Which stage in a bee's lifecycle primarily determines whether it will become a worker or a queen?

The larval stage is crucial in determining whether a bee will develop into a worker or a queen. During this stage, the larvae are fed different diets which heavily influence their development. Worker bees are typically fed a diet of pollen and nectar, whereas future queen bees are exclusively fed royal jelly, a nutrient-rich substance produced by worker bees. This specialized feeding triggers the necessary physiological changes that lead to the development of reproductive organs, allowing the queen to fulfill her role in the colony. Hence, the larval stage is key in determining the caste system within the hive, leading to the distinct roles of workers and queens. Understanding the significance of this stage is essential for comprehending bee biology and the dynamics of their social structure.
