Newborn bees mainly eat royal jelly. Royal jelly is a milky serum secreted by the vegetative glands of young worker bees that cultivate larvae in bee nests, which plays a key role in promoting the development of female reproductive organs. In addition, after three days, the larvae will start eating pollen and honey fed by worker bees. Honey is another main food for newborn bees, which is high in sugar and helps to maintain their physical strength. Pollen is also an important food for bees. It is rich in protein, which is the food for big larvae of bees and the protein source for adult worker bees.

In the bee colony, worker bees and drones mainly eat pollen and nectar all their lives. In the absence of external honey sources, they will also eat some supplementary feeds, such as syrup and soybean powder.
