Beetles produce an ultrasound 'illusion' to appear toxic, avoiding bats' echolocation.
Flying beetles create an ultrasound 'illusion' to avoid hungry bats, a study finds. Bats use echolocation to hunt nocturnally, emitting pulses to detect prey. Insects, including beetles, have evolved strategies to evade their predators, such as producing their own ultrasound in response to a bat's call. This ultrasound 'illusion' tricks bats into thinking the beetles are toxic, allowing them to escape unharmed.
