Dolichovespula arenaria
Common Name:
The aerial yellowjacket.
D. arenaria is yellow and black. It can be differentiated from D. norvegicoides, the only other yellow and black wasp of the genus Dolichovespula in our area, by abdominal and genal markings. In D. arenaria the genal area is usually continuous yellow where as in D. norvegicoides it is interrupted by black. The posterior margin of the first (and sometimes second) gastral tergum of D. arenaria is broken by black medially. (In the picture of the abdomen shown here the second tergum is barely broken medially by black). In D. norvegicoides the posterior margins of terga one and two is continuous yellow.
