Polybia sericea is a social, tropical wasp of the family Vespidae that can be found in South America. It founds its colonies by swarming migrations, and feeds on nectar and arthropods. P. sericea is medium in size, and has a dark-colored body. The wasps build multitiered nests, and colony size can vary greatly between a few to a few thousand workers. Queens can be distinguished from workers by their greater body size and smaller head size. They tend to be polygynous, meaning that several egg-laying queens are within a nest, with the result that workers are generally less related to each other than in other eusocial species. Workers are responsible for hunting and foraging, while queens are responsible for laying eggs, and have the most developed ovaries. When hunting for prey, workers rely heavily on visual and olfactory cues. Prey include arthropods such as green and brown caterpillars.
P. sericea is a species within the genus Polybia of the subfamily Polistinae. Polybia is the most diversified genus within tribe Epiponini, which is characterized by colony founding via swarming. Placement of Polybia among related genera has fluctuated, and the genus may... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Polybia sericea is recorded against all the insects logged in Fortaleza (11 verified sightings), 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.
