Overview

• A new study reveals that ermine moths, despite lacking hearing organs, use a unique wing structure to produce ultrasonic signals that jam the echolocation of bats.
• This discovery showcases a natural example of 'snap through,' a phenomenon engineers typically avoid due to its potential to cause structural instability.
• The moths' aeroelastic tymbals, which generate the ultrasonic signals, could inspire innovations in engineering, particularly in acoustic structural monitoring and soft robotics.
• Researchers utilized advanced techniques like 3D X-ray and confocal microscopy to understand the mechanics behind the moths' sound production.
• The study represents a significant advancement in understanding the acoustic defenses of insects against predators and could lead to new technological developments.
