| Summary | The behavioral response of the tiger beetle, Megacephela Carolina Carolina L. to intense ultrasound stimulation was studied. These tests utilized a fixed 40 kHz, 150 dB signal to represent and simulate, generically, the echo locating calls of insectivorous bats, which are potential predators of the insect. The tests were designed to: 1) determine if the insect could detect intense ultrasound, 2) investigate the acoustic startle response (ASR) behavior of the insect and 3) determine the location of the tympanal hearing organs associated with the ultrasound detection--through ablation techniques and subsequent light-microscopic and scanning electron microscopic investigation. Results revealed the presence of tympanal hearing organs on the first abdominal tergum. The insect does respond to intense ultrasound stimulation with a host of ASR behaviors, which suggest the insect has evolved hearing organs as a direct result of the hunting pressures exerted by insectivorous bats. |
