What is a characteristic of worker subterranean termites?

Worker subterranean termites are essential to the survival and functioning of their colonies, with one of their primary roles being foraging for food. They are responsible for searching for cellulose-based materials such as wood, which they consume and also bring back to the colony. This foraging is crucial for the nourishment of the entire colony, including the queen, soldiers, and nymphs.

Additionally, workers play a significant role in the maintenance of the nest and the care of the young, highlighting their importance beyond just food gathering. In contrast, the options regarding wings, size as the largest caste, or interaction with the queen do not align with the characteristics of worker termites, who are wingless, smaller than the reproductive caste, and actively engage in caring for and interacting with the queen as part of their communal living structure.
