Abstract

We examined the responses of moths to an auditory stimulus in the field with respect to moth size, moth activity state (at rest or flying), whether it responded, and response type. Moths most commonly responded by changing flight direction. Flying moths responded significantly more often to the auditory stimulus than did resting moths; small- and medium-sized moths responded significantly more often than larger ones. We found no differences in use of response types between size classes. We suggest that these behavioral responses to the auditory stimulus are likely due to evolved induced responses to detection of predatory bats.
