What is a characteristic behavior of subterranean termites?

Subterranean termites are known for their strong association with the soil, which is crucial for their survival and colony structure. They thrive in damp conditions and often build their nests underground or in wood that is in contact with the soil. This behavior allows them to access moisture and helps them maintain the humidity levels necessary for their survival.

Their reliance on soil is essential for their feeding habits, as they generally consume wood and other cellulose materials that come into contact with the ground. Furthermore, their tunneling behavior through the soil aids in their movement and foraging for food sources. This characteristic distinguishes them from other termite types that may infest solely above-ground materials or do not have the same environmental requirements.

In contrast, the other options present behaviors that do not align with the known habits of subterranean termites. For example, they do not solely infest above-ground materials, nor do they typically create nests in open air like some species of termites that are more arboreal. Additionally, subterranean termites are attracted to dark and humid environments rather than avoiding them, as humidity plays a vital role in their nesting and feeding behaviors.
