Honey bees have barbed stingers that usually remain in the sting.
Honey bees can only sting once. Wasps do not have barbed stingers and can sting repeatedly. In general, wasps are more aggressive than honey bees. Africanized honey bees resemble our familiar European honey bees but are much more aggressive. Africanized bees are dangerous because their victims may be stung by thousands of bees sent out in defense of the hive.
