Answer Details
The caste of termites that lacks pigmentation is the "worker". Workers are the caste of termites responsible for carrying out most of the work in the colony such as foraging, nest-building, and taking care of the young. They are generally small, pale, and have soft bodies with no wings. Since workers spend most of their time underground, they do not require pigmentation. On the other hand, soldiers have well-developed jaws for defense, and the king and queen have wings for mating and founding new colonies.
