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. Vespula species have a shorter oculomalar space (shown in the figure below right) and a more pronounced tendency to nest underground than Dolichovespula.
