What do insect boxes have in common and what are the differences?

Insects generally have the following characteristics:

1) The body is clearly divided into three parts: head, chest, and abdomen, and each part is composed of several links. The head is formed by the healing of 6 links, and there are no traces of knots in the adult body. The thorax is composed of three segments: anterior, mid, and posterior thorax.

The abdomen consists of 3 12 segments, most of which are 10 11 segments.

2) Adults have three pairs of segmented feet, each on which they grow on three thoracic segments. (Animals with fewer than three pairs or more than three pairs of legs are not insects, which is the most obvious sign of identifying an insect.) ）

3) Most adults have two pairs of wings on their chests, some species of insects have evolved to have only one pair of wings (e.g., mosquitoes, flies), and some species of insects have completely degenerated wings (e.g., fleas, lice).

4) Insects have a pair of segmented antennae on their heads, which have the sense of touch and smell, and are used for pathfinding, feeding, direction identification, and courtship.

5) Insects do not have bones in their bodies, and adults have a shell on their body surface, called "exoskeletons".

What insects have in common is that they all have three pairs of legs and two pairs of wings. Insects are of great variety and morphology, belonging to the arthropods of invertebrates, and are the most abundant animal group on the planet, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses), and their traces are found in almost every corner of the world. Until the beginning of the 21st century, there were more than 1 million species of insects known to humans, but there are still many species yet 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.

Insects: The body of insects is divided into three parts: head, thorax, and abdomen. Adults usually have 2 pairs of wings and 6 legs, the wings and feet are located in the thorax, and the body is composed of a series of body segments, which are further assembled into 3 segments (head, thorax and abdomen).

A pair of antennae are head-born, and the bones are wrapped around the body; The form of life is varied, and it is spread all over the world. It is one of the most diverse arthropods. Insects are the most abundant animals in the world, with more than 1 million species discovered, more than all other animal species combined.

Insects are structurally different from vertebrates in that their bodies are not supported by an endoskeleton and are covered with chitin.

chitin). This shell is divided into sections to facilitate movement, like a knight's armor. Insects play an important role in the biosphere.

Insect flowers need the help of insects in order to spread pollen. And honey collected by bees is also one of people's favorite foods. In some parts of Africa, Southeast Asia, and South America, insects themselves are the food of the natives.

Different insects vary very, very differently, such as praying mantis, locusts can reach six or seven centimeters long, aphids, whiteflies are only about one millimeter, and butterflies have a wingspan of more than ten centimeters.

1) They are all composed of insects;

2) all have social behavior;

Differences: 1) Bees have wings and can fly, while ants can't.

2) The empire of ants has only a division of labor, which can be considered without hierarchy. The queen ant is nothing more than an egg-laying machine in the Empire, and although it is served by other ants, it lives in the same conditions as other ants and feeds on the same type of food.

In the Empire of Bees, the hierarchical boundaries are very clear: the queen bee has enjoyed better living conditions and food (royal jelly) since she was a child; Other bees are not eligible for these benefits.

<> insects and make a lot of noise, they have three pairs of legs and two pairs of wings.

Insects come in a variety of forms.

Its basic characteristics are the body with three segments: head, chest, abdomen, two pairs of wings and three pairs of feet; 1 pair of antennae cephalic, bones wrapped around the outside of the body; The form of life is varied,

Adults are divided into three parts: head, thorax, and abdomen;

The head has a pair of mouthparts and antennae;

often monocular and compound eyes;

There are 3 pairs of feet on the thorax and no feet on the abdomen;

There is an exoskeleton with chitin on the body surface.

Adults have three pairs of legs, all in the thoracic segment The usual classification is as follows: insects are divided into two subclasses: wingless and winged. The wingless subclass contains five orders:

Protocoptera, Snaptails, Dicoceda, Tassels, and SteleopteraWinged subclasses are divided into ectophytic subptera, endopterythera and endophytic subptera, and there are 18 orders in exophytic ptera: mayflies, dragonflies, cockroaches, praying mantises, isoptera, homoptera, ptera, winged, rodids, orthoptera, cockroaches, spinopods, hemiptera, leatheroptera, tasseloptera, rodents, trichophares, liceoptera, endoptera There are 9 orders: Coleoptera, Pulsedactera, Twisteroptera, Broadptera, Lepidoptera, Snake Flyings, Dipteras, Trichooptera, Diptera, Hymenoptera.

Insect wings are different from birds' wings, but they all have these things in common in terms of their suitability for flight:

The fan-shaped structures are conducive to flight, and the operation of these structures is caused by the contraction and relaxation of the muscles, which can produce upward lift and forward power in the air.

There are many differences between plants and animals, such as plants are usually autotrophs, usually photosynthesize, usually have roots, are usually fixed in one place, usually do not move autonomously, etc.; Animals, on the other hand, are usually other tropic organisms (feeding type), usually do not photosynthesize, usually do not move constantly, and so on.

But these are all "usual", which means that there are exceptions. For example, insectivorous plants such as Venus flytrap, pitcher plant, and sundew will capture insects as nutritional supplements, and some saprophytic plants (such as crystal orchids) and parasitic plants (such as dodder seeds, mulberry parasites, etc.) do not need to photosynthesize, while the lower animal greeneye insects contain chlorophyll in their bodies, and will photosynthesize in a sunny environment to survive in an autotrophic way. Even some higher seed plants do not have a root system, such as pineapple iron orchid, hanging from branches or power lines to absorb atmospheric moisture with their stems and leaves, oysters will stay in one place for life, but mimosas will make rapid movements that are visible to the naked eye, and the fruits of sorrel, impatiens, and spray melon will suddenly collapse and pop out the seeds when they are ripe.

There is only one feature that really separates plants and animals - that is, the cell wall, all plant cells have a cell wall, while all animal cells do not have a cell wall. This is the only feature that has no exceptions, although it is quite unintuitive.

As for the similarity between plants and animals, it is that they are both living beings and both grow and reproduce.

There are no similarities and differences between slaves and animals.

There is an exoskeleton on the surface of the body, the body and appendages are segmented, there are three pairs of legs and two pairs of wings, and breathe through the trachea.

The body is divided into three parts: head, thorax, and abdomen The head has a pair of antennae, a pair of compound eyes, and a mouthorgan The thorax has 3 pairs of legs, and generally has 2 pairs of wings.

Insects belong to the category of arthropods. All arthropods have a hard body shell or exoskeleton for protection. The exoskeleton that covers the entire body is made up of separate body segments with flexible joints connected to each other.

The muscles of arthropods are attached to the inside of the exoskeleton, and they move their bodies by pulling apart the somites.

The first is small, and the second is more!

The body surface has an exoskeleton, the body is segmented (one segment at a time), and most insects have 3 pairs of legs and 2 pairs of wings.

It is composed of three parts: head, thorax and abdomen, with antennae, 3 pairs of legs, exoskeleton, and oval larvae and adults.

Adults are divided into three parts: head, thorax, and abdomen;

The head has a pair of mouthparts and antennae;

often monocular and compound eyes;

There are 3 pairs of feet on the thorax and no feet on the abdomen;

There is an exoskeleton with chitin on the body surface.
