Lifestyle
The cicada fly feeds on plant sap, the larvae feeds on roots. They amaze the plant with numerous crowds, which bring significant damage to agriculture.After the larvae emerge from the ground, they hastily move to the green part of the trees.
On a note!
On 1 square. m. area can accumulate about 300 individuals.
In tropical countries, the emergence of a new generation of cicadas is a real feast for birds, many animals. After a few days, well-fed enemies leave to digest protein foods, the remaining cicadas begin mating season.
Males make melodious loud trills to attract females. The chirping is so loud that the sounds of dragonflies, grasshoppers fade before it. Residents of tropical areas compare the sound of a cicada fly with a chainsaw roar, a locomotive beep. Noise is irritating to the nervous system.
In the overwhelming majority, the song is played exclusively by the male, females silently mate, lay eggs, so as not to attract enemies. Appearance with brown, green shades and transparent wings makes it easy to hide in the thickets of shrubs and trees. Even with impressive size, a fly is hard to see.

The source of the loud sound is at the end of the body. A membrane is placed there, which is set in motion by the muscles, followed by a resonator, which amplifies the issuing chatter several times.The membrane for a second fluctuates about 600 times. In the tropics, it's just a deafening sound.
The mating period lasts about a week. The male after mating lives for about 14 days, the female can live up to 2 months. During this time, it lays around 2 thousand eggs. Locals compare the appearance of adult larvae with a locust invasion that destroys everything in its path.
Special singing
The loudest singers in the world emit about 6 kinds of melodies. This is not only a call for fertilization, a sign of the beginning of the marriage period, but also scaring, warning, engaging, communicating.
Thanks to a special song, different types of cicadas are not confused with each other. The female flies to the song of the male of her family. Determine with accuracy the location of the male, the female is capable of half a meter. The female sits down, flaps her wings, secretes the pheromones that the male feels, and goes in search of her.
The cicada's auditory organs are identical in structure to crickets, but more sensitive. Able to distinguish different warning signals that attract sound. The males of the Caucasian mountain cicadas make a sound-crying, which in the far distance attracts females. In the short run for other males, it sounds like an aggressive warning.In this way, each male marks the area of his possessions. In the event of which rushes into battle.
