There are about 20,000 known species of bees. Some bees are able to sting a victim more than once, while others can only sting once and usually die after doing so. It just depends on the species.
Bees store their venom in sacs attached to their stinger and only female bees are able to sting. The stinger is part of the female bee’s reproductive design. Certain species of bees die after stinging because these stingers are attached to their abdomen and have hooks on them. When the bee tries to fly away after stinging something, part of its abdomen is ripped away resulting in its demise.
Honeybees and killer bees are only able to sting their victims once, while bumble bees can sting more than once because their stingers are smooth and do not get caught in the victim’s skin when they go to fly away. Carpenter bees are also able to sting over and over again due to their stingers not being hooked or barbed.
