Neotropical Red Paper Wasp

Polistes canadensis is a species of red paper wasp found in the Neotropical realm. It is a primitively eusocial wasp as a member of the subfamily Polistinae. A largely predatory species, it hunts for caterpillar meat to supply its colony, often supplementing its developing larvae with nectar. The most widely distributed American species of the genus Polistes, it colonizes multiple combs, which it rears year-round.

Emerging from hibernation in the spring, the females found nests built from plant material such as dry grass and dead wood. These nests are not covered with an envelope and feature hexagonal cells in which eggs are laid and larvae develop. The Polistes canadensis colony divides its colony among several combs and does not reuse these combs as a defense mechanism against parasites such as the tineid moth. On average, a single female queen with 9.1 foundresses usually initiates the construction of new combs and cells to form nests. The more foundresses in a colony, the more combs produced. On average, combs grow for 15.4 days and achieve a size of 30.8 cells.
