Royal jelly is a honey bee secretion that is use in the nutrition of the larvae. It is secreted from the hypopharyngeal glands in the heads of young workers and used (among other substances) to feed all of the larvae in the colony, including those destined to become workers. If a queen is needed, a larva is chosen and will receive only royal jelly — and in large quantities — as its food source for the first four days of its growth, and this rapid, early feeding triggers the development of queen morphology, including the fully developed ovaries needed to lay eggs. Some commercial royal jelly suppliers disseminate misinformation such as "Only queen larvae and adult queens are fed royal jelly". All larvae in a colony are fed royal jelly, and adult bees do not consume it at all.
