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 ...

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 ...

"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 ...

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.

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 ...

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 ...

A new study from the Smithsonian Tropical Research Institute used a robot to mimic common big-eared bats' echolocation skills ...

Scientists from diverse universities conducted controlled experiments to determine how big-eared bats detect insects ...

When night falls, a high-stakes acrobatic drama takes the stage, a swirl of bats hunting insects, trying to outmaneuver each other in aerial pursuit and escape. Science reporter Ari Daniel has the ...
