Along with members of their sister genus [[https://en.wikipedia.org/wiki/Dolichovespula|Dolichovespula]], they are collectively known by the common name [[https://en.wikipedia.org/wiki/Yellow_jacket|yellow jackets]] (or yellow-jackets) in [[https://en.wikipedia.org/wiki/North_America|North America]]. Vespula species have a shorter malar space and a more pronounced tendency to nest underground, but are otherwise nearly indistinguishable from Dolichovespula.
