Honeybees

Honey bees (or honeybees) are a subset of bees, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax. Honey bees are the only extant members of the tribe Apini, all in the genus Apis. Currently, there are only seven recognized species of honey bee with a total of 44 subspecies (Engel, 1999) though historically, anywhere from six to eleven species have been recognized. Honey bees represent only a small fraction of the approximately 20,000 known species of bees. Some other types of related bees produce and store honey, but only members of the genus Apis are true honey bees.

Origin, systematics and distribution:Honey bees as a group appear to have their center of origin in South and Southeast Asia (including the Philippines), as all but one of the extant species are native to that region, notably the most plesiomorphic living species (Apis florea and A. andreniformis). The first Apis bees appear in the fossil record at the Eocene-Oligocene boundary, in European deposits dating about 35 million years ago. The origin of these prehistoric honey bees does not necessarily indicate that Europe is where the genus originated, only that it occurred there at that time. There are few known fossil deposits in the suspected region of honeybee origin, and fewer still have been thoroughly studied.

The close relatives of modern honey bees - e.g. bumblebees and stingless bees - are also social to some degree, and social behavior seems a plesiomorphic trait that predates the origin of the genus. Among the extant members of Apis, the more basal species make single, exposed combs, while the more recently-evolved species nest in cavities and have multiple combs, which has greatly facilitated their domestication.

Most species have historically been cultured or at least exploited for honey and beeswax by humans indigenous to their native ranges. Only two of these species have been truly domesticated, one (Apis mellifera) at least since the time of the building of the Egyptian pyramids, and only that species has been moved extensively beyond its native range.
