Cicada is a cicada, commonly known as cicada. At present, there are about 2000 species of cicadas, with a body length of 2-5 cm. Two pairs of cicadas with membranous wings, prominent compound eyes and singing are male cicadas. The vocal organ at the base of the male cicada's abdomen is like a big drum covered with an eardrum, which vibrates and makes sound. Because the cicada's vocal muscles can stretch about 10,000 times per second, and the gap between the cover plate and the eardrum can play a role of * * *, so its singing is particularly loud. The female cicada is called "dumb cicada" because of her incomplete body structure and no eardrum.
Cicadas are mostly distributed in tropical areas and live in deserts, grasslands and forests. ? Cicada has a needle-like hollow mouth, which can pierce trees and suck juice. It is a large insect that sucks plants. Cicadas make courtship sounds before mating, and their eggs are laid in wooden tissues. Once hatched, nymphs burrow into the ground, inhabit the soil, and suck juice from the roots of perennial plants. It usually takes five times to molt, and it takes several years to mature. When black cracks appear on the back of cicada pupa, it begins to molt, and the whole process is about 1 hour.
