Drones, male bees, are not physically capable of doing work around the hive. They can't sting, can't collect pollen or nectar, can't take care of the larvae, etc. They pretty much do only two things: eat and mate.

Do drone honey bees have stingers?

The males, or drones, are larger than the workers and are present only in early summer. The workers and queens have stingers, whereas the drones are stingless.

Why do drone bees not have stingers?

A drone is a male honey bee. Unlike the female worker bee, drones do not have stingers. They gather neither nectar nor pollen and are unable to feed without assistance from worker bees. A drone's only role is to mate with an unfertilized queen.
