- Caterpillars have a sixth sense that most land-based animals do not.
- They can sense electric fields around them with small bristles called setae on its body — a feat called electroreception.
- Caterpillars, which are also arthropods, may break this mould, by using the electroreception to sense predatory insects nearby.
- The caterpillars’ setae responded to frequencies of 50-350 Hz, possibly to help distinguish between threats and non-threats.
