D. norwegica is placed in the family Vespidae and the genus Dolichovespula. Based on recent studies on mitochondrial genes, Dolichovespula and Vespula are monophyletic, meaning they descended from common ancestors. Two species groups, maculata and norwegica, form the Dolichovespula clade. While the maculata has physical attributes such as pronotal striae, emarginated apices of the seventh metasomal sternum in males, and aedeagal medial lobes, D. norwegica females have long oculomalar space and lateroanterior clypeal angles with less prominent semicircular projections.
