Imagine flying in complete darkness. You are guided by sound. A ping returns and in an eye blink, you swoop a juicy moth into your hand-wing, then tail, then mouth. The next one isn’t so easy. A barrage of clicks and your sonar is momentarily disabled. You’ve been jammed by a tiger moth.


Bats are military experts. They invented jamming, stealth and dogfights millions of years before us. They are also incredibly important to our ecosystems. They consume pest insects by the ton, pollinate flowers that give us tequila, and disperse seeds that help regenerate tropical rainforests.


Follow along as we uncover the secret lives of bats.

Research Highlights

Can Bats Fly Without Echolocation?

Surprisingly, the answer appears to be yes. Could this explain why thousands of bats are killed at wind turbines?

Stealth Echolocation

Insects have specialized ears that make sonar calls a dead give-away. That's why some bats go quiet.

Moths Jam Bats

Tiger moths blast bats with ultrasonic noise that momentarily interferes with their sonar.
