0 a substance produced by bees in order to feed young bees and queen bees (= in groups of bees, the single large females that produce eggs):
When a queen bee begins to produce fewer eggs, workers create a new queen by feeding extra dosages of royal jelly to select cells in the hive.
A queen's early exposure to royal jelly allowed her to mature into a queen rather than a worker bee.
Bee pollen and royal jelly can provoke dangerous allergic reactions.
