Ropalidia marginata
In 3 days ~10% in a week ~20%
Ropalidia marginata is an Old World species of paper wasp. It is primitively eusocial, not showing the same bias in brood care seen in other social insects with greater asymmetry in relatedness. The species employs a variety of colony founding strategies, sometimes with single founders and sometimes in groups of variable number. The queen does not use physical dominance to control workers; there is evidence of pheromones being used to suppress other female workers from overtaking queenship.
R. marginata was originally described by Johan Christian Fabricius in 1793 under the name Vespa ferruginea, but that name was previously applied to a different species, so the oldest available name for the species was given by Amédée Louis Michel le Peletier in 1836. One of its subspecies, R. marginata jocund from New Guinea and Australia, was described in 1898, and two others, R. marginata rufitarsis from Myanmar and R. marginata sundaica from Indonesia and the Malay Peninsula, were described in 1941. R. marginata is an insect, having six legs. It is in the order Hymenoptera, containing wasps, ants and bees. It is in the family Vespidae, with wasps, yellow jackets, and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Ropalidia marginata sighting in Bangkok on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 228th most-seen of the 245 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.
September
In that month about 10% of wildlife watchers report a Ropalidia marginata in Bangkok on a given day, against under 5% in October to August, the lowest months. That is one of Bangkok's wettest months, with about 280 mm of rain against 10 mm in December.
8th of 8
Of the 8 cities where we can rate Ropalidia marginata sightings, Bangkok ranks 8th at under 5%. The best odds are in Nagpur (India, about 20%), Chennai (India, about 20%) and Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 20%).
GBIF citizen-science records
It is estimated from how often the Ropalidia marginata is recorded against all the insects logged in Bangkok (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.
