What kind of insect is an insect? Which bugs are insects?

Insects are invertebrates and belong to a class of the phylum Arthropods among invertebrates, called Insecta.

Insectidae all have some common characteristics, the main ones are:

The body of the adult worm is divided into three parts: head, thorax, and abdomen. The head has a pair of antennae, a pair of compound eyes and several monoculars, and a different form of mouthparts. The thorax has three pairs of legs and two pairs of wings (or one pair of wings, few without wings).

The abdomen is divided into multiple segments, generally without appendages, and each segment has a stomata on each side, which is the respiratory organ of insects. There is a chitinous exoskeleton on the surface of the body and no bones in the body.

The body is divided into three parts, a pair of antennae, a pair of compound eyes, three pairs of legs, and two pairs of wings, which are the most obvious features of insects.

Common insects are: flies, mosquitoes, dragonflies, locusts, praying mantises, cockroaches, bees, butterflies, moths, stick insects, beetles, aphids, cicadas, ......

Insects According to the characteristics of insects, spiders, scorpions, centipedes, shrimps, etc., are not insects.

Common insects are butterflies, bees, grasshoppers, moths, caterpillars, beetles, flies, mosquitoes, chi, praying mantises, dragonflies, fireflies, snails, caterpillars, earthworms, mosquitoes, flies, cockroaches, ants, locusts, feces, grasshoppers, pupa, silkworms, cicadas, centipedes, bed bugs, beetles, ladybugs, fleas, lice, e, crickets, termites, scorpions, spiders, grasshoppers, mealworms, crickets.

Butterfly: One of the disseminators of pollen from a variety of plants, the butterfly is a bee turned from a caterpillar: a symbol of industriousness, striving to collect honey.

Praying mantis: Feeds on grasshoppers and other small insects.

Moths: can fly, often hear moths fighting fires, other information does not know caterpillars: the previous life of butterflies, caterpillars are mostly hated by people, because it is uncomfortable to see ants:

Carrying garbage in the place, you know the work all day long, ants gnaw bones and are divided into grades, and different levels of ants take on different jobs.

Beetle: Seven-star ladybug knows.

Flies: Turned from maggots.

Mosquitoes: Drink our blood every day in the summer.

Locusts eat their adults or larvae, and all kinds of locusts, including grasshoppers, can eat them. Beat the locusts with leafy branches, or spread a plastic film on the ground to drive the locusts onto the film, because the film is smooth and the locusts cannot escape and are easy to catch.

The trunk is roughly divided into the head, thorax and abdomenThree parts, there isTwo pairs of wings, there isThree pairs of feet (three pairs!) Three pairs! Three pairs!

Six of a kind! ）, there isExoskeletonYes, yesHulling, it's an insect.

For example: locusts, bees, praying mantises, cicadas, cockroaches.

Attached are a few examples that are not insects: spiders (there areFour pairs of legs, belonging to arthropods).

Centipedes (supernumerous, superple, also arthropods).

We usually think that all bugs are insects, but in fact, this idea is wrong.

To find out whether a bug is an insect, it is necessary to identify it from the characteristics of its body. The body of all insects is divided into three parts: head, thorax, and abdomen, and there are three pairs of legs on the chest, which is the main feature of insects. Spiders and centipedes are not insects because the body of the spider is divided into only two parts and has 4 pairs of legs; The centipede's body is divided into a head and torso, and there are many uncountable feet, and it is certainly not an insect.

Most adult insects have a pair of antennae on their heads, which have the functions of touch, taste and smell, such as the tentacles of butterflies and parasitic wasps can sense tastes, the tentacles of male mosquitoes can sense sounds, and ants and bees can express meaning to each other when they touch their tentacles. The tentacles of different species of insects have different roles and functions.

In addition to one eye, the insect has one pair of compound eyes on its head.

Except for a few insects that do not have wings, most insects have two pairs of wings. In general, the front wings of the beetle become hard and cannot be used for flight, but can only be used to protect the hind wings and abdomen. There are also insects whose hind wings have degenerated, leaving only the forewings, like mosquitoes and flies.

The wings of different insects grow differently, the wings of dragonflies are transparent, and the wings of moths and butterflies are covered with patterned scales.

When summer arrives, you can expect to see critters flying, biting, and escaping in warm weather. But whether you tolerate these creepy reptiles or are glad never to see them again, you're probably asking yourself: which ones are bugs and which ones are insects?

