"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 ...

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 ...

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.

US researchers have developed palm-sized drones that use bat-inspired ultrasound and AI to navigate through fog, smoke, and other challenging conditions. The breakthrough by a team at Worcester ...

With perhaps the kinkiest alarm system in the animal kingdom, hawkmoths rub their genitals to create ultrasound bursts that might drive away bats, researchers say. Subscribe to read this story ad-free ...

What do bats, dolphins, shrews and whales have in common? Echolocation! Echolocation is the ability to use sound to navigate. Many animals, and even some humans, are able to use sounds in order to ...

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 ...
