Identification
key to the 11 northeastern spp.(1)
Large social wasps with long legs, usually brown, yellow markings typically less extensive than yellow jackets and hornets (Vespinae). Build distinctive paper nests attached to a surface by a stalk. No outer covering of cells as in the Vespinae.
Males have curly antennae and yellow faces (P. annularis males have red faces just like females).

Range
worldwide
Season
Early spring to late fall (in warm areas year-round). Only workers early in season--males are going to appear late summer to fall (earlier in the south). Females overwinter, in P. annularis also males.
Food
Take nectar and juice from ripe fruit. Predatory on other insects (predominantly caterpillars) to feed larvae.
Life Cycle
Semi-social wasps, all females are potential breeders. Fertilized queens overwinter in crevices or under bark. In spring they build a nest and the colony builds up over the summer. At first, only workers (sterile females) are produced. Mature colonies have up to 30 adults. A young queen is the sole survivor of the colony.
Larvae:
Remarks
Not as aggressive as Hornets or Yellowjackets. Often build nests under eaves. May be considered beneficial to gardeners (feed on herbivorous insects).
Parasitoids include Pachysomoides (Ichneumonidae)
