After receiving a regurgitated stomach-full of nectar from another bee, a middle-aged worker deposits it into a honey cell.
Foraging bees store nectar, the colony's principal source of carbohydrates,
in the so-called honey stomach in their abdomens. When they return to the hive,
they regurgitate the nectar to middle-aged workers, which either distribute
the nectar for immediate consumption or process it into honey and store it
in special honey cells. Sometimes foragers bring water rather than nectar.
Nurse bees—those tending the brood of unborn workers—will use the
water either to dilute honey to feed the brood or, on hot days, to cool
the hive through evaporation (see temperature).

Returning foragers also bring pollen, which they carry in special
pollen "baskets" on their hind legs. Pollen provides colony members
with vital amino acids, vitamins, and fats. It is stored in pollen
cells near the brood cells, so it is readily available to nurse bees,
which fashion the pollen into a kind of bread for supplying nourishment
to developing larvae.
