CATDOLL : CATDOLL: What are the differences between katydid, cricket, cicada and cicada? ?

Cicadas and cicadas are the same species, and the differences between the other three species are as follows:

1. Different morphological characteristics

1. Grasshopper: The adult is emerald green, with a few being light brown. The antennae are well developed and 60 mm long, with 2 compound eyes and 3 simple eyes. The pronotum is wide, with a yellow edge on the lower edge of the pronotum. Each thoracic ventral plate has a pair of conical spines, with the spines on the metathorax being the largest. The appendage pattern is 4-4-4, with pads on the 1st to 3rd appendages, and the first appendage pad on the hind leg is divided into 2 blades. The hind leg has 6 spurs at the end of the tibia, 2 on the back, 4 on the ventral, and the middle 2 are smaller. The femur of the hind leg is slightly longer than the tibia.

2. Crickets: Their body color varies greatly, mostly from yellow-brown to dark brown, or green, yellow, etc. There are few with uniform body color, most of them are mottled. Their bodies are not scale-free. Their mouth shape is either undermouth or frontmouth.

3. Cicada: Cicada has two pairs of membranous wings with basically the same shape, a wide and short head with a prominent frontal lip base, and very good vision. Its compound eyes are not large and are located on both sides of the head and widely separated. It has three simple eyes.

2. Different living habits

1. Grasshopper: Omnivorous, but mainly preys on other insects. Can kill each other when hungry, females usually eat more males. Since it can prey on some pests, it should be caught and used reasonably. It is considered a pest in the tussah area. In terms of plants, in addition to eating various green plants, it also eats steamed bread, rice, tofu, steamed bread, fried cakes, etc.

2. Crickets: Crickets live in burrows, often on the ground, under bricks and stones, in earth holes, and among grass. They are active at night. They are omnivorous and eat a variety of crops, seedlings, vegetables and fruits. Some behaviors of crickets can be induced by specific external stimuli.

3. Cicada: Cicada larvae live in the soil and have a pair of strong digging forelegs. They use their piercing-sucking mouthparts to suck sap from the roots of plants, weakening the tree, causing branches to die and affecting tree growth.

3. Different distribution ranges

1. Grasshopper: Hebei mainly breeds it, followed by Henan, Heilongjiang, Jilin, Shandong, Beijing and Tianjin.

2. Cricket: all over the world.

3. Cicada: temperate to tropical regions.

Other names: katydid, katydid, katydid

Distributed in Jilin, Liaoning, Inner Mongolia, Ningxia, Shanxi, Gansu, Shaanxi, Hebei, Henan, Shandong, Jiangsu and Anhui.

The male is 35-4 mm long, and the female is 40-50 mm long. The whole body is bright green or yellow-green. The head is large and the face is nearly straight; the antennae are brown, filamentous, and longer than the body; the compound eyes are oval. The pronotum is well developed, covering the middle and metathorax, and is shield-shaped. The veins of the forewings are brown. The male has short wings and a sound organ; the female only has wing buds, and there is a saber-shaped ovipositor at the end of the abdomen, which is about 2.5 times the length of the pronotum. There is an auditory organ at the base of the foreleg, and the lower edge of the femur of the three pairs of legs has short black spines and is serrated. The hind legs are well developed and good at jumping. There are often brown longitudinal halos on the femurs,

One generation occurs each year. The insects overwinter as eggs in the soil. Adults or nymphs like to live in grain fields or bushes. They like to eat tender stems and fruits of leguminous plants. Although they are pests, people like to keep them as toys.

The mystery of French scientist Katydid's suicide by diving

In nature, katydids and other Cladoptera insects often commit suicide by jumping into the water because they cannot stand the parasites called nematodes on their bodies. Researchers have long been unclear about the specific reasons. Scientists from the French Institute for Development have finally found the answer.

According to a bulletin released by the French National Center for Scientific Research on the 3rd, when nematodes are still larvae, they will hide in the bodies of crickets or katydids. However, when the nematode larvae develop to a certain extent, they must live in water to survive their adult stage and reproduce in water. Therefore, the nematode larvae will "force" the host to leave their living environment and jump into the water.

The amazing control of nematode larvae over their hosts has aroused the curiosity of scientists. David Biron and others from the French Institute for Development have studied the differences in protein expression in the cells of katydids with parasitic nematodes and those without parasites, and also studied the differences in the expression of cell proteins before and after katydids committed suicide by diving. The results have solved the mystery of katydids' suicide by diving.

