| Abstract: | The tympanic organs of moths we studied in Zimbabwe responded differentially to the echolocation/hunting signals of sympatric, insectivorous bats. Bats employing very high frequencies (> 110 kHz) and/or low intensity cries tend to be first detected by tympanal preparations at distances considerably less than those with more intense, mid-frequency (20-60 kHz) cries. There appears to be some positive correlation between acoustically inconspicous bats and the amount of auditive prey they feed on although there are theoretical disadvantages in producing highly undetectable orientation cries. |
