As an aside, insects often use their feet to “hear” vibrations from the plant they are standing on, allowing them to seemingly “silently” communicate with others on that plant by transmitting vibrations through it, or detect when an animal is coming along.

Notably in my experience, corn rootworm beetle were especially adept at hearing me walking along through corn and hiding before there was any possibility of seeing me. I’d have to stop and be still for a minute for them to start crawling about again.
