Darwin’s Hawkmoth (Xanthopan praedicta) responds to bat ultrasound at sonar-jamming rates: Acoustic data set

This paper reveals that Xanthopan praedicta (Lepidoptera: Sphingidae) is part of the bat-moth coevolutionary dynamic. I played recordings of bat echolocation to live X. praedicta and found that males respond with such dense ultrasound they can likely jam bat sonar. Female X. praedicta and two other sphingid species do not produce ultrasonic responses.

本研究揭示，Xanthopan praedicta（鳞翅目（Lepidoptera）：天蛾科（Sphingidae））是蝙蝠与蛾类协同演化动态的组成部分。笔者向活体X. praedicta个体播放蝙蝠回声定位录音，发现雄性个体可产生高密度超声波，大概率能够干扰蝙蝠的声呐系统；雌性X. praedicta以及另外两种天蛾物种则不会产生超声波应答。
