Most of the colony, up to 60,000, is made up of the worker bee, all of which are female. A worker bee can’t lay eggs, so the ladies’ role is to fly from tree to tree, collecting nectar and pollen—called grafting. Civilisation’s food supply depends on the worker bees grafting which, as a knock-on effect, pollinates crops.
After the nectar is sucked up the bee will carry it back to the hive to store in wax cells. To release all the pent up frustration of not being a queen, the Creator endowed the girls with a nasty stinger to inflict pain on Jenko, Junior and Romo, but mostly Jenko.
