Summary:

- Certain species of caterpillars have evolved specialized body hairs that can detect vibrations, allowing them to sense the approach of predators.
- These caterpillar hairs act as tiny "ears," picking up on the low-frequency vibrations made by predators moving through the environment.
- By being able to "hear" approaching threats, the caterpillars can quickly react and take evasive action, such as dropping off the plant or curling up, to avoid being eaten.
