More info: All male bees are drones but a female bee may be a worker or a queen. A colony often contains one queen and tens of thousands of workers.
Worker bees make up at least 85% of the colony and do all the hard work, including collecting nectar and pollen.
Although they are female, worker bees are infertile due to a pheromone released by the queen that suppresses the worker bee ability to develop the appropriate reproductive apparatus. Worker bees have the biological capabilities to lay eggs, but not to fertilize them. This means that when they do lay eggs, those eggs are destined to become drones.
