Abstract |
"The appearance of echolocating bats approximately 65 million years ago presented a life-or-death challenge to nocturnally active insects, particularly those that fly at night. In response, ultrasound-sensitive ears and bat-avoidance behaviors have evolved repeatedly in insects. Avoidance responses include steering away from a distant bat, last-chance maneuvers such as diving to the ground or flying erratically to avoid capture in close encounters, and sound production to startle the bat, to warn it of the prey’s distastefulness or to interfere with the bat's ability to echolocate. Some bat-avoiding insects use ultrasonic signals for intraspecific communication, presenting them with the challenge of discriminating between potential predators and mates. Evolution of the predator–prey relationship between bats and insects is ongoing, with each participant adopting new strategies to counter those of its opponent."