Bugs and insects don't have to be the same thing. The two terms are used interchangeably, with insects appearing primarily in scientific contexts, while insects are used more casually, but the difference between terms is not just semantic. They all describe groups in the scientifically recognized animal kingdom.

The boundaries around insects are clearer than those around bugs. Insects are a category within the phylum Arthropods, which also includes arachnids such as spiders, myriapods such as centipedes, and crustaceans such as crayfish. Insects, as well as all arthropods, have segmented legs and a hard outer layer called an exoskeleton.

Unlike some other arthropods, insects typically have 6 legs, 2 antennae, and a body that is divided into three parts (head, thorax, and abdomen). Insects contain many organisms that you tend to think of as bugs. Ants, grasshoppers, bees, and flies are all insects.

All bugs are insects, but not all insects are bugs by the technical definition. True bugs belong to a type of insect called Hemiptera. There are a few characteristics that distinguish bugs from other insects:

Most bugs have a straw-like mouth or stylet that they use to squeeze sap from plants or blood from animals. They also tend to have long, segmented antennae and wings that are hard and black where they come into contact with their body, with thin and translucent ends. True bugs include bed bugs, bed bugs, water striders, and cicadas.

Confusingly, some insects with bugs in their names aren't actually real bugs, like ladybugs and Junebugs (both of which are beetles).

From a linguistic point of view, the line between bugs and insects becomes blurred. Most people think of bugs as any small non-sea creature with more than four legs, covering everything from spiders to beetles to millipedes. This is why entomologists refer to the members of the order Hemiptera as real bugs and not just bugs, because even they feel guilty about using the term in a general way.

Insects are the largest group in the animal kingdom. Scientists estimate that there are more than 1 million species of insects on Earth, living in every conceivable environment, from volcanoes to glaciers.

Insects help us by pollinating our food crops, breaking down organic matter, giving researchers clues to cancer**, and even solving crimes. They can also harm us by spreading disease and destroying plants and structures.

Insects are arthropods in invertebrates, are the world's most diverse animal groups, the body is divided into three parts: head, chest and abdomen, most insects are animals with three pairs of legs, often only exoskeleton, no endoskeleton, the most common are cockroaches, bees, locusts, etc.

Arthropods belong to the invertebrate group and are the most abundant group of animals on the planet.

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 one of the most abundant animal groups in the world, with more than 1 million species discovered. Hope.

The definition of insects is: arthropods, the body is divided into three parts: head, thorax and abdomen, and animals with three pairs of legs are called insects. Insects are of great variety and morphology, and belong to the arthropods of invertebrates, which are the most abundant animal groups on the planet.

The number of insects accounts for more than 50% of all biological species, and their traces are found in almost every corner of the world, and there are about 1 million species of insects known to mankind.

Insects are the most abundant species in the animal kingdom, the largest number of kinds, the distribution is wide, there is no sail early other class of animals can be compared with it, most of the insects can be used as specimens.

Insects play an important role in the biosphere and are a good biological resource that can be used by humans, but they also have a significant impact on agricultural production and human health.

Insects include butterflies, bees, beetles, caterpillars, moths, flies, mosquitoes, etc., among which butterflies have a wide variety of colors, bright colors, body slippery rent disadvantages or patterns on the wings, bees belong to the class of insects, with queen bees, male peaks, worker bees and other individuals, and beetles are insects with hard shells, such as beetles, beetles, etc.

1. Butterflies

Butterflies are insects, there are many kinds of butterflies, there are more than 14,000 species in the world, and more than 1,200 species in China, the appearance of butterflies is beautiful, the colors of the wings are rich, and the body and wings of some butterflies also have a variety of colored markings.

2. Bees

Bees are insectaceous animals, bees belong to social insects, with queen bees, male peaks, worker bees and other individuals, of which the queen bee is responsible for laying eggs, can produce 800-1300 eggs a day, male peak is responsible for mating with the queen bee, and worker bees need to be responsible for nectar collection, water, pollen and nest door protection.

3. Beetles

Beetle is a general term for Coleopteran insects, which refers to insects with a hard shell on the outside of the body, thick and hard forewings with, and membranous wings after the Shin family, such as beetles, longhorns, weevils, etc., the body size of beetles is different, the smallest is less than 1 cm, and the largest is more than 20 cm.
