To elude bats, a moth keeps its hearing in tune

It has been known for over 50 years that moths can hear the ultrasonic hunting calls of their nocturnal predator, the bat. Moth ears are among the simplest in the insect world—they have only two or four vibration-sensitive neurons attached to a small eardrum. Previously, it was thought that these e...
