Adults are green and a few are light brown. The antenna is 60mm developed, with 2 compound eyes and 3 monocular eyes. The front chest backboard is wide, and the lower edge of the backboard has a yellow edge. There are 1 pairs of conical spines in the thoracic web, and the posterior thoracic spine is the largest.

Attachments 4-4-4, 1-3 are provided with foot pads, and the first attached foot pad of the hind foot is divided into two pieces. The distal distance of tibiofibular joint of hind foot is 6, the back is 2, the abdomen is 4, and the middle is 2. The hind leg joint is slightly longer than the tibiofibular joint.

Adults are 80 ~ 100 mm long, often green or yellowish brown, with small males and large females, and reddish longitudinal stripes on their backs. The medial rib line, lateral rib line and abdominal edge of the anterior chest backboard are reddish. The front wing is green or hay-colored, with reddish stripes along the elbow vein, or the midvein has dark brown longitudinal stripes, and the rear wing is light green. Nymphs are similar to adults. Eggs are lumps. ?

There are more than 5000 kinds of grasshoppers in the world, many of which can not only jump, but also fly. Under their narrow and thick front wings, there are a pair of wide and thin rear wings. When the grasshopper flies, it lifts its front wing and beats its back wing. However, they jump with their hind feet instead of flying with their wings.

Second, different living habits.

Most adults emerge in the morning, and mate after 7- 13 days, lasting about 30 minutes. The male secretes a milky white sticky testis with a diameter of 65438±00mm, which is attached to the female genitalia, and the mating is over. At this point, the female insect's abdomen bends forward, and she bites the testis and squeezes the sperm into the seminal vesicle. If she doesn't eat the testis, she can't produce fertilized eggs.

Yin Yan can mate many times in his life. The female begins to lay eggs 13-20 days after mating, and the spawning period is very long, and the weight can be increased by about 3 times after pregnancy. When laying eggs, the abdomen is lifted upward, the ovipositor tube is vertically inserted into the upper part, and the ovipositor flap moves up and down, so that the eggs are laid in the soil and scattered.

After spawning, pull out the spawning tube, forcibly bounce the soil back to close the spawning hole, and then continue to spawn. Oviposition occurs more during the day than at night, starting in early July, peaking in August and ending at the end of September.

Grasshoppers usually emerge into adults from July to August every year. Male insects will die soon after mating with male and female adults, while female insects eat a lot and accumulate nutrition. 1 week later, the eggs in the abdomen matured and began to lay eggs. Generally, it is laid in dry, slightly high mortar mixed with various weeds, where there is a certain humidity and loose soil layer, which is conducive to locust spawning and hatching.

Generally, it occurs in the farmland beside the weedy ditch. Every year 1 generation. Adults lay eggs in the soil, the eggs are blocked and encapsulated, and they overwinter in the soil with their eggs.

Third, the types are different.

Fruit is widely distributed in China. From the perspective of appreciation, Guo Guocan can be divided into four countries: Qingguo, Heiguo, Shanqing Guo, Caoguo and Caoguo. According to the origin, it can be divided into north and south, and the north is better than the south.

Guo in the north is divided into Guo Jing Guo, Ji Guo Guo, Jin Guo and Lu Guo. Guo is also called Guo. The most famous Guo Yan pot is the Dashan pot in Anzigou, which is famous for producing big black iron pots.
