"Lots of things fly at night," says Harlan Gough, a wildlife biologist with the U.S. Fish and Wildlife Service. Nightfall can set the stage for an acrobatic high-stakes drama in the air — a swirl of ...

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by ...

Sounding like a toxic moth might keep some beetles safe from hungry bats. When certain tiger beetles hear an echolocating bat draw near, they respond with extremely high-pitched clicks. This acoustic ...

Tiger beetles generate "anti bat-sonar" to prevent echolocating bats from eating them, scientists say. An experiment suggests the beetles mimic sounds created by poisonous insects that bats avoid.

For many nocturnal moths, hearing sound waves is a matter of survival in the night sky. Their ability to detect ultrasonic calls emitted by bats determines whether they escape or become prey. This ...

Researchers played simulated bat echolocation calls in the laboratory and found that egg-bearing A. nigrisigna stopped flying when exposed to high pulse repetition rates. This behavior could be ...

Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat ...
