It is usually about five or six centimeters long. Their needle-like hollow mouths can pierce into trees and suck sap. There are also different species of cicadas that are similar in shape but different in color.
The cicada has three less sensitive eyespots in the middle of its eyes, and the wings are simply distributed with thin tubes that act as supports.
2. Characteristics: The larvae of the cicada live in the soil, suck the sap of the roots of the plant, weaken the tree, make the branches die, and affect the growth of the tree. The larvae of cicadas live in the soil all their lives.
When it is about to be feathered, it burrows out of the surface at dusk and at night, climbs on a tree, and then grabs the bark of the tree to molt and feather. When a black crack appears on the back of a cicada pupa, the molting process begins.
The whole process takes about an hour. At the end of June, the larvae begin to emerge into adults, with a maximum lifespan of about 60 to 70 days. In late July, the female adults begin to lay eggs, and the peak oviposition is in early and mid-August, and the eggs are mostly laid on branches with a thickness of 4 to 5 mm. Summer in the trees loud and loud,

Cicadas are insects. Cicadas belong to the winged subclass of the class Insecta, which will change from pupae to adults in June and July each year, and then lay eggs within a few days, starting from eggs, until the nymphs live underground until the last time they shed their shells and become adults, which usually takes one to two years.

Cicadas are insects. It is a common name for insects in the cicada family, and there are many types.
Grasshopper cicada is also known as Zhi, Ma Ji, black old wow, the larval stage is called crawling, climbing monkey, cicada monkey, knowing monkey, knotted monkey, beef cattle, knotted turtle, fairy or cicada turtle, for the homoptera cicada family medium to large insects, about 2000 species. The body is 2-5 cm (inch) long, with two pairs of membranous wings, compound eyes prominent, and three single eyes. There are two species in the family Mantis, commonly known as hairy cicadas, which are only found in southern Australia.
Cicadas are mostly found in the tropics, inhabiting deserts, grasslands and forests. In addition to the species of the genus Mothcia that appear in midsummer every year, there are also periodic cicadas. The most famous periodic cicadas are the 17-year-old cicada and the 13-year-old cicada, which appear once at certain intervals in a certain area.
Growth and development of cicadas
Some species are easier to identify by their vocalization, behavior, and morphology. The male cicadas of each species produce three different kinds of songs, which are regulated by daily weather changes and other male songs; courtship sounds before mating; The gruff sound of being caught or frightened and flying away. The larvae live in the soil and feed on the sap of the roots of the plant, and the adults feed on the sap of the upper part of the plant.
The cicada's pupae spend the first two or three years of its life underground, perhaps for a longer period of time. During this time, it sucks the liquid from the roots of the tree. Then one day he broke through the ground and found a tree to climb with his survival instinct.
After several years of slow growth, the cicada pupa crawls out of the ground as a reservoir of energy. Its front paws, which are used to burrow, can also be used for climbing. When molting, it is generally chosen to be dark and rainy, because cicadas need a humid place to molt, otherwise they will die of lack of water.
Spiders are not insects, but belong to the class Arachnids among arthropods. Flies, mosquitoes, crickets, bees, etc., are our most common insects, and they belong to the class of insects in arthropods. Spiders and insects belong to different branches in arthropods.
