Why are butterfly wings colorful?

Butterflies have a tiny layer of scales of different shapes growing on their wings. The scales contain a number of special chemical pigment particles, which are combined to form a colorful pattern. There are also horizontal stripes growing on the scales, and the more such stripes, the more beautiful and colorful the light shines.

It turns out that there is a layer of scales on the wings of butterflies, and the scales contain various chemical pigment particles. When these chemical pigment particles are densely combined, they become colorful patterns. There are also many ridges on the wings of butterflies, and the more ridges, the more shapes the pattern will be.

That's why we can see <>

Butterflies of all kinds. Butterflies have colorful wings, not just for the sake of beauty, but also as a protective color, allowing the butterfly to hide itself in a similar color to the wings when it encounters enemies. In this way, the enemy will not easily detect its tracks, and it can escape the catastrophe.

Colorful butterflies fly around among the flowers, making for a beautiful landscape. The wings of the butterfly shimmer in the sunlight with colorful lightWhen we touch the butterfly's wings with our hands, a layer of "powder" sticks to our hands, and then we look at the butterfly's wings, which become transparent because they have lost their beautiful color.

Why is that? It turns out that there will be a layer of "powder" sticking to the hands, and then look at the wings are not "powder", but a layer of small scales. There are elongated, round and triangular ones, arranged neatly and evenly.

The scales of a white butterfly are white, while the scales of a colored butterfly are of various colors. The scales of various colors are arranged symmetrically and regularly on the two pairs of wings, making the wings very beautiful. <>

These small scales attach to the wings and are not as strong as fish scales, and often fall off when touched by hand, stick to our hands, and become a fine powder. Butterflies in the morning are always clumsy, unable to fly fast or high. Why is that?

It turned out that the temperature in the morning was low, the air flow was not very active, and the butterfly had no external force to rely on, and its large wings not only could not enhance the ability to fly, but became a burden to fly. In addition, there is dew in the morning. The butterfly perches among the dense grasses, and its wings are inevitably wet with dew, which increases its weight, which also increases the difficulty of its flight.

Butterflies have tiny scales on their wings, and these scales contain many special chemical pigment particles, which combine to form colorful patterns on the butterfly's wings. In addition, there are many horizontal ridges on the scales, and the more ridges there are, the more patterns and shapes on the butterfly's wings. Although the chemical pigments on these scales are magnificent in color, they will gradually fade or disappear due to oxidation.

Therefore, sometimes we see that a certain part of the butterfly's wings is left with only a transparent membrane.

The front and back of the butterfly have colorful, ever-changing markings, and how the color of these markings is formed. In a nutshell, there are 3 types of colors on butterflies, namely pigmented, structured and mixed. Pigment color, also known as "chemical color", is formed by the presence of pigment granules.

Pigment granules have different chemical compositions and different absorption or reflection of light waves. Butterfly wings are <> on scales

The wings of butterflies of countless different colors are covered with a layer of tiny scales, and these scales contain many special chemical pigment particles, which are combined to form a colorful pattern on the butterfly's wings. The more patterns and shapes there are on the wings of butterflies.

Why are butterfly wings colorful?

The color of butterflies is mainly manifested in the wings, and the color of the wings is bright and grayish; The bright appearance of butterflies has a shocking effect on natural enemies and nemesis, and they dare not approach or prey, such as highly venomous snakes and colorful caterpillars; The color of some butterfly wings is withered yellow, such as withered leaf butterflies, which plays the role of camouflage; Some butterflies have one or more eyes on their wings, which also serve as a deterrent to predators.

In fact, the important role of wings is to regulate body temperature just like human **, and there are many scales on butterfly wings (a bit like fish scales). The color of the wings is divided into physical and chemical colors; The physical color is through the scale powder, which is seen by a microscope is a lot of tiny scales, the reflection and refraction of the scales to the sunlight scatters, and the angle of the scales can be changed (like pulling blinds) to control body temperature, so under strong light, the color of this wing will not change; Chemistry changes the color of the wings through the pigment, so this color changes in bright light because the pigment is destroyed by the rays in the sun's rays.

1. There are many colors of butterfly wings, such as pink, yellow, purple, white, red and white, blue, brown, and even color.

2. The color and pattern on the butterfly's wings are given by the scales.

3. However, the color of the scales is also divided into physical color and chemical color.

4. On the wings of most butterflies, the scales themselves have chemical color, that is, color, just like pigment. But the electron microscope cannot see the color of the object at all, only the microstructure of the object. Colored and colorless things look the same under the electron microscope.

Chong Xun. 5. However, there are a considerable number of species in the family Flashpteridae, and the scales on the wings have no color (chemical color). However, the scales themselves have a precise microstructure, which can reflect and refract light of a specific wavelength and arrange them neatly on the wings, so that the butterfly wings have the reflection of metallic blue, green, purple and other colors. If the internal microstructure of the scales on the wings of this type of butterfly is damaged, or the chain structure of the pinned chain, the glittering metal will be destroyed.

It is a physical color (structural color).

6. In addition: if the scales on the wings are wiped off, it will produce panchromatic iridescent on the transparent fin membrane body due to physical and optical effects such as film interference. This phenomenon is also seen in the butterfly genus Silky Eye Butterfly from South America, which has almost no scales on its wings (natural reasons, it has evolved transparent wings without scales, which can hide in the shadows when it travels through the forest, without being detected by enemies, reducing the rate of predation by predators), and at a certain angle you can observe blue-purple iridescent colors on the wings.
