Melittology is a branch of entomology concerning the scientific study of bees. It can also be called apiology or apicology. Melittology covers the species found in the clade Anthophila within the superfamily Apoidea, comprising more than 20,000 species, including bumblebees and honey bees. Managed bees, like honeybees and some bumblebees, account for a small percentage of all bee species.
