Ropalidia plebeiana is a eusocial temperate paper wasp. It is unique, as it is the only temperate wasp in the typically tropical Ropalidia genus. R. plebeiana is widely distributed in eastern Australia, and recently have been found making huge nest aggregations, with thousands of nests on trunks of trees, in south-eastern New South Wales.
R. plebeiana is in the Vespidae family along with thousands of other wasp species. The genus, Ropalidia, is typically made up of wasps that live in tropical locations, but R. plebeiana is the exception. The genus, Ropalidia is classified as brown paper wasps. Although R. plebeiana does not yet have a place within the taxonomy of the Ropalidia family, it has been discovered to be closely related to R. proletaria.
R. plebeiana is a white-faced, brown paper wasp. It is a medium-size paper wasp, with a reddish-brown-colored body. There are small, thin white rings on its shoulders, waist, and abdomen. Nests of R. plebeiana are seen as a horizontal single comb with an irregular shape, and they are grayish brown in color. Nests have been found to have 1–3 males and anywhere from 13 to 28 females...

GBIF citizen-science records
It is estimated from how often the White-Faced Brown Paper Wasp is recorded against all the insects logged in Blue Mountains National 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.
