How does the color of the butterfly s wings go up

When the larvae are bored, they eat the pigments that come down from plants, minerals, and so on

I grew it myself, and I didn't have any hands to hold a brush.

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.

Hello, the color of the butterfly is mainly manifested in the wings, the color of the wings is some bright and envious lead, and some are gray and dark; The bright appearance of butterflies has a shocking effect on natural predators 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 is easy to use as a camouflage brother at this time; 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 with a microscope is many tiny scales, the reflection and refraction of the scales to sunlight scatters, and the angle of the scales can be changed (like pulling blinds) to control body temperature, so the color of this wing will not change under strong light;Chemistry is the color of the wings that change through the pigment, so this color changes in bright light because the pigment is destroyed by the rays in the sun's rays.
