...beyond the limit of human hearing, the high-pitched hunting cry of the bat makes the dark dangerous for night-flying insects. Bat chirps bounce off their tiny bodies like sonar pulses, giving their position away to the swooping enemy. Yet despite the bat's delicate detection equipment, many an insect escapes-and scientists have long wondered why. In the current issue of the American Scientist, Biologists Kenneth Roeder and Asher E. Treat explain how they pried into the defensive secrets of the noctuid moth, an insect that has demonstrated singular evasive skill...
...took a live moth, attached delicate wires to the nerves leading out of one of its ears, and connected the little insect to an amplifier and an oscillograph. Then they turned on an electronic generator that gave out brief bursts of ultrasonic sound-a reasonable imitation of a prowling bat. Even where the man-made beeps were too weak to be detected by man-made microphones, the moth's ear responded with electrical signals. When the imitation bat sounded louder, as if it were closing in, the moth's ear responded more strongly, covering the face...
Having analyzed the moth's sonar-detecting apparatus in the laboratory, Roeder and Treat tried it out in the field against real bats. They set up their apparatus on a Massachusetts hillside, and at nightfall their wired moth began to detect the ultrasonic cries of bats. From the traces on their oscillograph, the biologists could tell whether an invisible bat was approaching or flying away. Later, when Roeder and Treat turned on a powerful floodlight, they could watch the bats diving on their prey and hear, through the captive moth's ear, the bats' searching sonar beeps...
