Which insect has its own unique nature

A red-brown forest ant that lives in forests, it is a loyal guardian of forest protection and ecological balance. There are some butterfly moth pests in the animal food of forest ants: Spodoptera exigua, pine inchworm, and pine needle poison moth.

According to statistics, in a pine forest with an area of one hectare, as long as there are hundreds of thousands of forest ant colonies resting in it, it can effectively prevent pine caterpillars and other forest pests from multiplying in the woodland.

Both the bumblebee and the red-eyed egg wasp also belong to the order Hymenoptera. They differ in that the latter is much smaller in size than the former. They "get rid of pests" by laying their eggs in the larvae of pests (e.g. butterfly moths) or in the eggs of pests (as is the case with red-eyed egg wasps).

The hatched larvae grow up on the nutrients provided by the body (or egg) tissues of the pest, that is, they use "parasitism" to achieve the purpose of eliminating the pest.

Walking insects are fierce and extremely fast, and although walking insects themselves are a type of beetle, this does not prevent them from attacking harmful beetles that harm agriculture. They specialize in preying on lepidopteran larvae and are important natural enemies of pests such as armyworms.

The seven-star ladybug is also a beetle, commonly known as Sister Hua. They specialize in dealing with agricultural pests – aphids. The reason why the nickname "Sister Hua" is attached to their heads is because of the seven spots on their elytra.

The insect family has 4 5 species of all animals, about 1 million species, the team is huge, the distribution is extensive, the action is changeable, to count how many beneficial insects among them, it is indeed not easy, how many beneficial insects are still a mystery, as the insects themselves are constantly changing, people continue to make new discoveries in the study of insects, and the mystery of this mystery is constantly changing.

If you say it, you have to give points This absolutely incisive answer is cockroach Xiaoqiang wrote the myth that has not been extinguished since the Silurian period. Brother Qiang is an immortal legend.

1. Spiders will hang their webs in the air; Water striders can paddle; Cockroaches can survive nuclear **; Locusts can fly up to 80 kilometers a day; Fireflies emit light; Fleas can jump up to 150 times their height; Dung beetles can roll dung balls in a straight line at night when they can't see their fingers; Dragonflies have a 97% success rate in catching prey; Fart beetles can spray a mixture of toxic chemical solutions at temperatures up to 100 degrees Celsius; Ants can lift more than 400 times their body weight and haul objects up to 1,700 times their own weight.

2. There are many kinds of insects with different forms, belonging to arthropods in invertebrates, and they are the most numerous animal groups on the earth, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses), and their traces are almost everywhere in the world.

3. Until the beginning of the 21st century, there are more than 1 million species of insects known to mankind, but there are still many species to be discovered. Insects are the most diverse and abundant in the animal kingdom and have a significant impact on agricultural production and human health. The most common are locusts, butterflies, bees, dragonflies, flies, grasshoppers, cockroaches, etc.

Both the insect and human bodies are divided into three categories: head, thorax, and abdomen.

Common characteristics of insects:

1. The body has three sections: head, chest, and abdomen.

2. Two pairs of wings and three pairs of legs.

3. A pair of antennae are born on the head, and the bones are wrapped around the outside of the body.

4. The form of life is changeable, and it is all over the world.

5. Their bodies are not supported by an endoskeleton, and are covered with a shell made of chitin, which is segmented to facilitate movement.

The relationship between insects and human beings is complex and close, some insects have caused great disasters to human beings, and some species have brought abundant resources to human beings.

"Insects are animals, animals are mainly divided into vertebrates (mainly including fish, amphibians, reptiles, birds and mammals) and invertebrates, the latter is a lot of species, relative to the former is a primitive type of animals, mainly including single-celled protozoa (such as paramecium), coelenterates (such as jellyfish, sea stingers), flat-bodied animals (such as schistosomiasis), nematozoa (such as roundworms), annelids (such as earthworms), molluscs (such as shells, mussels)...1.

Head Antennae: A pair of antennae grow on the front of the head, and their shape varies greatly depending on the insect species. The antennae, like a human nose, are mainly used to smell smells; In addition, the antennae of some insects have the function of sensing air vibrations.

Compound eyes: A pair of compound eyes grow on both sides of the head. It is made of.

2.Thorax The thorax is where the main locomotor organs of insects are present. From the external officer, it can be divided into three segments, that is, the anterior chest, the middle chest and the posterior chest. On either side below each thoracic segment grows a pair of feet, so three.

3.Abdomen Compared with the previous two parts, the structure of the insect's abdomen is relatively simple, and there are not too many accessory structures, and the more obvious structure should be.

This is the midge, the larvae are called bloodworms, which inhabit the bottom of the water and feed on organic matter, which is an important bait for fish. Adults suck plant sap and do not bite, and although they look like mosquitoes, they are not mosquitoes.

It's not a mayfly, it's like some kind of mosquito-like insect.

This should be a mosquito, a nasty mosquito that will suck human blood in summer, and then have an allergic reaction in people, redness, swelling and itching, spreading diseases, hateful mosquitoes.

I don't know what it is, but I know that it is a lot on a sunny day, it is very disgusting, you can call the termite prevention department to help extinguish it, our unit also had a lot of it a few days ago, and the termite killer sprinkled a lot of medicine from the hole, and now there is no more. It may be termites, in short, it is very harmful, because it is very fecund, and the house or tree can be hollowed out, and it will be extinguished quickly.
