Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
The lines on the abdomen also differ based on caste, with the queens having one flared black line nearest the thorax followed by thinner black lines. Queens also have two black dots between each black line. [5] Individuals of this species range in size from 12.7–15.9 mm (0.5–0.625 in). [6] and weigh roughly 0.0014 oz (0.04 g). [7]

When another wasp attempts to land on an occupied perch site, the owner is alerted to the intruder. If the intruder does not fly away right away, then the owner will lunge and grapple the other wasp. Typically the two wasps will fight on the perch site and often fall off the site and land on the ground to finish fighting.
New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines).
