What do the biological characteristics of insects mainly say?

The characteristics of insects, the biological characteristics of insects, take you to understand insects intuitively.

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.

Common insects are butterflies, bees, grasshoppers, moths, caterpillars, beetles, flies, mosquitoes, chi, praying mantises, dragonflies, fireflies, snails, caterpillars, earthworms, mosquitoes, flies, cockroaches, ants, locusts, clans, grasshoppers, pupa, silkworms, cicadas, centipedes, bed bugs.

Folk common name. Stinky Sister: The scientific name is Tsubaki. She can fly, about the size of a fingernail, covered in black and gray, only a little pink under her wings, there is an incomparably foul smell, and it can't be washed off when it sticks to her hands for a long time. She has this self-defense skill, which is enough to make bad intentions shy away.

Yanglazi: Stinging moth, camouflage, light green and half a green jujube, soft and like a turtle, with fine fluff all over the body, once stuck to the hand, it is red, swollen and itchy.

Knife mantis: that is, the praying mantis, if you find a knife mantis in the grass, it often stands up and raises its arms with barbed teeth, and sways slightly back and forth to demonstrate to you, which is the standard posture of praying mantis boxing.

Quack: that is, a short-fronted negative locust, green in color, and slender in body. In some places, it is also called "bye-bye jump" or "flat hook".

Insects include dried mud wasps, fireflies, and crickets.

Grasshoppers, scarabs.

Wait a minute. 1. Dried mud wasps.

Prefer to build their nests in moist and warm places, often build their nests in chimneys, where the temperature is suitable for the dry mud wasp to survive, but the young of the dry mud wasp often suffocate, so the dry mud bee will build its nest in the wide chimney.

2. Fireflies.

Outwardly, it has six short legs and likes to walk. When the male firefly is fully developed, it will grow wings, and because it is a beetle itself, the female firefly will be in a larval state for the rest of its life.

3. Crickets. When choosing a place to live, a naturally formed hidden place is not chosen because these holes are not suitable. It was all built in a hurry and without security. Usually choose places with good drainage and plenty of sunshine, and when choosing these places, you have to build them yourself.

4. Grasshoppers. Strong feet, big belly and good jumping. Found in wild grasses, low forests, and shrubs, often hiding in grass, or crawling, perching, and foraging on plant stems. It mainly eats the stems, leaves, melons, and fruits of plants.

5. Scarabs.

Also known as scarab.

It is one of the largest and most well-known dung dung dung eaters. There are six fine-pointed teeth in front of the crescent-shaped parietal shell, which are not only digging tools and cutting tools, but also nutrient-free plant fibers in inserting, lifting, throwing and throwing manure materials.

can also be used as a rake, bringing all the delicious things over.

The Insect Book records dung beetles in total.

Ants, Sisyphus.

There are more than 100 kinds of insects such as insects. The book is divided into 10 volumes, each volume of 17-25 chapters, each chapter describes the life of one or several insects in detail and profoundly, and includes some biographical essays that tell about experiences and reminiscences of the past.

Insects have a wide variety of species and morphology, and they are invertebrates.

in arthropods.

It is the most abundant group of animals on the planet, in all biological species (including bacteria, fungi.

viruses) account for more than 50%, and their traces are found in almost every corner of the world.

Characteristics: Not only are there many species of insects, but the number of individuals of the same species is also very staggering. The distribution of insects is so wide that no other class of animals can compare with it, and it is almost all over the earth.

There are different types. Most insects can be used as specimens, and they are a good biological resource that humans can use.

Insecta range:

There are about 1 million species of insects in the world, some estimate 2 million species, and about 10,000 new species are discovered every year. There are about 12,150,000 species in China. There are many species of insects (about 80% of the species in the animal kingdom), with different habits and a wide range of distribution, except in the waters of the ocean, insects can be found in all areas where plants grow.

Insects have a strong ability to fly, and their tiny bodies are easy to spread with air currents, so they can be found from the equator to the poles. For example, butterflies have been found at 80°N, and mosquitoes have been found at 70°N; Insects have also been found in the Antarctic Circle.

Hemiptera has been found in the mountains at an altitude of 5,029 meters.

Insects, lepidopteran insects have been found in the mountains at 488 meters, and several wingless subclasses tend to live at higher altitudes. The upper limit of the distribution of insects is 6,800 meters above sea level. There are also insects in hot springs and caves.
