Every night a battle between bats and moths that feed starts. While the first launch ultrasound to navigate and locate your "dinner", many moths have developed an "ear" fine that allows them to detect these ultrasounds and flee quickly before being attacked. Only members of a species of bats, barbastelle, get to hunt them with relative ease. But how?
To averigaurlo, Matt Zeale and colleagues at the School of Biological Sciences at the University of Brystol measured how insects detected a potential predators by collecting activity of the auditory nerves of moths as "track the position of the bats" .
"Record activity ears of moths in nature has revealed exciting data," says Zeale, which found that while the moths can detect other types of bats over 30 meters away, are 100 times Barbastella silent, as they have developed a "whisper" that makes them detectable only 3.5 meters ... Too close for insects to flee, the scientists explain in the latest issue of the journal Current Biology.
