1. Knowledge about insects
1. Insects belong to the phylum Arthropods among invertebrates. The body is divided into three sections: head, chest and abdomen, usually two pairs of wings, three pairs of legs, and a pair of antennae on the head. Insecta is the largest class in the animal kingdom. The largest order in the class Insecta is Coleoptera. Insects are incredibly diverse and abundant. There are estimated to be more than 4 million species, and a single ant colony can contain up to 500,000 individuals.
2. Most insects go through egg, larvae, pupa, and adult, such as butterflies, cicadas, etc., which are complete metamorphosis; those that go through three stages of egg, nymph, and adult are incomplete metamorphosis, such as aphids.
3. Insects breathe through the trachea and valve. There is a row of neatly arranged circular holes on both sides of the insect's thorax and abdomen, which are the valves. One of the reasons why insects are highly adapted to the terrestrial environment is their special respiratory system. Insects in aquatic environments are also born with tracheal gills.
4. Pests and beneficial insects are actually determined by people. Those that are beneficial to human production are called beneficial insects, while those that destroy production and hinder life are pests. Some insects can help pollinate entomophilous flowers.

That's a midge: commonly known as "little bite" and "black mosquito", it is the smallest blood-sucking insect in the order Diptera.
There are about 4,000 species of this insect in the world, many of which suck the blood of humans and other warm-blooded animals. Midges are only about 1 mm long, making it difficult to see them clearly.
What makes them even more hateful than mosquitoes is not only their small size, lack of mosquito-like sounds, and strong stealth, but also they always attack humans in groups. When people encounter small bites, unless you wear a veil over your head and tighten your sleeves and trouser corners, they will always bite you until your whole body becomes red and swollen, making you extremely uncomfortable.
Midges live in moist places such as seaside, rivers, lakes and swamps. They are usually active in the early morning or dusk when there is no wind or rain. When the sun is high, they hide.
Small bites can not only cause skin redness, swelling and itching, but can also lead to infection in severe cases. At the same time, they may also transmit viruses while sucking blood, causing illness in humans and other animals.

1. Caddis: It is the larvae of Caddisia.
They cling to the broken branches of reeds and drift with the water. The small sheaths formed by these broken branches are their houses. Sometimes, caddis flies will use very small shells to piece together a house; sometimes, they will use rice grains to pile up the house and decorate it like an ivory tower. This is their luxurious residence.
The caddis house is their top-secret defense tool, a small sheath, or the caddis' "submarine". 2. The ball-pushing dung beetle (commonly known as the "dung beetle"): It is an ancient animal. In the past, farmers in ancient Egypt saw a dung beetle pushing a ball-like object and thought it was a model of the earth. They believed that this beetle had Astronomical knowledge calls it the "sacred beetle".
Fabre revealed the mystery of "the dung beetle pushes the ball".
It turns out that dung beetles like to eat dung balls.
One of its important daily tasks is to roll the feces into a ball and push it home. The ball is made of food carts and storage rooms, rolled up with garbage. During the transportation, they will get pretended help from their companions, but in fact, they are uncooperative insects, and their companions will snatch and steal their companions' food.
3. Singing cicada: The larvae live in underground tunnels. After living underground for 4 years, the larvae crawl to the ground and turn into cicadas. The adults live in trees, drilling through the silky bark with their pointed awl-like mouths, inserting their straw-like mouths into the holes to drink the tree's sap.
