Summary of the main content of the scarab beetle, what is the summary of the content about the scara

Summary of the main contents of the insect scarab beetle:The head of the scarab beetle is like a hat, and the body exudes a faint fragrance.

The funniest thing is that its food is animal feces! After reading the book, I realized that there were still many undigested residues in the feces of horses, cows, sheep and other animals, and the scarab beetles used these residues to slowly absorb the nutrients in them until the nutrient particles were finally digested.

Moreover, once the scarab beetle carries the dung ball into the cellar, it eats it day and night. And it is constantly excreted later.

In "Insects", the content of the scarab beetle is summarized: The Chinese scientific name of the scarab beetle is dung beetle, and they do everything for the sake of their offspring, clumsily collecting dung to make the offspring safe. praised the greatness of motherly love.

Dung beetle (qiāngláng) is commonly known as 屎shell郎 (shǐkelàng).

Insects, also known as "The World of Insects", "The Tale of Insects", "Entomological Notes" or "The Story of Insects", is a long biological work written by the French entomologist and writer Jean-Henri Casimir Fabre. The work is an insect biology work that summarizes the species, characteristics, habits and marriage habits of insects, records the real life of insects, expresses the spirituality of insects when they struggle for survival, and also records the motivation, life ambition, knowledge background, living conditions and so on of Fabre's obsession with insect research. The author integrates the colorful life of insects with his own life perception, and looks at insects with human nature, revealing the author's respect and love for life between the lines.

Dung beetles usually feed on faeces or humus and play an important role in the balance of the ecosystem. The ecological value of dung beetles includes the transfer of manure to the ground, the role of secondary seed dispersal, pollination, control of pests and intermediate hosts of parasites, as well as the development and application prospects, important biomimetic significance and major theoretical significance of Guangqi.

Dung beetles can use the phenomenon of polarization of moonlight to locate themselves to help them feed. There is a certain phototaxis. There are more than 20,000 species of dung beetles in the world, found on any continent except Antarctica.

The most famous dung beetle lives in Egypt and is 1 cm long. The largest dung beetle in the world is the 10-centimeter-long giant dung beetle. Most dung beetles are dung-eating, feeding on animal feces and have the title of "scavengers of nature".

Morphological characteristics. The whole is black and slightly shiny. The male is centimeter long, and the female is slightly smaller. The front of the head of the male is fan-shaped, with fish scale wrinkles on the surface,** and there is a large and gradually pointed upward angular process at the base and slightly square; There are compound eyes on both sides of the back, and there is a bright and wrinkle-free narrow band between the compound eyes.

The dorsal plate of the prothorax is densely covered with well-proportioned small roundoids, with a transverse ridge in the middle, the middle part of the ridge is slightly curved forward into an obtuse angle, and there is one dentate horn process at each end, and there is a shallow concave in the anterior and lower part of the odontoid, the bottom is smooth without a small round process, and there is a deep concave on the outside of the shallow concave, and the small round process at the bottom is very vague or absent; Small shields are not visible; The forewings are elytra, rather elevated, covered with dense wrinkled cuts, with 7 easily discernible longitudinal lines on all sides.

The scarab beetle is oval-shaped, also known as the dung shell, and it looks a lot like an undigested stem.

Scarab beetles live in grasslands, mountains, deserts and jungles, and wherever there is animal droppings, they will be industrious. In the vast world of beetles, the most amazing thing about scarabs is that their bodies are covered with armor that glows bronze, or faint emerald green, or dark blue.

The Insect Tale tells the story of the scarab beetle making a pear-shaped egging room, selecting high-quality ingredients, kneading it into small balls and rolling it into a hole. On the second or third day, the unformed ball of dung at the beginning has become an impeccable pear-shaped ball of dung. The mother scarab beetle knew that the plug at the back end of the scarab beetle would transmit the squeezing pressure to the embryo, so she sealed the opening with a plug that had not been patted and pressed, so that the air was smooth and the larvae were safe.
