These are all female and their roles are to forage for food (pollen and nectar from flowers), build and protect the hive, clean and circulate air by beating their wings. Workers are the only bees most people ever see flying around outside the hive.
The bee is the only insect that makes food that humans can eat; honey. Worker Foragers collect nectar from about 2 million flowers just to make around ½ a kilo of honey. The average worker produces one-twelfth of a teaspoon of honey in her lifetime.
Honey bee workers exhibit changes in their duties as they grow older. Newly emerged workers are responsible for cleaning the honeycomb cells to prepare them for eggs or food storage. In a few days, they take on duties like taking out waste, processing nectar, feeding the queen and larvae. They also work to maintain air circulation and keep temperatures stable.
Their wax gland becomes active in their second week, and now they start to help with building and repairs of the comb. Workers’ wax glands become active, and they help build and repair the comb while continuing to tend the queen and feed other workers.
From their 12th to 25th day, workers take on guard roles and defend the hive from infiltration and attack. After three weeks, their wax and food glands shrink, and they begin to fly out on foraging duty.
