Grote’s Bertholdia: when bats are detected nearby, these moths emit a rapid series of ultrasonic clicks that act as a “jammer,” interfering with the bat’s sonar signals so that the moth can avoid detection
The Grote’s bertholdia moth (B. trigona) is capable of emitting about 4,500 ultrasonic “clicks” per second. While there are other types of moths that use ultrasonic signals (in various ways) to avoid being preyed upon by bats, none of them have a more rapid-fire pace than this species.
The barrage of signals provides the moth with a way to remain hidden, because it interferes with the echolocation that bats use to navigate and locate prey.
As this article from Smithsonian explains:
… when approached by the bats, the moths produced their own ultrasonic clicking sounds at a rate of 4,500 times per second, blanketing the surrounding environment and cloaking themselves from sonar detection.
This article also expands upon the use of ultrasonic signals among moths:
Like other nocturnal insects, moths need to contend with bats. Unlike grasshoppers or beetles, they have soft bodies without spines or hard cuticles to protect them. Yet bats’ reliance on echolocation has given moths a way to avoid ending up as food: by tapping into their predators’ acoustic signals. Many have evolved ears that can hear the calls of bats. Some moths make ultrasonic squeaks, chirps, or clicks to warn their predators (honestly or not) that they are poisonous. Others generate near-constant, ultrasonic buzzes capable of jamming bat sonar.
