Features Som da Cigarra

Cicadas belong to the Cicadidae family of the order Hemiptera (a group of insects to which bedbugs belong).
In addition, they are easily recognized by their shape, size (which varies from 15 to 66 millimeters in length) and colors that include brown, green, black or grayish.A distinguishing feature is that three black dots placed in a triangle shape can be seen on the top of its head, which are actually three simple eyes or eyespots, which facilitate frontal vision.On the other hand, it is believed that the sound produced by some species can act as a defense against predatory birds.
By the way, some of these sounds are even loud enough (120 decibels) to cause pain to the human ear.In short, there are more than 3,000 species of cicadas in the world.
Thus, these can be roughly divided into annual cicadas, which always appear in summer, and periodic cicadas, whose life cycle occurs every 13-17 years.
