Is a bird an insect Is a butterfly a bird or an insect? Why?

Not insects. It is a vertebrate.

1. Birds: oviparous vertebrates covered with feathers on their bodies.

Morphological characteristics: Birds are bipedal, homeothermic, oviparous vertebrates covered in feathers, with forelimbs evolved into wings, beaks and no teeth. The body is streamlined (spindle-shaped) and most of the flight lives.

The pectoral muscles are developed, the rectum is short, the amount of food is large and the digestion is fast, that is, the digestive system is developed, which helps to lose weight, is conducive to flying, the heart has two atria and two ventricles, and the number of beats is fast. Constant body temperature. In addition to the lungs, the respiratory organs also have air sacs formed by protruding from the lung walls to help the lungs breathe twice.

2. Insects: Insects belong to the arthropods among invertebrates.

Morphological characteristics: The body of the 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 born on the head, and the bones are wrapped around the body, and the shape changes many times throughout their lives.

Insects are structurally different 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.

Extended Materials. a) Vertebrates.

Refers to animals with vertebrae and is a subphylum of chordates. The largest number, the most complex structure, and the highest evolutionary status, evolved from mollusks. The morphological structure is very different from each other, and the lifestyles are very different.

Vertebrates are generally symmetrical in shape, and the whole body is divided into three parts: head, trunk, and tail, with relatively complete sensory organs, motor organs, and a highly differentiated nervous system. It includes six categories: roundmouths, fish, amphibians, reptiles, birds and mammals.

b) Invertebrates.

Invertebrates, are animals that do not have a vertebral column on the dorsal side, and they are the original form of animals. Including protozoa, echinoderms, molluscs, flattened animals, annelids, coelenterates, arthropods, nematozoa, etc.

Insects are characterized by a structure of 3 pairs of legs, head, thorax and abdomen.

Whereas, birds belong to the category of birds.

So birds are not insects.

Butterflies are insects, not birds, because butterflies are cocooned into butterflies by caterpillars, and birds are egg-born, and not all that can fly are birds, like bats are not birds.

Butterflies are insects, which conform to the characteristics of insects, a class of arthropods, and the body is divided into three parts: head, thorax, and abdomen. The head has antennae, eyes, mouthparts, etc.

Butterflies are insects because the predecessor of butterflies is caterpillars, and then caterpillars become butterflies by cocooning. And butterflies and birds, you can also see by looking at the comparison, birds have fluffy feathers on their bodies.

Butterflies belong to insects, it belongs to the class of insects, has three parts of the head, thorax, abdomen, and also has compound eyes, generally speaking, only insects will have compound eyes, and birds only have eyes, there are no compound eyes.

Butterflies are naturally insects, and birds are bipedal, homeothermic, oviparous vertebrates, covered with feathers, forelimbs evolved into wings, beaks and no teeth, and these characteristics of butterflies are not satisfied.

Butterflies are insects, not birds, because butterflies and birds as a whole are too different, birds have feathers, claws are homeothermic animals, and butterflies do not have these.

Butterflies are, of course, insects, and they do not belong to birds, because butterflies possess the characteristics of insects, but not birds.

Butterflies, of course, belong to the category of insects. Because butterflies themselves are made of insects, birds are animals that do not change into various forms at all. So butterflies are a class of insects and not birds.

Butterflies belong to the class of insects, butterflies are the general name of the phylum Arthropods, insects, hammerhorn suborder animals, butterflies are generally brightly colored, there are many stripes on the body, and there are various spots on the wings and body.

Butterflies belong to the class of insects. Arthropods have a thick exoskeleton made of chitin on the surface of their bodies. Generally, each body segment has a pair of segmented appendages, also called arthropods.

Butterflies are insects, which is because their wings are very thin and small, which are very different from the flight of birds.

Is a butterfly a bird or an insect and why? Butterflies are insects, not birds. Because butterflies belong to the insect family.

Insects are of great variety and morphology, belonging to the arthropods of invertebrates, and are the most numerous 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 man, more than all other animal species combined, but many species are still to be discovered. The most common are ants, butterflies, bees, dragonflies, flies, cockroaches, etc.

The basic characteristics of insects can be summarized as follows: the body has three heads, thorax and abdomen, 2 pairs of wings and 6 legs, 1 pair of antennae is born on the head, and the skeleton is wrapped around the outside of the body; It has many changes in form throughout its life, and is the most diverse of arthropods in the world.

BirdsBirds are a group of vertebrates adapted to flight life that evolved from ancient reptiles, and it is likely that they evolved from theropod dinosaurs.

The main characteristics of birds are: bipedal, homeothermic, oviparous vertebrates with streamlined bodies (spindle or fusiform), and most of them live in flight. The body surface is covered with feathers, and the forelimbs generally become wings (some species have vestigial wings); The rectum is short, the amount of food is large and the digestion is fast, that is, the digestive system is developed, which helps to lose weight and is conducive to flying; In addition to the lungs, the respiratory organs also have air sacs formed by protruding from the lung walls to help the lungs breathe twice.

The ostrich has vestigial wings, the sternum is small and flattened, there is no keel protrusion, and it cannot fly. Penguins are degraded seabirds with fin-like wings that have lost the ability to fly.

Insects are boneless animals that belong to the class Insecta in the phylum Zodia. Birds are bony animals and belong to the category of birds. The digestive system of insects is simple, and the digestive system of birds is complex:

contains the stomach; intestines, liver, etc. (basically the same as humans). Insects inhale gas through the stomata on both sides of the abdomen of the body and then use the nerve trunks of the body to metabolize the cells, while birds exchange oxygen with the functional groups of the lungs.

"Insects and birds" is correct, and the specific explanation is as follows:

Pinyin: [ chóng niǎo ].

The meaning is as follows: 1. Refers to snakes and birds.

2. It generally refers to insects and birds.

3. That is, the insect book.

4. Generally refers to words.
