Honey bee

Honey bees (or honeybees) are a subset of bees which represent a far smaller fraction of bee diversity than most people suspect; of the approximately 20,000 known species of bees, there are only seven presently-recognized species with a total of 44 subspecies (Engel, 1999; historically, anywhere from six to eleven species have been recognized). These bees are the only living members of the tribe Apini, all in the genus Apis, and all of which produce and store liquefied sugar ("honey") to some degree, and construct colonial nests out of wax secreted by the workers in the colony. Other types of related bees produce and store honey, but only members of the genus Apis are considered true honey bees.

Honey is the complex substance made when the nectar and sweet deposits from plants and trees are gathered, modified and stored in the honeycomb by honey bees. All living species of Apis have had their honey gathered by indigenous peoples for consumption, though for commercial purposes only A. mellifera and A. cerana have been exploited to any degree. Honey is sometimes also gathered by humans from the nests of various stingless bees.
