Polistes fuscatus, whose common name is the dark or northern paper wasp, is widely found in eastern North America, from southern Canada through the southern United States. It often nests around human development.

P. fuscatus is a social wasp that is part of a complex society based around a single dominant foundress along with other cofoundresses and a dominance hierarchy.
P. fuscatus is a part of the order Hymenoptera, the suborder Apocrita, the family of Vespidae, and the subfamily Polistinae, the second-largest subfamily within the Vespidae, of which all are social wasps. The Polistinae comprise four tribes, including Polistini, Epiponini, Mischocyttarini, and Ropalidiini. It is characterized by two major behaviors: colony founding and reproductive dominance. P. fuscatus is part of the Polistini tribe and in the genus Polistes. Polistes is one of the five independent-founding groups. Older taxonomic concepts considered P. fuscatus to have a much broader definition, treating several species, including... Wikipedia →

With luck
About 10% of wildlife watchers report a Northern Paper Wasp sighting in Philadelphia on a given day, based on 54 verified sightings from GBIF citizen-science data. It is the 119th most-seen of the 632 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March to November
In those months about 10% of wildlife watchers report a Northern Paper Wasp in Philadelphia on a given day, against under 5% in December to February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Northern Paper 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.
9th of 16

GBIF citizen-science records
It is estimated from how often the Northern Paper Wasp is recorded against all the insects logged in Philadelphia (54 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.
