Nannotrigona testaceicornis is a eusocial stingless bee species of the order Hymenoptera and the genus Nannotrigona. Its local common name is abelhas iraí. This species has a large geographic distribution and occupies different biomes, including urban areas, around Neotropical America. The bees of this species nest in trees or artificial cavities because of this broad distribution. N. testaceicornis is important for agriculture because it will pollinate a vast number of plant species year round.
Nannotrigona testaceicornis is a member of the family Apidae of eusocial bees within the order Hymenoptera. The subfamily Meliponini is commonly referred to as "stingless bees." The genus Nannotrigonna has about nine known species and ranges from Sonora, Chihuahua, and San Luis Potosí, Mexico, to Santa Catarina, Brazil, and Paraguay.
Nannotrigona testaceicornis bees are black and generally have grey hairs with a coarse and wrinkled thorax. Along with the rest of the genus Nannotrigonis, they are about 3 to 5 millimeters long. There is much variation within the species genotype, leading to variation in the venation of the wings. Colonies consist of about 2000... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Nannotrigona testaceicornis is recorded against all the insects logged in Rio de Janeiro (31 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.
