Cicadas are insects in the Cicadaceae family, commonly known as cicadas. There are currently about 2000 species of cicadas, with a body length of 2-5 centimeters. Cicadas with two pairs of membranous wings, protruding compound eyes, and the ability to sing are all male cicadas. The vocal organ at the base of the male cicada's abdomen is like a large drum covered with a layer of eardrum, which vibrates and produces sound. Due to the fact that cicadas' vocal muscles can stretch and contract about 10000 times per second, and the gap between the lid and eardrum can resonate, their vocalizations are particularly loud. However, female cicadas, due to their incomplete body structure and lack of eardrums, are unable to produce sound and are known as "mute cicadas".
