Dolichovespula is a small genus of social wasps distributed widely throughout the Northern Hemisphere. The yellow and black members of the genus are known by the common name yellowjackets in North America, such as Dolichovespula norwegica, along with members of their sister genus Vespula. In a study on the nesting biology of Dolichovespula, D. maculata was found to have the largest population count at 771.
A set of morphological differences distinguishes them from Vespula. The most noticeable is the long face (dolikhos = "long" in Greek). Viewed from the front, Dolichovespula faces are long, while Vespula faces are short and round. The oculo-malar space, the distance between the eye and the mandible, is long in Dolichovespula and short in Vespula.
Dolichovespula are not really a Yellowjacket, but pretty darn close, this wasp lives in wooded regions. The nests are constructed of a paper-like martial formed from chewed wood. This species constructs almost exclusively gray football-shaped aerial-nests attached to trees and buildings (but they may exceed a basketball in diameter or even the nest may grow to be larger by the end of the summer).
Dolichovespula nests are usually aerial, while Vespula often nest underground.
