands of individuals. Along with their subfamily, Vespinae, this species demonstrates supportive parental care for offspring, separation of reproductive and sterile castes, and overlapping generations. Their nests are usually in the ground and constructed out of papery material, giving the outside envelope the consistency of charred paper.
