I can offer another "why?" How many animals attack a wasp's nest? Almost zero, except other wasps in a territory war? How many animals attack a beehive? Humans, bears, apes,.. pretty any big enough mammal that can climb. So bees not only suffer from much more predators due to their precious honey, in my view they also need to differentiate between "honey maker" and warrior (sting) functions as their poison could contaminate the honey. Why do the males have to die? Because almost none of their enemies can extract a bee sting from their skin. Once stung, the poison glands and some muscles remain with the sting, acting as a "poison pump". This could deter the attacker longer from a second attack. Which makes sense, as the beehive cannot run away from the attacker.
