Worker policing occurs via egg-eating in "Apis mellifera" colonies. Ustica is home of the honeybee "Apis mellifera sicula". Different sub-species of "Apis mellifera" exhibit differing swarming characteristics. Now beekeeping with "Apis mellifera" predominates in India. It also occurs in the Cape honey bee "Apis mellifera capensis". The Rif mountains are also home to the honey bee subspecies "Apis mellifera major". "A. cerana" is much more resistant than Apis mellifera to cold and predators. The native habitat of "Apis mellifera scutellata" includes the southern and eastern regions of Africa. It also attracts introduced honey bees (Apis mellifera). In the rest of France it has been substituted by "Apis mellifera ligustica". This discrimination is even more precise than "Apis mellifera", or the western honey bee. "Nosema apis" is a single-celled parasite of the western honey bee ("Apis mellifera"). Apart from "Apis mellifera", there are six other species in the genus "Apis". The cape bee "Apis mellifera" subsp. "capensis" can reproduce asexually through a process called thelytoky. The most important prey item in their diet is Hymenoptera, mostly "Apis mellifera".
