一场进化战争正在蝙蝠和飞蛾之间展开，蝙蝠使用超声波来定位昆虫猎物，飞蛾使用微型耳朵来倾听接近的蝙蝠。虽然蝙蝠回声定位的最高频率是212 kHz，但蛾的听力上限被认为要低得多。在这里，我们表明，更大的蜡蛾，大蜡蛾，能够听到接近300 kHz的超声波频率;任何动物的最高频率敏感度。在动物王国中，大蜡蛾对听觉频率的敏感性是前所未有的，它已经准备好迎接蝙蝠在蝙蝠蛾进化战争中做出的任何回声定位呼叫适应。
An evolutionary war is being played out between the bat, which uses ultrasonic calls to locate insect prey, and the moth, which uses microscale ears to listen for the approaching bat. While the highest known frequency of bat echolocation calls is 212 kHz, the upper limit of moth hearing is considered much lower. Here, we show that the greater wax moth,Galleria mellonella, is capable of hearing ultrasonic frequencies approaching 300 kHz; the highest frequency sensitivity of any animal. With auditory frequency sensitivity that is unprecedented in the animal kingdom, the greater wax moth is ready and armed for any echolocation call adaptations made by the bat in the on-going bat–moth evolutionary war.
