Scientists Put Caterpillars in an Ultraquiet Chamber to Learn How They Hear Without Ears

In a peaceful garden, a tobacco hornworm caterpillar senses danger from an approaching wasp, despite not having visible ears. Scientists are investigating how these caterpillars detect predators, suspecting that tiny, sensitive hairs on their bodies allow them to hear. This research, conducted in a soundproof anechoic chamber, involves observing caterpillars’ reactions to vibrations and airborne sounds. By using an accelerometer, researchers measure the vibrations affecting the caterpillars, discovering that they respond to certain sound thresholds. Understanding these mechanisms could not only solve a natural mystery but also inspire new microphone technologies. QUESTION: How might understanding the sensory abilities of caterpillars influence future technological advancements?
