After reading the "My Diary Series" (such as "The Diary of a Watermelon Worm", "The Diary of a Butterfly", "The Diary of a Ladybug", "The Diary of a Dragonfly") picture books, I feel that these little bugs are really Q!
June 8
My name is Watermelon Worm, but I am neither a watermelon nor a worm.
Because insects have only 6 feet, I have: 1, 2, 3, 4, 5, 6, 7, 7 on one side and 7 on the other.
In addition to the feet, the front of my body, there is a pair of tentacles.

Others will never understand that when a little ladybug is, there is some distress.
I think, like a little dragonfly, with a slim body...
I think, like a little butterfly, with big and beautiful wings...
I thought, like a little bee, put on a striped skirt...
—— Excerpt from "The Ladybird's Diary"
After that, the blind editor, who did not even recognize the praying mantis, began to be particularly interested in insects. After understanding that insects are the largest proportion of biological groups in nature, Xiaobian feels that it is necessary to know and understand these insects.
According to the study, except for the seafloor, there are insects in all known environments. There are insects everywhere in our lives, from hateful cockroaches, nasty flies and mosquitoes, to industrious bees, beautiful butterflies and dragonflies, and there are many insects hidden around us, but they are not easy for us to find.
It is particularly coincidental that I recently saw a super interesting insect science book - "Plants vs. Zombies 2 Weapon Secrets: You Ask Me answers science comics and insect volumes". After reading the whole book, I can't help but want to share a few interesting facts with you. Xiaobian's desire to share, you know, because our goal is to choose a good book for children and increase knowledge with everyone!
Some questions Xiaobian has never thought about, but some of them, the children of relatives have asked Xiaobian, and the xiaobian who was embarrassed is not embarrassed. For example, they are curious (dear readers and friends, you can think about these questions first, and later xiaobian will reveal the answers for you):
1. What color is the blood of insects? (The editor looked confused: Ah, isn't the blood all red?) Wait, do insects have blood? ）
2. Why do dragonflies need water? (Xiaobian weakly guessed: This, it should be the dragonfly thirsty.) ）
3. Why do fireflies glow? (Xiaobian strong self-composure: the night is too dark, there is no bright light fireflies will get lost.) ）
……
Dangdang, the answer is revealed immediately!
1. What color is the blood of insects?
The blood of humans and animals is generally red, and the blood color of insects is much richer in comparison. The blood of insects is composed of plasma and blood cells, and the blood color is divided into amber, yellow, orange-red, blood red, blue-green and green, which are similar to colorless.
So why is that? It turns out that the pigments contained in the blood of insects give their blood a specific color, and these pigments are usually obtained from food. Different species of insects eat different foods, and the pigments obtained from them are naturally different.
2. Why do dragonflies need water?
Speaking of dragonflies, xiaobian always has in mind the beauty of "the little lotus only shows its sharp horns, and there are dragonflies standing on the head", so it is speculated that the dragonflies standing on the lotus leaves must be thirsty before they light the water from time to time, and the posture is beautiful and light.
However, the goose, the truth is: dragonflies do water to reproduce, because the fertilized eggs of dragonflies can only hatch in water. Fertilized eggs that are discharged into the water are usually attached to aquatic weeds and then hatch a larvae, the water ant (chài). After living in the water for a period of time, the water lice will crawl out of the water along the branches of aquatic plants and become adult insects that spread their wings and fly - dragonflies.
3. Why do fireflies glow?
Fireflies are bright memories of childhood summer, watching them flash in the dark, when I was a child, I thought it was them walking at night with lanterns.
In fact, fireflies emit light because they have a light emitter at the end of their abdomen, and the light emitter is composed of several layers of cells, including light emitting cells and reflective cells. Luminescent cells contain luciferin and luciferase. When active, fireflies inhale oxygen, which enters the light-emitting cells through small trachea, causing fluorescein to interact with luciferase, causing the glowworm's abdomen to glow.
This is a kind of cold light, also called fluorescence. It turned out that this flickering fluorescence was a tool for fireflies to communicate, like the dance of bees.
4. What insects do their tailoring work?
What？ Are there insects that do tailoring work? Could it be a spider? But they just weave nets, don't they? - Oops, spiders are not insects. (As for why it doesn't belong, I won't list it here, so let's go to the book and find the answer.) ）
Back to the main topic, there is a tropical ant called the tailor ant. They nest in a very peculiar way, in which the leaves of the plant are gathered together and then the two leaves are glued together with sticky ant silk, just like sewing two pieces of cloth together with needle and thread. The silk is made of the larvae of the tailor ant, and each worker ant crawls back and forth between the two leaves with the larvae, leaving a complete silk thread on it, thus sticking the leaves and making a small nest.
