Vespula is a small genus of social wasps, widely distributed in the Northern Hemisphere. Along with members of their sister genus Dolichovespula, they are collectively known by the common name yellowjackets (or yellow jackets) in North America. The Vespula genus has a higher male paternity compared to Dolichovespula norwegica wasps.Vespula species have a shorter oculomalar space (shown in the figure below right) and a more pronounced tendency to nest underground than Dolichovespula.
