Sonar wars in the night skies (NewsObserver.com)
"Conner began to study bats and moths together and learned that just like military aircraft, at least one species of tiger moth can jam enemy sonar by producing a sound at the right frequency. Moths, of course, found it first. Jamming sonar means the moths interfere with their enemies' fine-tuned way of bouncing sound off objects to navigate. However, the b. trigona moth seems to thwart its enemy, the bat, every time, and the military still can't claim that rate for foiling anti-aircraft missiles. Conner has only studied the one type of moth but has never seen a moth get eaten after producing the high frequency racket. So, can the military learn a thing or two from a moth?"
