Why don't bees fly after losing their stinger?

That the stinger cannot be removed without rupturing the apian lower abdomen is the reason why bees die if they sting people. The insect stinger, structured similar to barbed wire that moves around and around like a screw instead of up and down like a syringe, removes digestive material, glands, muscles, and venom sacs and leaves behind fatally big holes at the end of the abdomen. Bees suffer painful deaths for their barbed stingers, which wasps and yellow jackets lack and which explains why they survive stinging other life forms such as people.
