Ropalidia marginata
In 3 days ~30% in a week ~50%
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 →

With luck
About 10% of wildlife watchers report a Ropalidia marginata sighting in Bengaluru on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 98th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March and April
In those months about 20% of wildlife watchers report a Ropalidia marginata in Bengaluru on a given day, against about 10% in May to February, the lowest months. Those are among Bengaluru's driest months, with about 35 mm of rain a month against 150 mm in September.
4th of 8
Of the 8 cities where we can rate Ropalidia marginata sightings, Bengaluru ranks 4th at about 10%. The best odds are in Nagpur (India, about 20%), Chennai (India, about 20%) and Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 20%).
Same genus: Ropalidia
The closest relatives of the Ropalidia marginata that you can see in Bengaluru (genus Ropalidia, Small Brown Paper Wasps) are Ropalidia cyathiformis (about 10%) and Ropalidia rufoplagiata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ropalidia marginata is recorded against all the insects logged in Bengaluru (56 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.
