Singing Crickets
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. Just below a cricket's front knee joint, a membranous organ called a tympanum (right) detects sound vibrations. яндекс.ћетрика
