Bees are any of 20,000 species of insects belonging to the superfamily Apoidea and the order Hymenoptera, including such important pollinators of plants as the bumblebees; the yellow-faced, or plasterer, bees; the mining, or burrower, bees; and the economically important honeybees of the genus Apis, the only domesticated insects besides the silkworm. Honeybees are known for the honey and wax they produce and their ability to communicate with one another through dancelike postures (the so-called dance language).
