Cicada, also known as cicada, is black and old, and its larval stage is called cicada monkey, reptile monkey, cicada monkey, turtle or cicada turtle. Is it a medium and large insect cicada of Homoptera? About 1, 500 species. Body length 2? 5 cm (0.8? 2 inches)? There are two pairs of membrane wings? Prominent compound eye? Three in one eye. There are two kinds of cicadas? Commonly known as cicada, it is only distributed in southern Australia. Does the male cicada have an eardrum at the base near the abdomen? When vibrating the membrane, it will make a loud noise. Most North American cicadas make rhythmic ticking or purring? But some species have beautiful voices. Some species are easier to distinguish in singing, behavior and morphology? The male cicada of each species makes three different songs? Collecting sound? Adjusted by daily weather changes and other male cicadas? Courtship before mating? The harsh sound made when caught or afraid to fly away. Cicada's eggs are often laid in woody tissues? Nymphs burrow into the ground as soon as they hatch? Suck juice from the roots of perennial plants. Usually after 5 molts? It takes several years to mature. How many women are there? Laying eggs will damage saplings. Cicadas are mostly distributed in the tropics? Habitat in deserts, grasslands and forests. In addition to the three-volt cicada that appears every summer, there are also periodic cicadas. The most famous periodic cicadas are 17 cicada and 13 cicada (magic cicada)? It happens regularly in a certain area. Some species are easy to distinguish in singing, behavior and morphology. The male cicada of each species makes three different songs? Collecting sound? Adjusted by daily weather changes and other male cicadas? Courtship before mating? The harsh sound made when caught or afraid to fly away. The larval stage of cicada is called cicada monkey, cicada monkey or cicada turtle. The biggest cicada is 4? 4.8 cm? The bottom of the wings is dark brown. Shouting in the trees in summer? Sucking tree juice with needle mouthparts? Larvae inhabit the soil? Suck juice from the roots? It is harmful to trees. The shell of cicada can be used as medicine. Cicada is a large plant that sucks insects. It is usually about four or five centimeters long. Their hollow mouths like needles can pierce trees? Suck the sap. There are also different kinds of cicadas? They are similar in shape, but different in color. There are three less sensitive points between cicada eyes? The supporting tubules are simply distributed on the two wings. These are the primitive characteristics of ancient insect populations. The high note in the cicada family is a cicada called "double drummer". It has large ring-shaped vocal organs on both sides of its body? The middle part of the body is a disk that can be opened and closed inside and outside. Is the disk opening and closing fast? That's the sound of a quivering cicada. Is there a lack of change in this voice? But it's much louder than the jungle canary. The cicada spent the first two or three years of its life underground? Maybe longer. During this time? It sucks liquid from the roots of trees. And come out one day? Find a tree and climb it by survival instinct. After several years of slow growth, cicada pupa. Climb out of the ground as energy storage. Its front paws for digging holes can also be used for climbing. When there are black cracks on the back of cicada pupa? The process of molting begins. Molting is controlled by hormones. Is the front leg of cicada pupa hooked? Like this? When an adult comes out of an empty shell. It can be hung firmly on the tree. Cicada must face the tree vertically? This is very important. This is for the normal development of adult wings? Otherwise the wings will be deformed. Cicadas use pupa shells as the basis? Get rid of yourself slowly? It's like climbing out of armor. The whole process takes about an hour. When cicada's upper body is free? It hangs upside down and spreads its wings. At this stage Cicada's wings are soft? They spread through the body fluid tubes in the body. The body fluid tube spreads its wings by the pressure of liquid. When the liquid is pumped back into the cicada. The spread wings hardened. What if cicadas are disturbed in the process of spreading their wings? This cicada will be disabled for life? Maybe you can't fly at all. In Shawan, Xinjiang? The way cicadas are unearthed is different from what everyone knows. Just like in the Central Plains? Does the cicada pupa crawl out of the ground at dusk or just at night? Find a place to attach a small tree or other plants? Hold on tight, okay Start molting. And in Shawan? When it is the hottest at noon, cicadas come out directly from the ground? Find a small bush nearby and climb it. When you first came out of the ground. Bright yellow? Smaller at noon? The sunshine is very strong? The cicada turned black on the bush? You can spread your wings and fly away when it is completely dark. So there are two differences? One o'clock is time? Are you familiar with dusk or night? And it's noon in Xinjiang? Another point is that cicadas in Xinjiang have no shells when they are unearthed. When cicadas are thirsty and hungry, they always use their hard mouthparts-a slender hard tube, stick their mouths into the trunk to suck the juice all day, and suck a lot of nutrients and water into their bodies to prolong their lives. Suck plant root juice? Weaken the tree? Let the branches die? Affect the growth of trees. Grasshopper larvae live in the soil all their lives. When it's about to feather. Drill out of the surface at dusk and night? Climb a tree? Grab the bark? Molting and eclosion. End of June? Larvae began to emerge as adults? The longest life is about 60? 70 days in late July? Female adults begin to lay eggs. Early and middle August is the peak of spawning? Eggs in 4? Branches 5 mm thick. When female adults lay eggs. Pierce the bark with an ovipositor first? Insert the ovipositor into the branch tissue? Causing claw-like egg holes? Then lay eggs in xylem. There are 6 eggs in each spawning hole? Eight tablets. Cicada eggs on the branches? More than 90 pills. Where is the severity of this bug? At the end of autumn, it is common that the trunk is full of dead branches. The laid eggs will hatch in the middle of June of the following year. After the larvae hatch? Fell off a branch to the ground? Then drill into the soil. How many years do larvae live in the soil? * * * molt 5 times. Whenever the weather is warm in spring? Larvae move upward? Suck the juice of plant roots? When autumn comes, winter comes. And go deep into the soil? To avoid the cold. Are larvae mostly white or yellow? Very soft? The forehead is obviously enlarged. Older larvae are harder? Yellow brown? Wing buds are well developed? From the top of the head to the middle of the chest? There's a molting line? The crack line when it is an eclosion adult. Why do cicadas like to sing passionately? Screaming at the top of your lungs? Fabres, a famous French entomologist, was puzzled. He lived in his 90 s? Dedicated to entomology research all his life? Write down a research collection of more than 6.5438+0 million words-"Insects". He has been observing cicadas for many years? And described it in an extremely vivid and detailed way. Is that how he describes cicada singing? "In the cavity behind the cicada? Use a musical instrument like a cymbal. Isn't that enough? And put a castanet on your chest? To increase the intensity of the sound? Is this cicada to satisfy the love of music? Really made a great sacrifice. Because of this giant castanet? Let the living organs have nowhere to put them? We had to squeeze them into the smallest corner. Shrinking internal organs for musical instruments? This is of course an extreme passion for music. " However? Fables, in order to find out why cicadas keep pulling cymbals? Sing hard? Didn't it hear its loud voice at all? Afraid that others have never heard of it like themselves? Just raising your voice on purpose? So what? He conducted an experiment? Let's see if the male cicada can hear the sound. He stood behind the male cicada? Speak loudly at close range? Blow the whistle hard? Clap your hands? Hit stones with stones ... scare cicadas with all kinds of noise. But cicadas continue to sing indifferently. You really don't listen to what you say, do you? I can only sing cicadas. What happened afterwards? Fabrice simply found two muskets to beat the beast? Full of gunpowder? Launch again and again next to cicadas? Sounds like thunder? But the "singers" are still singing leisurely? Not even a little fear and anxiety. So Fabres came to the conclusion? Male cicadas have no hearing? It can't hear anything around it? You can't even hear yourself screaming at the top of your lungs? He is really deaf.
