''Polistes dorsalis'' (Fabricius, 1775) are a species of social wasps that can be found throughout various parts of North America.〔 It is classified under the Vespidae within the genus of ''Polistes''. Male ''Polistes dorsalis'' wasps can be distinguished from other ''Polistes'' species by their distinctly prominent median tubercle of sternum 7. Both sexes can also be recognized due to their v- shaped yellow markings on their head.〔 They are distributed widely across North America and can be found in sheltered nests, typically closer to the ground. These wasps live in a dominance hierarchy in which the queen’s role differs from that of ordinary workers. When threatened, these wasps can deliver powerful stings.〔 Their venom might also be of human interest for their antimicrobial uses. ==Taxonomy and phylogeny== A member of the Vespidae family, ''Polistes dorsalis'' is classified within Polistinae, one of the largest subfamilies consisting of a diverse group of social wasps. Under this subfamily, there are two behavioral groups that differ in their methods of colony formation and the presence of reproductive dominance. The first of these groups form colonies through swarming, as multiple foundresses initiate a nest. On the contrary, ''Polistes'' wasps are independent, and a nest is constructed by an individual or by a select number of female wasps. ''Polistes dorsalis'' are related to ''P. fuscatus'', ''P. metrics'', and ''P. carolina''.
