How does the age of a worker bee influence its role in the colony?

The role of a worker bee in the colony is closely linked to its age due to the physiological and behavioral changes that occur as the bee matures. As worker bees age, they undergo development that affects their glandular systems, which in turn influences their responsibilities.

Younger worker bees typically start their lives taking care of the brood, which involves tasks such as cleaning the cells, feeding larvae, and tending to the queen. As they grow older, typically around 2-3 weeks, their roles shift to foraging and collecting nectar and pollen, as well as guarding the hive. This transition is a result of changes in the development of glands, such as the hypopharyngeal glands, which become more active and allow them to produce royal jelly and food for the larvae early on.

In contrast, these glandular changes and the corresponding behavioral shifts do not solely rely on the size or strength of the bee, nor do they completely dictate honey production capabilities. A bee’s age is indeed the determining factor that influences the stage of its development and the specific tasks it will take on within the hive.
