How do subterranean termites primarily protect themselves from natural enemies?

Subterranean termites primarily protect themselves from natural enemies through the construction of shelter tubes. These tubes serve as protective tunnels made from soil, wood particles, and their own saliva, allowing the termites to travel between their nest and food sources while remaining shielded from predators and environmental threats. The shelter tubes provide a microenvironment that maintains humidity levels essential for their survival, and they also camouflage the termites from potential threats.

Utilizing these tubes enables subterranean termites to access wood and other cellulose-based materials without exposing themselves to open air, where they could be vulnerable to birds, ants, or other predatory organisms. This behavioral adaptation is crucial for their survival and successful foraging activities.
