Polybia occidentalis, commonly known as camoati, is a swarm-founding advanced eusocial wasp. Swarm-founding means that a swarm of these wasps find a nesting site and build the nest together. This species can be found in Central and South America. P. occidentalis preys on nectar, insects, and carbohydrate sources, while birds and ants prey on and parasitize them. P. occidentalis workers bite each other to communicate the time to start working.
P. occidentalis belongs to the subfamily Polistinae. Polistines are one of six subfamilies of the Vespidae, and the subfamily contains four tribes, with Polybia belonging to the Epiponini. P. occidentalis is a black and yellow wasp - a black base with few yellow stripes on its abdomen. Its wings are thin and the thorax is attached to the abdomen by a long, thin petiole. Workers have a mean dry weight ranging from 3.80 to 6.71 mg. Its costal length ranges from 3.6 to 4.7 mm. Queen wasps are differentiated from workers because they have visibly larger ovaries, which are filled with eggs. Males are differentiated from workers and queens due to their visible testes.

Rare
Under 5% of wildlife watchers report a Yellow-Banded Polybia Wasp sighting in San José on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 210th most-seen of the 239 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March, May, October and December
In those months about 10% of wildlife watchers report a Yellow-Banded Polybia Wasp in San José on a given day, against under 5% in January–February, April, June–September and November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-Banded Polybia Wasp sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 14
Of the 14 cities where we can rate Yellow-Banded Polybia Wasp sightings, San José ranks 13th at under 5%. The best odds are in Valencia (Venezuela, about 40%), São Luís (Brazil, about 30%) and Fortaleza (Brazil, about 30%).
GBIF citizen-science records
It is estimated from how often the Yellow-Banded Polybia Wasp is recorded against all the insects logged in San José (5 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.
