Bees
Not all bees are created equal. Of the 22,000 known species of bees, only 7 species are recognized as true honey bees. According to Wikipedia, Honey bees are a subset of bees in the genus Apis, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax.
Of these seven species, A. mellifera and A. cerana indica are the most commonly kept bees for pollination and honey production.
Maintaining a healthy apiary (or bee yard) requires several considerations. Weather, available foraging land, the size of the bees, and the number of hives can all affect the quality of the bees' work, whether in pollination or in honey production. Beekeepers must also be alert to vandalism, competition, and CCD. For more information on modern beekeeping, visit this article on Wikipedia.org (link opens in a new tab).
