Vespula


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 in North America. Vespula species have a shorter oculomalar space and a more pronounced tendency to nest underground than Dolichovespula.
