The description of the appearance characteristics of the cicada in the book of insects:The cicada is a large plant-sucking insect that is usually about five or six centimeters long. Their needle-like hollow mouths can pierce the body of the tree and suck the 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.

The larvae of cicadas live in the soil, sucking the sap of plant roots, weakening the tree, causing the branches to die, and affecting 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 the cicada chrysalis.

When a black crack appears on the back, 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. 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.

1.The cicada has two pairs of membranous wings, the head is broad and short, with a distinctly prominent frontal-labial base, the compound eyes are located on both sides of the head and are very separated, there are 3 single eyes, the antennae are bristle-like, the mouthparts are elongated, the thorax includes the anterior thorax, the middle thorax, and the hind thorax, each with a pair of feet, the abdomen is long and conical, with a total of 10 abdominal segments, and the 9th abdominal segment becomes the caudal segment.

The shape of the cicadaThe body length of the cicada is 2 5 cm (inch).

The cicada has two pairs of membranous wings, the shape is basically the same, the head is broad and short, with a pronounced protruding frontal lip, its vision is quite good, the compound eyes are not large, located on both sides of the head and very separated, the compound eyes are prominent, and there are 3 in one eye.

Similar in shape and varied in color, cicadas have three less sensitive eyespots in the middle of their eyes, known as single eyes, with thin tubes that simply support them on their wings.

Nutritional value of cicadas1. Cold, fragrant, with the functions of dispersing wind and promoting lungs, relieving fever and calming shock.

2. It is nutritious and tastes good.

3. The cicada body is rich in nutrients, with a dry protein content of more than 70% and a high protein content.

4. The fat content of cicadas is about 7%.

5. The content of vitamins and various beneficial trace elements of cicadas is higher than that of ordinary meat foods, and the nutritional value is rich.

The appearance of the cicada is characterized by:

The cicada has a pair of large compound eyes, located on either side of the head, with three punctate monoculars in the middle. Its antennae are short and stiff, like bristles. At the same time, the cicada has two pairs of mmenous wings, which are essentially the same shape, with a broad, short head with a distinctly prominent frontal labial base.

Also, the adult body length is mostly between 2-5 cm.

Characteristics of the life of cicadas

The larvae of cicadas live in the soil, and after the larvae become adults, they will live on trees. They are louder in summer and feed mainly on tree sap.

Adult cicadas like to suck the sap of trees, and using the stinging mouthparts to suck can weaken the tree, cause the branches to die, and affect the growth of the tree. At the same time, male cicadas can chirp, and each cicada's call is different. Generally, the cicada's articulator is in the abdominal muscles, like a large drum covered with a layer of eardrum, and the eardrum is vibrated to make sounds, while female cicadas do not chirp.

Cicadas are mainly distributed in temperate and tropical regions, inhabiting deserts, grasslands and forests, and have a wide distribution range.
