Chapter one provides an overview of this arms race. Bats capture night-flying insects using highly sophisticated echolocation and flight. Most macrolepidoptera are eared and bat echolocation calls stimulate evasive flight reactions. Some tiger moths (Lepidoptera: Erebidae, subfamily Arctiinae) also respond to bats with trains of ultrasonic clicks which 1) truthfully or deceitfully warn bats of a distasteful prey, 2) startle bats, or 3) interfere with or jam bat sonar. Evidence is strong for the warning and startle hypotheses, although the startle effect is ephemeral. The jamming hypothesis has not been confirmed to occur in nature. en Wake Forest University anti-predator defenses bioacoustics echolocation predator-prey sensory ecology Sonar Jamming in the Bat-Moth Arms Race Dissertation Conner, William E Ashley-Ross, Miriam Browne, Robert Hristov, Nickolay Fahrbach, Susan Biology 2013-12-06 open.access
