A beehive is, in a general sense, an enclose structure in which some species of honey bees (genus Apis) live and raise their young. Natural beehives (typically referred to simply as "nests") are naturally-occurring structures occupied by honey bee colonies, while domesticated honey bees are kept in man-made beehives in a location known as an apiary; it is these man-made structures that are most typically referred to as "beehives". Only species of the subgenus Apis live in hives, and, of these, only the Western honey bee (Apis mellifera) and the Eastern honey bee (Apis cerana) are kept in domestication.