Scientists first discovered that specific proteins that control the growth of central nervous cells in katydids can control the rhythm of the katydids' day-night alternation and neural activity. After further research, they also found that nematodes can secrete chemical elements that can structurally mimic specific proteins of hosts such as katydids. The pseudoproteins generated in this way can seriously damage the central nervous system of the host, causing katydids to become abnormal and be "induced" by the pseudoproteins to jump into the water to "commit suicide."

Cricket

1. Insects

Cricket (xishuai) (Gryllulus; Gryllus) is an invertebrate, Insecta, Orthoptera, Gryllidae. It is also called cricket, and is commonly known as cricket in northern China. There are about 2,500 known species in the world, about 150 known species in China, including 50 species in Taiwan Province. (The data here is questionable: there are more than 1,400 species that have been named in the world, and more than 30 species have been named in my country.) Some species are pests of dry crops. Most crickets are small and medium-sized, and a few are large. They are yellow-brown to dark brown. They have round heads, broad chests, and slender, easily broken filamentous antennae. They have chewing mouthparts. Some have well-developed mandibles, which are good at biting and fighting. The front legs and middle legs are similar and the same length; the hind legs are well-developed and good at jumping; the tail is relatively long. The auditory organ on the tibia of the front legs is larger on the outside than on the inside. Males like to sing and fight, and there is a phenomenon of cannibalism. There are sound organs on the front wings of male insects, which are composed of scrapers, friction veins and sound mirrors on the wing veins. The forewings are raised and rubbed left and right, thus vibrating the sound mirror and producing a tone. Females are larger, with a needle-shaped or spear-shaped ovipositor and small wings.

Crickets live in burrows, often on the ground, under bricks and stones, in earth holes, and among grass. They are active at night. They are omnivorous, eating a variety of crops, tree seedlings, vegetables and fruits. Some behaviors of crickets can be induced by specific external stimuli. During a cricket fight, if the male cricket's whiskers are stimulated with fine and soft hairs, it will be encouraged to rush towards the opponent and fight hard; if its tail hairs are touched, it will be disgusted and kick back with its hind tibia to express resistance.

Common crickets (such as Beijing oil gourd) have one generation per year and overwinter as eggs in the soil. The eggs are laid singly in the soil at the edge of weedy and sunny fields, graves, and haystacks. The male insect builds a soil burrow and lives with the female insect. It likes to live in a cool, loose, and humid environment. When the insect population is too dense, they often kill each other. Peanut crickets have one generation per year in Guangxi. The nymphs overwinter in the soil burrows and emerge from the soil in March or April of the following year to harm peanut seedlings. In early June, they emerge as adults and continue to harm. In mid-to-late November, they begin to overwinter as nymphs. Adults and nymphs live in burrows as deep as 0.6 meters or even deeper. The newly built burrows are very simple, with only one escape hole. Before laying eggs, 3 to 5 branch holes are built for egg laying, and the young stems, leaves, and seeds of peanuts are searched for outside, and transported back to the burrows for storage to feed the newly hatched nymphs. Newly hatched nymphs live in groups, but after a few days they go out to look for food, each digging its own burrow.

Crickets are important agricultural pests in Northeast China, North China, the lower reaches of the Yangtze River and South China. They destroy the roots, stems, leaves, fruits and seeds of various crops, and are particularly harmful to seedlings. In the south, peanut crickets destroy 10% to 30% of peanut seedlings. They also harm corn, jute, tobacco, cotton, soybeans and cassava, often causing seedling shortages and affecting harvests.

Common crickets include:

Chinese cricket (Gryllus chi-nensis). About 2 cm long, dark brown. One generation per year, overwintering as eggs in the soil. The male has a sound organ near the base of the front wing, and sounds by rubbing the wings together. The auditory organ is located on the tibia of the front leg. It is a burrowing insect, often moving underground, on the ground or in the cracks of bricks and stones. It harms the roots, stems, leaves, seeds and fruits of plants, mostly feeding at night, biting the tender parts of plants near the ground, causing seedling failure, and is an agricultural pest.

The coffin-headed cricket (Loxoblemmus doenitzi) has a flat head with a flat front end that tilts forward, and the male's head protrudes significantly to the sides;

Gryllus testaceus has a dark black and shiny body, with yellow stripes on the inner upper part of the two compound eyes, extending to the back of the head. The forewings are light brown and shiny, and the hindwings are more developed. The female's ovipositor is up to 2 cm long. It forages at night, and both adults and nymphs harm crops such as soybeans, sorghum, peanuts, melons, and vegetables. It is distributed in many provinces across the country.

Crickets are solitary by nature and generally live independently. They will never allow themselves to live with other crickets (males also live with another female during mating season). Therefore, they cannot tolerate each other and will fight if they meet.

