Scaptotrigona postica (also known locally in Brazil as mandaguari) is a species of stingless bee that lives mainly in Brazil. It is a eusocial bee in the tribe Meliponini. S. postica is one of 25 species in the genus Scaptotrigona and is a critical pollinator of the tropical rain forests of Brazil. They construct their nests in hollowed sections of tree trunks, allowing for effective guarding at the nest entrance. This species shows colony structure similar to most members of the Meliponini tribe with three roles within the colony: queen, worker, and male. S. postica individuals have different forms of communication, from cuticular hydrocarbons to pheromones and scent trails. Communication is especially useful during worker foraging for nectar and pollen through the Brazilian tropical rainforests. S. postica is a very important pollinator of the Brazilian tropical rainforests and is widely appreciated for its honey. Stingless bees account for approximately 30% of all pollination of the Brazilian Caatinga and Pantanal ecosystems and up to 90% of the pollination for many species of the Brazilian Atlantic Forest and the Amazon.

With luck
About 10% of wildlife watchers report a Brazilian Robust-Stingless Bee sighting in Brasilia on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 102 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May and June
In those months about 20% of wildlife watchers report a Brazilian Robust-Stingless Bee in Brasilia on a given day, against under 5% in January, March–April, July and September–October, the lowest months. Those are among Brasilia's driest months, with about 15 mm of rain a month against 220 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Brazilian Robust-Stingless Bee sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Brazilian Robust-Stingless Bee sightings, Brasilia ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Salvador (Brazil, about 10%).
Same family: Apidae
The closest relatives of the Brazilian Robust-Stingless Bee that you can see in Brasilia (family Apidae, Honey Bees, Bumble Bees, and Allies) are Narrow Stingless Bee (about 20%), Spiny-Legged Stingless Bee (about 20%) and Clavate-Legged Stingless Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Brazilian Robust-Stingless Bee is recorded against all the insects logged in Brasilia (21 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.
