How are insects different from other animals?

Insects are a type of animal that belongs to the arthropods among invertebrates.

Animals: Animals are a large group of multicellular eukaryotic lifeforms, as well as some single-celled organisms, called the kingdom Animalia. Animals are a large group in the biological world, generally can not synthesize inorganic matter into organic matter, can only feed on organic matter (plants, animals or microorganisms), so they have different morphological structures and physiological functions from plants, in order to carry out life activities such as feeding, digestion, absorption, respiration, circulation, excretion, feeling, movement and reproduction.

Insects: 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 mankind, but there are still many species yet to be discovered.

Insects are the most abundant group of arthropods, and the most common are locusts, butterflies, bees, dragonflies, flies, and grasshoppers. Cockroach. Wait.

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.

When summer arrives, you can expect to see all sorts of critters that take advantage of the warm weather to fly, bite and scurry. But whether you're tolerant of these creepy little reptiles, or you're happy to never see them again, you're probably asking yourself: Which ones are bugs and which ones are insects?

Difference Between Bug and Insect

Bugs and insects don't necessarily refer to the same thing. While the two terms are used interchangeably, and insects are mostly found in scientific contexts, while insects are used casually, the difference between the two terms is not just in semantics. They both describe groups in the animal kingdom that are recognized by science.

Insects are more clearly defined than insects. Insectans are a class in the phylum Arthropods, which also includes arachnids like spiders, myriapods like centipedes, and crustaceans like crayfish. Insects, like all arthropods, possess segmented legs and a hard outer layer called an exoskeleton.

Unlike some other arthropods, insects typically have six legs, two antennae, and a body divided into three parts (head, thorax, and abdomen). Insects contain many organisms that you think are bugs. For example, ants, grasshoppers, bees, and flies are all insects.

Although all insects are insects, not all insects are insects by definition. True bugs belong to a class of insects called Hemiptera. There are a few characteristics that distinguish bugs from other insects:

Most bugs have a straw-like mouth that they use to draw sap from plants or blood from animals.

In addition, they tend to have long, segmented antennae and have wings that are tough and dark close to the body and thin and transparent at the tail. The real bugs include stinkbugs, bed bugs, water striders, and chiro. Confusingly, some insects with the word bug in their name aren't actually real bugs, such as ladybugs and June bugs (both of which are beetles).

From a linguistic point of view, the line between bugs and insects becomes blurred. Most people think of any small non-sea creature with more than four legs as a bug, and it ranges from spiders to beetles to millipedes. That's why entomologists would refer to Hemiptera members as real bugs and not just bugs :

Because even they themselves misuse the term in the usual way.

Insects are animals and are a type of 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 constructed differently from vertebrates in that their bodies are not supported by an endoskeleton and are covered with a shell made of chitin. This shell is divided into sections to facilitate movement, like a knight's armor.

The main features that distinguish insects are as follows:

1.The body is clearly divided into 3 parts: head, chest, and abdomen.

2.The head is segmented, with mouthparts and 1 pair of antennae.

3.It usually has a single eye and a compound eye.

4.The chest serves as the center of movement and has 3 pairs of feet.

5.Usually, adults have 2 pairs of wings, but there are exceptions.

6.The abdomen contains most of the internal organs and organs, and is the center of reproduction and nutrient metabolism.

Insects are animals. Insects are the most abundant group of animals on the planet, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses), and they can be found in almost every corner of the world.

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 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.
