"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 ...

US researchers have developed palm-sized drones that use bat-inspired ultrasound and AI to navigate ...

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 ...

To help small aerial robots navigate in the dark and other low-visibility environments, my colleagues and I developed an ...

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 ...

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 ...
