Much of the work on the role of audition in tympanate moths indicates that they possess ears which are tuned to the predominant frequencies in the echolocation signals of sympatric, insectivorous bats (Roeder, 1970). Since moths are more sensitive to certain frequencies there may be selection for bats whose echolocation signals tend to minimize acoustic reception by the tympanate moths they are hunting.
