Melipona is a genus of stingless bees, widespread in warm areas of the Neotropics, from Sinaloa and Tamaulipas (México) to Tucumán and Misiones (Argentina). At least 40 species are known. The largest producer of honey from Melipona bees in Mexico is in the state of Yucatán where bees are studied at an interactive park called "Bee Planet" which is within the Cuxtal Ecological Reserve.
Several species are kept for honey production, such as in Brazil, where some are well-known enough to have common names. Melipona honey has long been used by humans and now is of minor commercial importance. Research is going on in improved beekeeping techniques.
Usage examples of "melipona".
In the series between the extreme perfection of the cells of the hive-bee and the simplicity of those of the humble-bee, we have the cells of the Mexican Melipona domestica, carefully described and figured by Pierre Huber.
The Melipona itself is intermediate in structure between the hive and humble bee, but more nearly related to the latter: it forms a nearly regular waxen comb of cylindrical cells, in which the young are hatched, and, in addition, some large cells of wax for holding honey.
Reflecting on this case, it occurred to me that if the Melipona had made its spheres at some given distance from each other, and had made them of equal sizes and had arranged them symmetrically in a double layer, the resulting structure would probably have been as perfect as the comb of the hive-bee.
Hence we may safely conclude that if we could slightly modify the instincts already possessed by the Melipona, and in themselves not very wonderful, this bee would make a structure as wonderfully perfect as that of the hive-bee.
