Western honey bee "Apis mellifera" is thought to have originated in Europe, Asia, and Africa. Western honey bee The western honey bee or European honey bee ("Apis mellifera") is the most common of the 7–12 species of honey bee worldwide. The genus name "Apis" is Latin for "bee", and "mellifera" is the Latin for "honey-bearing", referring to the species' production of honey. Like all honey bees, the western honey bee is eusocial, creating colonies with a single fertile female (or "queen"), many normally non-reproductive females or "workers," and small proportion of fertile males or "drones." Individual colonies can house tens of thousands of
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
