What are the larvae of a cicada and where do the larvae of a cicada live?

Cicada larvae: live in the soil and have a pair of strong digging forefeet. The sap of the roots of the cicada plant is sucked by the piercing and sucking mouthparts, which weakens the tree momentum, makes the branches die, and affects the growth of the tree.

Usually stay in the soil for a few years or even more than ten years, such as 3 years, 5 years, and 17 years, these numbers have one thing in common, they are all prime numbers.

This is because there are very few factors in prime numbers, and when they drill out of the soil, they can prevent them from drilling out with other cicadas and competing for territory and food. 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 the cicada chrysalis.

When a black crack appears on the back, the molting process begins, the head comes out first, then the green body and folded wings are revealed, and it stays for a moment to harden the wings and darken the color, and then it begins to take off. The whole process takes about an hour. At the end of June, the larvae begin to emerge into adults, and the newly emerged cicadas are green and have 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. In summer, they make loud noises in the trees, suck the sap with a needle pricking mouthpiece, and the larvae inhabit the soil and suck the sap from the roots, which is harmful to the trees.

The scientific name of the larva is Zen pupae, the restaurant is called Jin Chan, the cicada pupa is rich in nutrition, delicious taste, has become a delicacy of people, and fried golden cicada is a famous dish.

There are many common sayings, which are different from place to place: "know the monkey", "know the ghost", "borrow the ghost", "climb the branch", "climb the rue".

Knowledge: Cicada larvae lurk underground and live on the sap from tree roots, which we generally do not see. The ancients had never seen how the larvae of cicadas reached the ground, so they believed that cicadas were transformed from the larvae of dung beetles or beetles.

The legend of "dung beetles turning into cicadas" was widely spread in ancient times, and even the "Treatise on Balance", which is known for its rigor, also said: "Grubs turn into reproduction, and reproduction turns into cicadas." "Grubs" are beetle larvae, and "rebirth" is freshly drilled cicadas.

Actually, cicada larvae hatch from eggs laid on branches by female cicadas. The deceptively simple process of moving them from branch to ground and from ground to branch takes them almost a lifetime.

Characteristics of cicadas in "Insects":Cicada larvae live in the soil and feed on the sap of plant roots, weakening the vitality of the tree, causing the death of branches and affecting the growth of the tree. The larvae of cicadas live in the soil throughout their lives.

When it is about to surface, burrow out of the water at dusk and night, climb trees, then grab the bark, molt and surface.

In summer, the trees cry loudly and suck the sap with a needle mouthpiece, and the larvae inhabit the soil and suck the sap from the roots, which is harmful to the trees. There are also different species of cicadas that are similar in shape and different in color. The cicada has three less sensitive eyespots between its eyes and simple supporting tubules on its wings.

The soprano singer of the cicada family is a type of cicada called the "double drummer".

It has large annular vocal organs on both sides of its body, and in the middle of its body is a disc that can be opened and closed inside and out. The opening and closing speed of the round sedan car rental plate is very fast, which is also the reason why the chirping of the cicadas is shaking. Cicada is a tireless singer who sings loudly for happiness.

Distribution:

It is found in temperate and tropical regions, inhabiting deserts, grasslands and forests. In addition to the species of the genus Moth Cicada, which appear in midsummer every year, there are also periodic cicadas. The most famous periodic cicadas are the seventeen-year-old cicada and the thirteen-year-old cicada, also known as the prime cicada, and because the life cycle is prime, it will not encounter the natural predators encountered in the previous generation.

Periodical cicadas occur once in a certain area at certain intervals, when dozens to hundreds of black-brown cicada larvae emerge from the soil and emerge together, which is very spectacular. Some species are easier to identify by their vocalization, behavior, and morphology.
