Polistes erythrocephalus is a species of paper wasp in the subfamily Polistinae of family Vespidae found in Central and South America. P. erythrocephalus is a eusocial wasp, meaning that it possesses both reproductive and non-reproductive castes. The cooperation between the two castes to raise young demonstrates the altruistic nature of these wasps. P. erythrocephalus exhibits a four-stage colony cycle, as do many other Polistes wasps. This species generally feeds on larvae, occasionally their own, and is preyed upon by species such as army ants.
Polistes scholars such as K. Yoshikawa, Joseph Charles Bequaert, and Mary Jane West-Eberhard, originally considered Polistes erythrocephalus to be a subspecies of Polistes canadensis. For this reason, much of the research done on P. erythrocephalus has been classified under P. canadensis. Additionally, it was left out of Yoshikawa's list of Polistes species around the world in 1963. More recently however P. erythrocephalus has been recognized as a separate species by Owain Richards though it is sometimes still referred to as Polistes canadensis erythrocephalus. Its closest relatives are Polistes canadensis, Polistes... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Red-Headed Paper Wasp is recorded against all the insects logged in Bastimentos Island National Marine Park (12 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
