The only caste in a termite colony whose members can feed themselves are the workers. Workers are responsible for foraging for food and bringing it back to the colony to feed the other members of the colony, including the reproductives, soldiers, and nymphs. The reproductives, soldiers, and nymphs are unable to feed themselves and rely on the workers for sustenance. The workers have specialized mouthparts that allow them to chew and process food, while the other castes have mouthparts that are not well-suited for feeding.
