Bees are flying insects closely related to wasps and ants. Bees are a monophyletic lineage within the superfamily Apoidea, presently classified by the unranked taxon name Anthophila. There are nearly 20,000 known species of bee, in nine recognized families,[1] though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants.
A wasp is a predatory flying stinging insect of the order Hymenoptera and suborder Apocrita that is neither a bee nor an ant. A narrower and simpler but popular definition of the term wasp is any member of the aculeate family Vespidae. Wasps are critically important in natural biocontrol as almost every pest insect species has at least one wasp species that is a predator upon it. Parasitic wasps are increasingly used in agricultural pest control as they have little impact on crops
