Happy Bee Week! Each episode this week gives you the buzz on our powerful, pollinating friends. Bees spend their lives flitting from blossom to blossom, drinking each flower’s sweet nectar. And some have a special way of defending themselves: a sharp, tiny stinger in their butts. But why do bees sting? We asked Johns Hopkins graduate student Abel Corver to help us find the answer.
