Insect information in summer

Insects in summer are: cicada, cricket, slug, locust, weaver girl and grass bell.

Cicadas live in temperate to tropical regions of the world (about 2000 cicada species have been recorded). Some species distributed in desert areas, when their body temperature is overheated, will discharge excess water from the back plate (tergum), thus achieving the effect of cooling and dissipating heat.

Cicada larvae live in the soil and have a pair of powerful digging front legs. Sucking the sap from the roots of plants with mouthparts weakens the tree, makes the branches die and affects the growth of trees.

This male cicada can sing. Its vocal organ is located in the abdominal muscles, and it is covered with an eardrum like a drum. The eardrum vibrates and makes a sound. Because the vocal cord muscles can expand and contract about 65,438+0,000 times per second, and the cover plate and tympanic membrane are empty, which can play a role of * * *, so its singing is particularly loud.
