There are many other bee species that can sting Humans and survive, but the European honeybee has a barbed stinger, so it cannot remove the stinger once it’s stung. In attempting to remove the stinger the bee will rupture its lower abdomen and then die.
Why? What is the evolutionary advantage to that?
My bs answer… they want the thing they sting to know if was them.
“Witness me!!”
