Western honey bee and Africa", making conservation of wild-bee diversity important. They further argue that the difficulty of controlling drones for mating is a serious handicap and a sign that domestication is not complete, in particular as "extensive gene flow usually occurs between wild/feral and managed honeybee populations". The honey bee is a colonial insect which is housed, transported by and sometimes fed by beekeepers. Honey bees do not survive and reproduce individually, but as part of the colony (a superorganism). Honey bees collect flower nectar and convert it to honey, which is stored in the hive. The nectar, transported in the bees'
Western honey bee resources, forming a winter cluster in colder climates, migratory swarming in Africa, and enhanced foraging behavior in desert areas. All together, these variations resulted in 28 recognized subspecies, all of which are cross-fertile. The subspecies are divided into four major branches, based on work by Ruttner and confirmed by mitochondrial DNA analysis. African subspecies belong to branch A, northwestern European subspecies branch M, southwestern European subspecies branch C and Middle-Eastern subspecies branch O. Unlike most other bee species, honey bees have perennial colonies which persist year after year. Because of this high degree of sociality and permanence, honey bee colonies
