Honey Bees are a social insect and populate in colonies. These colonies have a three-tier caste system which consists of: the queen bee that is responsible for producing eggs; male drones that mate with the queen; and female worker bees that don't reproduce. Their wax hives are perennial and can harbor up to 80,000 bees simultaneously. They stay most active in summer months; during winter, bees gather within the hive and self-regulate the internal temperature to keep warm. Honey Bees are greatly depended upon in agriculture for pollination and they account for 80% of all insect pollination.
