Caterpillars Sense Electric Fields
British scientists discovered that caterpillars have a sixth sense called electroreception, allowing them to detect electric fields through setae. The study, published in PNAS, examined four caterpillar types. Electroreception helps animals avoid predators, with caterpillars uniquely using it for defense. Researchers simulated predator approaches, noting caterpillars’ stress responses to specific frequencies. This research enhances understanding of caterpillar senses, insect behavior, and the impact of sensory pollution.
