Tiger Beetles Use Ultrasonic Mimicry to Evade Bats
New research reveals that nocturnal tiger beetles imitate toxic moths' ultrasonic signals to avoid predation by bats.
- Scientists found that seven species of nocturnal tiger beetles produce ultrasonic clicks when they detect bat echolocation.
- These beetles mimic the ultrasonic warnings of noxious tiger moths, deterring bats from attacking.
- Previous assumptions that the beetles' defensive chemicals deterred bats were disproven through feeding experiments.
- The study suggests that ultrasonic mimicry might be widespread among nocturnal insects.
- Human-induced noise and light pollution could disrupt these delicate ecological interactions.
