A hungry bat screeches out ultrasonic waves and listens as they echo off surrounding objects. One of those echoes sounds an awful lot like a tasty moth, so it swoops in for the kill--but grabs In addition, the moth size–auditory sensitivity relationships at each frequency differed between three geographic areas, with a match to the distribution of echolocation frequencies of sympatric bat species, suggesting that perhaps it is the relationship between size and sensitivity of moth ears, more than the absolute threshold per se, that reflects the impact of bat predation.

For the moth as prey, there is little benefit in evolving a defence that depends on detecting a single bat species where others may be present. However, for bats, there would be advantages in developing a single strategy to avoid detection by the moth community as long as the bat community remained diverse in terms of prey selection and call structure.
