tymbal
Quick Summary
The tymbal is a vibrating membrane found in the shrilling organ of a cicada. This organ is part of a complex sound-producing mechanism in certain insects, particularly in the order Homoptera, which includes cicadas, leafhoppers, and treehoppers.12
Cicadas use their tymbals to create sounds, primarily for mating calls. The male cicada contracts a tymbal muscle, which distorts the membrane, producing a click. When the muscle relaxes, the tymbal springs back. Rapid contractions and relaxations create a continuous sound. These sounds, known as stridulation, can vary between species and are crucial for identification and mating rituals. Female cicadas do not possess sound-producing organs.23
