The call of the mockingbird is: "Knowing Knowing".

The male cicada will chirp, its articulator in the abdominal muscle department, like a drum covered with a layer of tympanic membrane, the tympanic membrane by vibration and sound, due to the song muscle can stretch about 10,000 times a second, the cover and the tympanic membrane between the empty, can play a role in the *** song, so its song is particularly loud. And can take turns using a variety of different tones of voice rousing song.

The male cicadas sing every day, in order to lure the female cicadas to mate, they can not hear their own "song". Male cicadas of each species make three different calls: a rallying call, regulated by daily weather changes and the calls of other males; a pre-mating courtship call; and a coarse, harsh call when they are caught or startled and fly away.

Female cicadas have incomplete musical instruments and are unable to vocalize, so they are "mute cicadas". Some species are easier to identify by sound, behavior, and morphology.

The cicada transforms from nymph to adult in June to July each year and then lays its eggs in just a few days, a period of time that usually lasts between one and two years, from the time the egg is laid, through the process of the cicada's life in the ground, and the final shedding of its shell to become an adult that chirps loudly in the trees.

In the cicadas, their larvae are also known as "wakame", and their male cicadas will make sounds to attract female cicadas to mate with him, and it is in its pointed ovipositor tube, inserted close to the tree to lay eggs, until the next year, the larvae will not hatch, and then in the soil for several years or even more than ten years before they can break through the soil, in the long life! They have to go through many times of shelling after a shelling is also when it becomes an adult, and when it becomes an adult it will make a sound.

The sound made by the male cicada is a sharp, loud sound made by vibrating the two membranes on its abdomen hundreds of times per second. This sound helps the female cicada to locate a suitable male cicada for mating.
