Ropalidia fasciata
In 3 days ~10% in a week ~20%
Ropalidia fasciata, a common paper wasp, is a wide-ranging species that is distributed from India to the Lesser Sunda Islands, Palawan, and Ryukyu Islands, occupying the northern edge of Ropalidia's larger distribution. These primitively eusocial wasps are unique in that they do not exhibit the strict matrifilial, single-queen social structure found in many species of social insects. Instead, colonies are founded based on associations between several females, or 'foundresses'.
Ropalidia fasciata belongs to one of the largest wasp taxa. Roughly 180 other species belong to the genus Ropalidia. In discussion, R. fasciata is often grouped with and compared to Ropalidia marginata. R. fasciata was classified by Johan Christian Fabricius in 1804.
R. fasciata appears with a red-brown body with yellow stripes, and some black and yellow markings. The species are variable in color pattern, displaying the black markings to various degrees. Queen-like and worker-like individuals are not morphologically distinguishable, but instead are differentiated based on behavior.

Rare
Under 5% of wildlife watchers report a Ropalidia fasciata sighting in Taipei on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 602nd most-seen of the 765 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Ropalidia fasciata in Taipei on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 cities where we can rate Ropalidia fasciata sightings, Taipei ranks 4th at under 5%. The best odds are in Naha (Japan, about 20%), Tainan (Taiwan, about 10%) and Kaohsiung (Taiwan, about 10%).
Same family: Vespidae
The closest relatives of the Ropalidia fasciata that you can see in Taipei (family Vespidae, Hornets, Paper Wasps, Potter Wasps, and Allies) are Black-Bellied Hornet (about 10%), Yellow-Legged Hornet (about 10%) and Black-Tailed Hornet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ropalidia fasciata is recorded against all the insects logged in Taipei (7 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.
