does a bee always die after it stings
Bee sting Bees with barbed stingers can often sting other insects without harming themselves. Queen honeybees and bees of many other species, including bumblebees and many solitary bees, have smoother stingers with smaller barbs, and can sting mammals repeatedly.[3]
Steve Irwin Irwin died at 44, after being pierced in the heart by a stingray barb while filming an underwater documentary film titled Ocean's Deadliest.
Bee sting Although it is widely believed that a worker honey bee can sting only once, this is a partial misconception: although the stinger is in fact barbed so that it lodges in the victim's skin, tearing loose from the bee's abdomen and leading to its death in minutes, this only happens if the skin of the victim is sufficiently thick, such as a mammal's.[3] Honey bees are the only hymenoptera with a strongly barbed sting, though yellow jackets and some other wasps have small barbs.
