Tetragonisca angustula is a small eusocial stingless bee found in México, Central and South America. It is known by a variety of names in different regions (e.g., jataí, yatei, jaty, virginitas, angelitas inglesas, españolita, mariola, ramichi, chipisas, virgencitas, and mariolitas). A subspecies, Tetragonisca angustula fiebrigi, occupies different areas in South America and has a slightly different coloration.
Tetragonisca angustula is a very small bee and builds unobtrusive nests, allowing it to thrive in urban areas. It also produces large amounts of honey, and is thus frequently kept in wooden hives by beekeepers. T. angustula hives are often overlooked, and since the bee lacks a stinger, it is not seen as a threat to humans.
Many of their behaviors are concerned with colonizing a new nest and producing offspring, demonstrated by their swarming and nursing behaviors; however, a special caste of T. angustula are soldiers who are slightly larger than the workers. The soldiers in a T. angustula nest are very good at protecting the hive against intruders, making up for the lack of a stinger in their species. The accuracy of their recognition between nestmate and non-nestmate is some of the highest among bees. Some of these soldiers hover in mid air outside the nest, which is seen in the adjacent picture.

With luck
About 10% of wildlife watchers report a Narrow Stingless Bee sighting in Cali on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 52 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Narrow Stingless Bee in Cali on a given day, against under 5% in March–April, August, October and December–January, the lowest months. That is one of Cali's driest months, with about 40 mm of rain against 150 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Narrow Stingless Bee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
16th of 20
Of the 20 cities where we can rate Narrow Stingless Bee sightings, Cali ranks 16th at about 10%. The best odds are in Salvador (Brazil, about 30%), Guatemala City (Guatemala, about 30%) and Recife (Brazil, about 20%).
Same family: Apidae
The closest relatives of the Narrow Stingless Bee that you can see in Cali (family Apidae, Honey Bees, Bumble Bees, and Allies) are Belted Orchid Bee (about 10%) and Black Orchid Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Narrow Stingless Bee is recorded against all the insects logged in Cali (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.
