What caste of termites makes up the majority of a termite colony?

In a termite colony, the majority of the population consists of worker termites. The primary roles of workers include foraging for food, caring for the young, maintaining and repairing the nest, and providing overall support for the colony's day-to-day activities. They do not have wings and are typically sterile, which allows them to focus on their essential functions within the colony.

The other castes, while crucial, do not make up the bulk of the population. Swarmers, for example, are the reproductive individuals that leave the colony to mate and establish new colonies. Soldiers, on the other hand, are tasked with the defense of the colony and are fewer in number compared to workers. Winged adults refer specifically to the reproductive swarmers, which only represent a portion of the colony's overall composition. Therefore, the worker caste is fundamentally necessary for the survival and functionality of the colony, making it the most populous group within a termite colony.
