Like other insects a bee starts it's life as an egg. The queen bee lays an egg the size of half a grain of rice into a comb cell. After a few days it hatches into a larvae.
The larvae now looks like a grain of rice with a mouth. Worker bees will visit up to 1,300 times a day to fed the larvae bee bread, a mix of nectar, bee pollen and a small amount of royal jelly. If the larvae is to be a queen it is fed solely on royal jelly. Within about 5-6 days the cell will be capped by a worker bee and the larvae will spin into a silk cocoon to then pupate.
The pupae doesn't eat or move but takes the shape of a bee. About ten days later the adult bee emerges .
