A Natural adaption that hides moths from bats' sonar

avatar

Moths can hide from bat sonar thanks to their naturally adapted wings that absorb the sound waves.

Moths have an array of scales attached to their wings that are barely a millimeter long and a few hundred micrometers thick. Each of them resonates at a particular frequency which results in a wider range of sound absorption when they work together.

The Chinese tusar moth (Antheraea pernyi) and Dactyloceras lucina, a large African moth are two species found with this acoustic stealth capability.
