1. Foraging: Worker bees, which are responsible for gathering nectar, fly from flower to flower collecting nectar using their long, tube-like tongues called proboscis. They also collect pollen, which serves as a protein source for the hive.
2. Collecting Nectar: When a bee finds a flower with nectar, it uses its proboscis to suck up the liquid. Nectar is a sugary fluid produced by flowers to attract pollinators like bees. The bee stores the nectar in its honey stomach, a separate pouch from its regular stomach.
3. Transporting Nectar: Once the honeybee has filled its honey stomach with nectar, it returns to the hive. During the return journey, enzymes in the bee’s honey stomach begin to break down the complex sugars in the nectar into simpler sugars.
4. Regurgitation and Evaporation: Back at the hive, the forager bee passes the nectar to a house bee through a process called trophallaxis, which involves regurgitation from mouth to mouth. The house bee then ingests the nectar and continues to process it. Bees have specialized glands that produce enzymes, which further break down the sugars in the nectar. The house bees then spread the nectar across the honeycomb cells.
5. Drying and Sealing: Once the nectar is deposited into the honeycomb cells, bees fan their wings over the cells to speed up the process of evaporation, reducing the water content of the nectar. When the water content reaches around 17-20%, the bees seal the cell with beeswax to preserve the honey.
6. Storage: The sealed honeycomb cells serve as storage for the honey until it is needed by the colony. Honey can be stored for long periods without spoiling due to its low water content and acidic pH, which inhibit the growth of microorganisms.
7. Harvesting: Beekeepers harvest honey by carefully removing frames from the hive containing capped honeycomb cells. They then extract the honey by spinning the frames in a centrifuge, causing the honey to flow out of the cells.

This process of regurgitating nectar from mouth to mouth during trophallaxis is essential for the transformation of nectar into honey within the hive.

Read between the lines and they are basically passing sick from their second stomachs from mouth to mouth! eww but wow!
