The Africanized honey bee has descended from tropical African bees (Apis mellifera scutellata) that were introduced to South America in 1956. These African bees mated with the European honey bee to create the hybridized or 'Africanized' honey bee. These bees have migrated since their introduction, reaching the lower United States in 1990.
