A worker bee is any female bee in the colony that cannot reproduce at the same capacity as the colony’s queen bee. Worker bees may occur in many bee species, but it is a term most used to describe honey bees. These worker bees gather pollen from flowers, carry it back to the hive in their pollen baskets on their back legs. It is then used to develop the brood. Almost all of civilization’s food supply (maize is a noteworthy exception) depends greatly on crop pollination by honey bees, whether directly eaten or used as forage crops for animals that produce milk and meat.
