Polistes canadensis
red paper wasp, Neotropical red paper wasp
Polistes canadensis is a primitively eusocial paper wasp native to the Neotropical region, recognized as the most widely distributed American species in its genus. Colonies are founded by groups of females in spring, with a single dominant queen and multiple foundresses averaging 9.1 individuals. The species exhibits a distinctive nesting strategy: rather than reusing combs, it continuously constructs new ones—averaging about 38 per colony—moving brood rearing to fresh structures as older combs are abandoned. This multiple-comb tactic functions as a defense against infestation by tineid moth larvae, which prey on wasp pupae. Workers display age-related task division (temporal polyethism), performing 22 distinct behavioral acts throughout their lives, with foraging typically beginning around the fifth week. Males adopt alternative mating strategies: territorial defense of landmark sites on ridgelines, or patrolling when territories are scarce. The species is notable for its confrontational dominance hierarchy, with queens aggressively suppressing subordinate reproduction through physical attacks rather than pheromonal control.
