Apis mellifera, the European honey bee, has many subspecies.
The hybrid populations of A. m. mellifera x A. m. ligustica, found in North America and Western Europe, have the reputation of stinging people (and other creatures) for no good reason. The near-extinct "pure" A. m. mellifera is not considered randomly aggressive.
Several researchers and beekeepers describe a general trait of the African subspecies which is absconding, where the Africanized honeybee colonies abscond the hive in times when food-stores are low, unlike the European colonies which tend to die in the hive.
