Common names
The species is commonly referred to as the Mexican stingless bee.
Description
Scaptotrigona mexicana is a small to medium‑sized eusocial bee belonging to the stingless bees (Meliponini). Workers are typically dark brown to black with a robust body shape and reduced or absent stingers, a characteristic of the tribe. Morphological details such as wing venation and mandibular structure conform to the diagnostic traits of the genus Scaptotrigona.
Distribution and habitat
The species is native to Mexico and adjacent regions of Central America. It inhabits tropical and subtropical forests, where it nests in cavities of living or dead trees, as well as in underground or man‑made structures in some cases. Precise range limits are not fully documented; however, records confirm its presence in several Mexican states.
Biology and ecology
-
Social structure: Like other meliponine bees, S. mexicana forms colonies with a single reproductive queen, a contingent of sterile female workers, and a seasonal production of males (drones). Colony size can range from a few hundred to several thousand individuals, depending on environmental conditions.
-
Nest architecture: Nests consist of a brood chamber surrounded by storage pots (cerumen pots) for honey and pollen. The entrance is typically guarded by a worker “gatekeeper.”
-
Foraging behavior: Workers collect nectar, pollen, and resin from a diversity of flowering plants, contributing to pollination of both wild flora and cultivated crops. They exhibit site fidelity and may communicate resource locations through pheromonal cues and tactile signals.
-
Honey production: S. mexicana produces a small quantity of honey stored in cerumen pots. The honey is of cultural and economic importance in some local communities, who harvest it for consumption and traditional medicine.
-
Reproduction: Swarming occurs when a new queen is reared and a portion of the workforce departs to establish a new nest. Mating flights typically take place in the early morning; queens mate with multiple drones, a behavior common to many meliponine species.
Interaction with humans
-
Meliponiculture: The species is occasionally kept in managed hives for honey production and pollination services. Its small colony size and gentle temperament make it suitable for small‑scale apiculture.
-
Conservation status: No formal assessment (e.g., IUCN Red List) has been published for S. mexicana. Habitat loss due to deforestation and agricultural expansion is considered a potential threat, though precise population trends are not documented.
Research
Scientific interest in Scaptotrigona mexicana focuses on its taxonomy, phylogenetic relationships within Meliponini, and its role in pollination networks. Molecular studies have used mitochondrial DNA sequences to clarify its placement within the genus.
