What kind of insect is this?

Beetles ... what can you think of? Dung beetles? Longicorn? Ladybug? Or bitch? In fact, there are countless species in Insecta, many of which are unknown to most people. As for insects, in my eyes, there is no distinction between "beneficial insects" and "pests". The so-called "beneficial insects" and "pests" are defined around human beings. In nature, every species has its meaning and inevitability of existence. The natural law of "survival of the fittest" in nature is constantly being "changed" with the development of human beings, which makes the insects that can be seen around us gradually disappear.

One-horned fairy is a common large beetle in some places, belonging to Insecta-COLEOPTERA-rhinoptera. One-horned fairy can be a beneficial insect or a pest, and moderate amount will not cause forest damage; If the number is too large, adults will do serious harm to trees. I won't discuss this topic here. It (unicorn) is famous for its majestic and powerful unicorn horn. Because of its forked top, it was named as the double-forked rhinoceros beetle in China, commonly known as unicorn. One-horned Fairy: The Latin nomenclature of Allomyiina dichotoma (Linnaeus, 177 1) is more accurate at present.

Unicorns are mighty and handsome! Why is it called Hercules If magnified in equal proportion, unicorns can lift more than 5 tons with their horns, so they are naturally powerful people in the insect world, but people often only see the beautiful side, but always ignore its unattractive side. Just like gloating, no matter how beautiful the front is, you can't hide a bare and dull "ass" in the north. So are unicorns. In the larval stage, they are all displayed in the form of a super-large white "carnivore". It seems disgusting. How can you see a rainbow without experiencing wind and rain? Without this predatory insect period of more than 8 months, how can we see the heroic unicorn adult? One-horned fairy belongs to a completely abnormal insect. Larvae and adult are completely different, and their appearance is very different.

Let's get to know these insects around us. Let's accept this ugly larva slowly. Gradually, you will find that they are actually cute, fleshy and stupid ... let's talk about unicorns first!

Love insects, love the environment and love our ecology!

Unicorn beetle

Heteropoda; unicorn beetle

Classification Scarabaeidae/Coleoptera [edit this paragraph] Appearance features do not include horns, with a body length of 40 ~ 62 mm and a reddish brown to dark black brown body color. The male has long antlers in front of his head and small horns in the center of his chest backboard. Female insects have no horns and a dull back. [Edit this paragraph] Adults with ecological habits appear in May-August and live in low-altitude mountainous areas. There is phototaxis at night.

Medium to large insects in COLEOPTERA, Scarabaeidae and Scarabaeidae. The male has horny protrusions on his chest and head, but the female also has horns on her head. Dynastes is a tropical species in the Western Hemisphere. Hercules and Neptune have large and smooth horns in their chests, which bend forward to form pincers with the horns on their heads. Poseidon one-horned fairy can be as long as 150mm(6 inches, including 56 mm [2.25 inches]). [Edit this paragraph] Physical characteristics Allomyrina dichotoma Linnaeus, also known as the two-pronged rhinoceros beetle, is large and powerful. Excluding the corners on the head, it is 35-60 mm long and 18-38 mm wide, and it is oval with a very arched ridge. Chestnut brown to dark brown body, small head; The antenna has 10 nodes, and the gill flap consists of 3 nodes. Androgyny: The male insect has an L-forked horny process on the top of his head, and an L-forked horny process in the center of his back plate, with a smooth back. The female insect is slightly smaller, and there are no horny protrusions on the head and chest, but the center of the head and face is raised, and there are three small protrusions in rows. There is a T-shaped groove in the center of the front of the front chest backboard, and the back is thicker and darker. Three pairs are powerful, with claws at the end 1, which are powerful tools for climbing.

One-horned fairy has 1 generation a year, and adults usually appear in June-August every year. Most of them come out at night and lie down during the day, which has a certain phototaxis. They mainly feed on the sap of tree wounds or mature fruits, which is harmless to crops and trees. Larvae feed on decaying wood and decaying plant matter, so most of them live in rotten hearts of trees, sawdust piles, fertilizer piles and garbage dumps, and even between the roofs of straw houses. Will not harm crops and trees. In the larval stage, the larvae shed their skin twice, which lasted for 3 years. Mature larvae are very large, milky white, about the size of eggs, and usually bend into a "C" shape. Mature larvae pupate in the soil. One-horned fairy is widely distributed in Jilin, Liaoning, Hebei, Shandong, Henan, Jiangsu, Anhui, Zhejiang, Hubei, Jiangxi, Hunan, Fujian, Taiwan Province, Guangdong, Hainan, Guangxi, Sichuan, Guizhou and Yunnan. There are records of the distribution of Korea and Japan abroad. It is especially common in areas with developed forestry and lush trees. [Edit this paragraph] The medicinal value of Kirin fairy can be used as an ornamental and a medicine for treating diseases. Male insects are used as medicine, and they are caught and dried in summer or dried after boiling water. One-horned fairy is a kind of traditional Chinese medicine, which has the functions of relieving convulsion, removing blood stasis, relieving pain, attacking poison and relaxing bowels.

65438-0976 Decostatin extracted from Andromeda grandiflora has certain anticancer effect, with high activity on solid tumor W-256 and marginal activity on P-388 lymphoblastic leukemia.

One-horned fairy is rich in resources and worth further exploration and development. [Edit this paragraph] Regarding the research progress of unicorns, on March 13, Beijing time, according to foreign media reports, the strongest animal in the world is an insect called a unicorn. Although it is only a small insect, it can move objects 850 times its own weight. Its mystery is not limited to this. Scientists have always been interested in its shell color-changing function. At present, a new study reveals the peculiar protective characteristics of its shell, and suggests that this characteristic can be used to design new "smart materials" to effectively detect humidity changes.

One-horned fairy is an unusual insect. Its shell is not only hard and strong, which can protect its exoskeleton, but also its color will change from green to black as the outside air gets wet. Researchers from Namir University used the latest scanning electron microscope imaging technology to study the color change characteristics of unicorn shell, and used spectrophotometer to analyze how the shell structure interacted with light.

In the case of light interference, the unicorn's shell will become green. When water penetrates into the porous layer of the shell, it will destroy the light interference and cause the shell to turn black. The researchers tested the dried shell specimens of unicorns in the laboratory. One-horned fairy usually lives in the rainforest environment of Colombia, Venezuela, Peru, Ecuador, Bolivia and Brazil. At present, this mysterious insect still keeps many mysteries. For example, although the shell sample of the dead one-horned fairy can show the color change with the air humidity after drying, the living one-horned fairy may not necessarily have the same reaction.

As for why this insect changes color, it is still an unsolved mystery. Some researchers speculate that this is a protective measure. In the rain forest at night, when the humidity increases, unicorns will turn black to avoid being discovered by predators. Others believe that with the increase of humidity at night, the shell turns black to keep the body warm.

The technologies used in the study of unicorn biological morphology include electronic imaging scanning technology, which is a new technology used for accurate and in-depth analysis in recent years, and can help scientists establish three-dimensional images of microstructure. Mary Lasater, a researcher at Namir University, who is in charge of this research, said, "The shell structure features presented by unicorns will become an important feature of a kind of' smart material' in the future. Scientists can develop new materials as humidity detectors based on this characteristic, which can be used to monitor the humidity index of food processing plants. "

This research has been published in the Journal of New Physics published on March 1 1.
