The adult worker bee bites it's way out of the cell 21 days after the egg is laid. The drone takes 24 days and the queen 16 days. From the human point of view, honey is the prime product of the honeybee. Honey is a foodstuff, which is produced by the honeybee from the nectar of blossoms, which bees collect, transform, combine with specific substances of their own, and store and leave in honeycombs. Bees use the honey to feed the larvae during the winter.
Flowers have special glands called nectaries that produce nectar.
Nectar is the sweet liquid which plants produce to attract insects for pollination. It consists of sugars dissolved in water. Honeybees suck up nectar from the nectaries of the flower with their long tongues and store it in their honey sacs. When the honeybee has filled it's honey sac with nectar, it returns to the hive. In the hive the bee regurgitates the nectar and passes it to the hive bees who put it in an empty cell in the hive for use as needed.
