The tropical moths produce ultrasound in response to bat sonar, which may serve as a warning or jam bat echolocation.

Hawkmoths produce anti-bat ultrasound
TLDR
Hawkmoths present a novel and tractable system to study both the function and evolution of anti-bat defences, and preliminary data indicate that females also produce ultrasound to touch and playback of echolocation attack, but they do so with an entirely different mechanism.
Tiger Moth Jams Bat Sonar
TLDR
Using ultrasonic recording and high-speed infrared videography of bat-moth interactions, it is shown that the palatable tiger moth Bertholdia trigona defends against attacking big brown bats (Eptesicus fuscus) using ultrasonic clicks that jam bat sonar.
