Insects and Fireflies Chapter 5

Insects remember fireflies.

The main chapter is that the firefly has six short legs, and there are colorful colors, the body is chestnut brown, the chest is red, and the edges of the ring clothing are dotted with some bright red spots. Fireflies live by sucking the meat of animals, and the most popular thing for fireflies is snail meat, and the fireflies suck the meat of the snail clean, leaving only an empty shell in it. The small lantern on the last body of the firefly is what we call the tail light, and only the male firefly has a tail light, and the female fluorescent band will not be affected even if it is disturbed or strongly frightened by the outside world during the mating period.

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 in their struggle for survival, and records Fabre.

The motivation for obsessing with insect research, life aspirations, knowledge background, life situation, etc.

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. "Insects".

It blends science and literature, which also means that it has both scientific rationality and literary sensibility. From time to time, the book is full of witty words, proposing deep reflections on the value of life, and trying to integrate deeper meanings into science.

It can be said that the perceptual tone and motivation of this work are a kind of awe and love for life, a sober understanding of survival, and a deep feeling for life. And scientific rationality can only be sustained with the support of this sensibility. In short, the information recorded in "Insects" is true and reliable, detailed and profound, and the writing is concise and clear, so it is very popular with readers.

10. Chapter 10: It reveals to people the deep affection of these insects for their lovers and children, and composes the love poems of the insect world in vivid and plain language.

The book can be divided into ten chapters:

Chapter 1: Describes the habits and instincts of scarabs, arthrophthralis mud wasps, and locust mud bees.

Chapter 2: Describes the life of the burr sand mud bee in the barren rock garden.

Chapter 5: A description of the hive built by the wasp, with geometric precision.

Chapter 6: An account of the tireless efforts of insects such as tarantulas, round-web spiders, and scorpions to survive.

Chapter 7: Introduce the marriage customs and egg laying of insects such as golden beetles, pine gill beetles, swamp iris elephants, and fireflies.

Chapter 8: Introduce the habits of insects such as fragrant tree aphids, bee aphid flies, and streamed round web spiders.

Chapter 9: Explain that humans do not exist in isolation, and that insects are an indispensable link in the earth's biological chain.

Chapter 10: Revealing the feelings of insects for their lovers and children.

The habits of fireflies in "Insects" are as follows:

Fireflies are divided into two categories: terrestrial and aquatic according to their living environment, with the former accounting for the majority. Terrestrial fireflies mostly inhabit places with high shading, lush vegetation and high relative humidity, while aquatic fireflies have higher requirements for the environment, and the water cannot be polluted or polluted by lights.

Firefly larvae are classified into aquatic and terrestrial. The larvae generally need 6 metamorphoses before entering the pupal stage. The larvae eat snails and crustaceans, and after catching prey, they will first anesthetize and inject digestive juices into their bodies to break down the meat.

In the grass, it is common to find terrestrial firefly larvae with two points of light on the tail, and two-color weeping firefly larvae with black and white glow all over the body, and the wings of the growing females of these two species are degraded and not much different from the shape of the larvae, so that the male can fly.

The principle of luminescence of fireflies.

Fireflies can emit light, mainly because it has specialized light-emitting cells, and there are two substances in the light-emitting cells, one is luciferin and the other is luciferase. Luciferin can consume ATP under the catalysis of luciferase and react directly with oxygen, producing an excited state of luciferin oxide, which releases photons when it returns from the excited state to the ground state. That's why fireflies can emit light.

First of all, the author Fabre introduced how fireflies emit light, Fabre caught a firefly home, observed the light-emitting organs of fireflies under the microscope, and found that there was a fine-grained white substance on the ** of fireflies, and the fluorescence was emitted from here.

Fabre then explains how fireflies hunt. Can you think of what fireflies eat? It turned out to be a behemoth - Snail Zen Dan Niu Bi rent!

It first waited quietly next to the snail, once it saw the snail's body sticking out of the shell, it hurriedly flew over quietly, and pierced the snail's body with a poisonous needle on its leg.

In The Insects, Fabre studies the fireflies in detail through the following observations:

1.Experimental method: When Fabre observed the fireflies, he observed the principle of their luminescence and the way they emit light through experiments.

2.Observation: Fabre conducted a microscopic observation of the luminous parts of the fireflies, revealing the mechanism of the fireflies' luminescence.

3.Description: Fabre used detailed text to describe the luminous part of the firefly, the luminescence principle and the luminescence method, so that the reader can understand the luminescence phenomenon of the firefly more intuitively.

4.Comparative Method: Fabre also compared different species of fireflies and found similarities and differences in their luminescence principles and luminescence methods, so as to better understand the luminescence characteristics of fireflies.

Through a swift observational approach, Fabre reveals the mechanism by which fireflies emit light, showing the reader how these small insects use their biological properties to emit light.
