Crickets Singing
The characteristic chirping sound of the cricket comes not from vocal cords but from the insect's wings. A male cricket scrapes the sharp ridge on the left front wing (left) against the flat "mirror" area of the right front wing (center). His song attracts females, which use their legs to hear it. Just below a cricket's knee joint, a membranous organ called a tympanum (right) detects sound vibrations. яндекс.ћетрика
