Are insects animals? Are insects animals

Yes, arthropods.

Not only are there many species of insects, but there are also many individuals of the same species, some of which are surprisingly large. An ant colony can have up to 500,000 individuals. A tree can contain up to 100,000 individual aphids.

In forests, there can be 100,000 springtail insects per square meter. When locusts occur in large numbers, the number of individuals can reach as much as 71.2 billion, the total weight is about 1,250,300 tons, and the area covered by swarms can reach 500,1,200 hectares.

Insects are animals. 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.

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.

Not only are there many species of insects, but the number of individuals of the same species is also 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.

The body of an insect 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 animals, which belong to the arthropod phylum of the animal kingdom, insects, its species are rich and diverse, the forms are different, it is the largest number of animal groups on the earth, and the morphological characteristics of insects are a pair of antennae, two pairs of wings and three pairs of feet, note that the abdomen of insects has important organs, in addition to common insects are crickets, locusts, butterflies, ants, etc.

Insects are animals, which belong to the phylum Arthropods of the animal kingdom, insects, and organisms, which are rich and diverse, with different forms, and are the most numerous animal groups on the earth, and insects are widely distributed, almost all over every corner of the world.

The morphological characteristics of insects are a pair of antennae, two pairs of wings and three pairs of legs, and the head of the insect is mostly composed of body segments, the outer wall of the skull is hard, there is a pair of antennae above the head, and the lower part is the mouthpart, and the chest is divided into three parts: anterior thorax, middle thorax and hind thorax, in addition to the abdomen of the insect has important organs.

There are more than one million kinds of insects, the more common ones are crickets, locusts, butterflies, ants, bees, etc., among which the appearance of butterflies is gorgeous, and it has a very high ornamental value when flying, ants belong to insects with high social nature, and their internal division of labor is clear, and bees can help plants teach pollen.

Spiders, bats, geckos, centipedes, frogs, earthworms, not insects. The adult of an insect always has six legs and always has three segments in the body. Usually has wings and usually antennae.

Bats are mammals; Geckos are reptiles; Centipedes belong to the class Myriapoda; Spiders belong to the class Arachniformes; Earthworms belong to the phylum Annelids; Frogs are amphibians.

Centipede: Myriapoda of the phylum Arthropod.

Spiders: Arachnids of the phylum Arthropods.

Bats: Mammals of the phylum Vertebrates.

Frogs: Amphibians of the phylum Vertebrates.

Earthworms: Annelids.

Gecko: Reptiles of the phylum Vertebrates.

The rest belong to the class Insecta of the phylum Arthropod, that is, insects.

In addition to frogs, bats, earthworms, ants, and geckos, these animals belong to the class of insects.

Animals include insects, and animals include vertebrates and invertebrates, which are divided according to the presence or absence of a vertebral column. Vertebrates include fish, amphibians, reptiles, birds, mammals. The classification of invertebrates is more complex, such as annelids, coelenterates and so on, a total of eight categories.

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.

<>1. Insects are an animal, the most numerous animal group on the planet, and arthropods among invertebrates. Insecta is not only the largest class of the phylum Arthropods, but also the largest class in the animal kingdom.

2. The body of an insect is divided into a 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 somites that are further assembled into 3 segments (head, thorax and abdomen). A pair of antennae are born on the head, and the bones are wrapped around the body; It is one of the most diverse and diverse arthropods.

3. Insects are the most prosperous animals in the world, with more than 1 million species discovered, more than all other animal species combined. The structure of insects is different from that of vertebrates. Their bodies are not supported by an endoskeleton and are covered by a shell made of chitin, which is segmented for easy movement.

4. But insects can also pose a threat to humans, such as locusts and termites. And some insects, such as mosquitoes, are transmitters of diseases. Some insects can harm humans through venom or bites. For example, a wasp injects an intruder with a stinging needle with zen trapping venom.
