Which caste of termites makes up the majority of a colony's population?

The majority of a termite colony is made up of workers. These workers are responsible for several critical tasks that are essential to the colony's survival and success. They gather food, care for the queen and the larvae, maintain and repair the nest, and defend against threats. The role of the worker caste is vital because they perform the day-to-day functions that keep the colony thriving.

Unlike soldiers, who primarily focus on defense, and reproductives, which include the queen and kings focused on reproduction, workers are the backbone of the colony. Their numbers and activities are what largely support the colony's structure and growth. Scouts are a smaller subset that specifically seeks out food sources and potential nesting sites, adding to the complexity of the colony’s operation but not dominating its population.

The worker caste's large numbers and diverse responsibilities underscore their importance in maintaining the health and expansion of termite colonies.