Crickets are known for their chirping and aggressiveness. In the cricket family, male and female crickets do not achieve a "hundred-year marriage" through "free love". The male cricket that is brave and good at fighting and defeats other crickets of the same sex will gain the right to possess the female cricket, so "polygamy" is common in the cricket family. Of course, from the perspective of biological evolution, this is also natural selection, the survival of the fittest, which is conducive to the health and prosperity of the cricket family. In addition, the chirping of crickets is also quite famous. Different tones and frequencies can express different meanings. The loud and long rhythmic chirping of crickets at night is a warning to other crickets of the same sex: This is my territory, don't invade! At the same time, it also calls out to the opposite sex: "I'm here, come quickly!" When other crickets of the same sex are ignorant of the courtesy and rashly intrude, they will chirp majestically and quickly as a stern warning. If the "ultimatum" fails, a brutal battle to seize territory and defend territory will begin. The two crickets will throw out their fangs, kick their legs and flap their wings, and fight each other with a fierceness that is no less than the most brutal hand-to-hand combat between two ancient countries.

Crickets are widely distributed, and can be found almost all over the country, and are more common in provinces south of the Yellow River. They like to live on hillsides, fields, piles of rocks and grass where the soil is slightly moist.

This insect usually starts to sing in August in summer. It usually sings most happily at 20 degrees in the wild and stops singing when the weather turns cold in late October. It has one generation per year and lays eggs in the soil to overwinter.

When a male insect meets a female insect, the sound of its chirping may become: "Chijizhi, chijizhi"; during mating, a trembling "zhi..." sound may be emitted.

Male insects are aggressive, and when two male insects meet, they first stand up with their wings and chirp to show their power, then face each other, each opening their large jaws like pincers to bite each other, and also kicking each other, often fighting back and forth for 3 to 5 rounds. Then, the loser escapes silently, while the winner stands up with his wings, proudly chirping loudly, looking very proud.

Crickets have been kept by people since ancient times because of their ability to chirp and fight. According to records, Chinese families began to keep crickets in the Tang Dynasty. At that time, whether officials in the court or ordinary people, people liked to bring their "treasures" and get together to compete in their spare time. According to research, crickets are an ancient insect with a history of at least 140 million years.

Every quiet summer night, bursts of clear and pleasant chirping can be heard from the bushes. Listen, the crickets are having a concert again! The beautiful and melodious singing of crickets does not come from their good voices, but from their wings. If you observe carefully, you will find that the crickets are constantly vibrating their wings. Is it flapping its wings to fly? Of course not, the wings are its vocal organs. Because there is a short thorn like a file on the right wing of the cricket, and a hard thorn like a knife on the left wing. The left and right wings open and close, rubbing against each other. Vibrating the wings can make pleasant sounds. During the breeding season, male crickets will vibrate their wings more vigorously, using beautiful songs to find a good mate. Among them, the king of songs is the long-jawed cricket. The body length can reach about 20 mm, and the antennae are about 35 mm long. Because of the two large teeth protruding forward, it is called the long-jawed cricket, commonly known as Kes.

In addition to being good at singing, crickets are also very aggressive. Fighting is a contest between male crickets. When crickets meet, they will use their antennae to identify each other. When two males meet, they will show their two big teeth to compete with each other. However, when a male and a female meet, the scene is different. The two crickets will be affectionate and express their admiration for each other.

In ancient times, cricket fighting for entertainment was usually carried out in pottery or porcelain cricket jars. When two males met, a fierce battle began. First, they flapped their wings and chirped violently, one to cheer themselves up, and the other to destroy the opponent's prestige, and then they started the duel with their teeth bared. They pushed their heads, kicked their feet, rolled their long antennae, and kept rotating their bodies, looking for favorable positions and bravely attacking. After a few rounds, the weaker one was dejected and defeated, while the winner raised his head and chest, arrogant, and asked for credit and reward from the host. The most combative one is the black-headed cricket of the cricket family, which is called the black-headed general by the folks. A good cricket that can both chirp and fight well will not only be the glory of the cricket fighter, but also the king of the cricket kingdom. However, when playing with crickets, you must be careful not to lose your ambition.

Grasshoppers and crickets [scientific name: crickets] are both insects but not in the same category. Zhiliao is the common name for cicadas, which are derived from golden cicadas. Grasshoppers live in the grass or in the fields. Due to the widespread use of pesticides in recent years, there are very few grasshoppers in the fields. Cicadas live in trees. The larvae of cicadas are bred underground for about three years. Grasshoppers and cicadas are two different things.

The katydid is big and green.

Crickets are small and black.
