Aerial yellowjackets, make their paper nests in branches of trees, bushes, house eaves, or other places in the open air. They are considered beneficial because they only feed on insects. They can help control flies and other harmful insects like caterpillars and aphids. They can sometimes be confused with paper wasps, which are a less annoying species.
One of the most common wasps in North America. Nest construction begins in March with most colonies dying out by July. Nests are usually above ground ranging from a few inches up to the tops of trees. Colonies can also be found in or on man-made structures such as sheds, houses, garages, etc. The number of workers in an active colony at any one time can be as high as 700. Adults tend to be less aggressive than most other species of yellow jackets, although when aroused they have been known to spray venom out of the sting.
Adult Activity Period: March – July
