1. Appearance: cicadas are larger plant-sucking insects, usually about five or six centimeters long. Their needle-like hollow mouths can pierce trees and suck the sap. There are also different species of cicadas, which are similar in shape but different in color. Cicadas have three less sensitive eyespots in the middle of each eye, and thin tubes that act as supports are simply distributed on each wing.

2. Characteristics: cicada larvae live in the soil, stinging and sucking sap from plant roots, weakening the tree and making the branch tips? die, affecting tree growth. Cicada larvae live in the soil all their lives. When it is about to be feathered, it drills out of the soil surface at dusk and at night, climbs to the tree, and then grasps the bark and molts and feathers. The process of molting begins when a black crack appears on the back of the cicada pupa.

The whole process takes about an hour.At the end of June, the larvae begin to feather into adults, with a maximum lifespan of about 60 to 70 days.In late July, the female adults begin to lay eggs, and in early and mid-August is the peak season for spawning, which is mostly laid in the tops of the branches that are 4 to 5 millimeters thick. In the summer in the tree screaming loudly, with a needle prick mouthparts sucking sap, larvae inhabiting the soil, sucking the sap of the roots, harmful to the trees.

3, habits: cicadas in the summer, in the tree screaming loudly, with a needle prick mouthparts sucking sap, larvae perched in the soil, sucking the sap of the roots, harmful to trees. Male cicadas have articulators on their abdomen, which can continuously emit a sharp sound. Female cicadas do not vocalize, but have a hearing apparatus in the abdomen. The larvae live in the soil and suck the roots of plants, and the adults eat the juice of plants. Cicadas belong to the class of incomplete metamorphosis, from eggs, larvae (wakame), after several molts, without passing through the chrysalis period and become adults.

Souvenirs Entomologiques, also known as The World of Insects, The Story of Insects, Entomology Notes, or The Story of Insects, is a book-length work of biology written by the French entomologist and man of letters, Jean-Henri Casimir Fabre,*** in ten volumes.The first volume was first published in 1879, and the 1907 The entire book was first published.

The work is an overview of the species, characteristics, habits and nuptial habits of insects, insect biology, records the real life of insects, expressed in the struggle for survival of insects show spirituality, but also recorded Fabre obsessed with the study of insects motivation, biographical ambitions, intellectual background, living conditions, etc.?

The author integrates the colorful life of insects with his own feelings about life, and looks at insects with human nature, revealing the author's respect and love of life in every line.

The Book of Insects is a book about the life of insects, involving more than 100 kinds of insects such as dung beetles, ants, and Sisyphus bugs. In this world, mankind now knows about one million species of insects, accounting for 5/6 of all known animal species; and there are still millions of unknown insects still waiting for mankind to discover and recognize. Fabre, in the mid-19th century, when he was not teaching at school, observed all kinds of insects in the fields with his own children, named them, and eulogized them.

The Book of Insects is divided into ten volumes, each volume is divided into chapters ranging from 17 to 25 Each chapter depicts the life of one or several kinds of insects in detail and profoundly, and at the same time, it includes a number of biographical essays that tell about the experience and reminisce about the past. In the book, the author describes the tireless efforts of tiny insects to survive and reproduce by adhering to the rules of nature.

Based on his lifelong experience and achievements in insect research, the author looks at the nature of insects in a humanized way, and reflects the social life with the nature of insects. He focuses on the external morphology and biological habits of the insects that he has observed and researched, and realistically records the instincts, habits, labor, and death of several common insects.

In addition, this book not only exhaustively records Fabre's research results, but also records the motivation for Fabre's obsession with insect research, his biographical ambitions, his intellectual background, and his living conditions, especially "Alma's Laboratory", "The Return of the Ancestor Phenomenon", "My School", "The Pond", "Mathematical Reminiscences: Newton's Binomials", "Mathematical Reminiscences: My Little Table", "Reminiscences of My Childhood", "Unforgettable A Lesson," and "Industrial Chemistry" chapters.

If you look at it differently, think of The Book of Insects as Fabre's autobiography, a very peculiar autobiography, in which the insects are nothing more than evidence of his research experience, biographical circumstantial material.
