First, the residence and eggs of crickets
Crickets are well-known insects. It lives on the grass, and its singing and residence are quite distinctive. La Fontaine, the fable master, once described and praised it in poetry. Another fable writer once said in a cricket voice, "How I like my secluded place! To live a happy life, hide here! "
I once saw crickets rolling their tentacles at the mouth of the cave, with their bellies facing the shade and their backs facing the sun ... Crickets' caves are usually dug in the grass on the slope of the morning sun. The advantage of this is that the rain outside the cave can flow off the slope quickly without pouring directly into the cave. The passage of the cave is about one finger wide and the whole depth is at most nine inches.
its direction is sometimes tortuous and sometimes straight, so as to adapt to the change of terrain as much as possible. There is a bunch of grass at the mouth of the cricket's cave, which is to protect the cave from rain and to hide the hole to protect the whole cave. Whenever it is quiet around, they will play in the grass at the mouth of the cave.
The cricket's cave is not luxurious, but it is not rough. At the end of the cave passage is the bedroom, which is the most spacious and smooth by comparison. The whole cave looks very simple, clean and hygienic. The cricket cherishes the house it has worked so hard to build. It doesn't move in spring or winter.
only crickets have a fixed residence among insects and enjoy a peaceful and peaceful life alone. Crickets generally choose a place with a clean environment and a sunny direction as their residence.
Second, the singing of crickets
In front of me, I introduced the cricket's residence and its spawning. Here, let's talk about the singing and mating of crickets. Like other insects, crickets can sing. Crickets sing with simple instruments, including racks, bows and vibrating membranes.
Different from other insects, the cricket is right-handed, and its right coleoptera almost covers its left coleoptera. However, its two coleopters have exactly the same structure. Both coleopters have a wide transparent dry film, which is as thin as white onion skin and can vibrate, and it is the place where crickets occur.
there are two veins in the middle of the sheath wing. There is a depression between the two wing veins, and there are five or six black wrinkles in the gap. These wrinkles constitute friction arteries, which create conditions for vibration. One of the two wing veins is the bow. It has about 15 serrations, all of which are triangular columns. Even better, it knows cadence and adjusts the intensity of its voice as needed.
can crickets sing when their musical instruments are upside down? The result of my experiment proves that the answer is yes. But I still don't stop there. I'm going to find the cricket larva and pay attention to the moment when it molts and deforms. At this time, I saw its wings and sphinxes like a tiny wrinkled sheet. One day in early May, I finally saw it shed its skin. It threw away its shabby coarse clothes.
except the pure white of the coleoptera and its wings, its other parts are chestnut red. When the cricket just came out of its coat, its wings and coleopters were small, wrinkled and incomplete. But then the sheath wings will grow up slowly. Later, I found that the edges of the two coleopters met, and the right one was about to cover the coleopters.
at this time, I used a grass to gently change the overlapping order of the coleoptera, and put the left coleoptera on the side of the right coleoptera, and it succeeded, even though it sometimes didn't fit well.
At about 3 pm that day, the cricket changed from reddish to black, so the coleoptera of this cricket grew up and matured under my intervention. Soon it began to play with this bow that its family members had never used. And its tone and rhythm are normal.
This article is from the expanded materials of Entomology by Jean-Henri casimir Fabres.
Writing background:
Entomology is a book about insect life, involving more than 1 species of insects such as dung beetles, ants and sisyphus worms. In this world, there are about 1 million known insect species, accounting for 5/6 of all known animal species; And there are still millions of unknown insects still to be discovered and recognized by human beings.
in the mid-19th century, after teaching in school, Fabres observed all kinds of insects in the fields with his children, named them and eulogized them.
at the age of 31, Fabres received a doctor's degree in natural science. During this period, he has successively created a series of biological works such as Plants and Uncle Paul's Talk on Pests.
in p>1854, Fabres published his observation of the Arthropoda in the French Yearbook of Natural Science. Three years later, he published his research results on the metamorphosis of Coleoptera, which impressed his peers with its fine academic quality and great theoretical significance. In 1879, the first volume of Entomology, which he compiled for more than 2 years, finally came out.
in p>188, Fabres bought an old house with the money he had saved, and he used the local Provencal language to give this house an nickname-Waste Stone Garden. Year after year, Fabres wore a farmer's woolen coat, with a sharp pick and a flat shovel to dig and dig, and a paradise of insects was built. He wrote the fruits of his labor into volume after volume of Insects. It was not until 197 that the tenth volume of Insects came out.
About the author:
Jean-Henri Casimir Fabre (1823-1915) was a French entomologist and writer. Known by the world as "Homer in the insect world" and "Virgil" in the insect world.
He painted more than 7 pictures of fungi in watercolors, which were deeply appreciated and loved by Provencal poet mistral. He also contributed to the bleaching and dyeing industry, and won three patents on alizarin.
