What is a nurse bees job?

Answer 1

Bees go through different jobs in the first three weeks of their lives, though not all bees do all jobs.
Nurse bees are usually about a week old (after their hyperpharyngeal glands have developed) and they feed larvae. For the first three days all larvae are fed on the secretion from the hyperpharyngeal gland. This is called bee milk or royal jelly. Once a larva is three days old the nurse bees will feed it on a mixture of pollen, nectar and royal jelly until the larval cell is capped. The only exception to this is for a queen larva which is fed only on royal jelly right up until the cell is capped.
A group of nurse bees also feed the queen as she goes about the hive.
