Eastern honey bee (Apis cerana), or the Asiatic honey bee, is a species of honey bee found in southern and southeastern Asia, including China, Pakistan, India, Korea, Japan, Malaysia, Nepal, Bangladesh, Papua New Guinea, Solomon Islands and Australia. This species is the sister species of Apis koschevnikovi, and both are in the same subgenus as the western (European) honey bee, Apis mellifera. Eastern honey bee is known to live sympatrically as well with Apis koschevnikovi within the same geographic location. Eastern honey bee colonies are known for building nests consisting of multiple combs in cavities containing a small entrance, presumably for defense against invasion by individuals of another nest. The diet of this honey bee species consists mostly of pollen and nectar, or honey. Moreover, eastern honey bee is known for its highly social behavior, reflective of its classification as a type of honey bee.
