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.
