Anonymous users2024-02-11The beautiful color on the wings of a butterfly is completely different from other ordinary animals, it does not come from the cells on its body but from the color of its scales. A scale is not a cell, but a so-called cell derivative that is secreted outward by the cells that make up the wing membrane. The scales are usually flattened and feathered, but at the base they are constricted into a needle-like stalk and penetrate into the wing membrane.
Usually the scales are gently attached to the wing membrane and fall off easily. If we look at the wings of a butterfly with a microscope, we will find that thousands of these scales are systematically and neatly arranged on the wing membrane, so that the whole wing takes on a certain color and color depending on the species. Some scales contain countless colors of nude-grained pigments, the color of which is the same color as the substances we see every day, and we call them chemical colors or pigment colors.
However, some kinds of butterfly wings flash or change color due to the type of light source and light direction, these are called physical colors or structural colors, this kind of scales can not find color when observed under the microscope, the scales themselves are transparent, but its surface has a special physical structure, usually there are many deep grooves that go longitudinally, and there are more dense and periodic dense row structures in the grooves, so that they can have different refraction, interference and diffraction after receiving external light, Then reflect some of the light of special light frequency and produce a brilliant metallic luster, of course, this kind of wings will produce different depths and even different colors at any time due to the different types and directions of light, if the light passes through the back of the wings, that is, because there is no light to reflect, its wings suddenly become transparent and colorless.

Under the microscope, the scales on the butterfly's wings are arranged in an orderly and neat manner like tiles on the roof. If it is "disordered and messy", then there will be no pattern on the butterfly's wings.
Moreover, the opening and closing of the scales can also play a role in regulating body temperature.
Features of butterfly wingsSome of the color and pattern of the butterfly's wings are caused by the pigment contained in the scales, while others are caused by the stripes on the surface of the scales that disperse the light and produce a blue or bronze metallic luster. Different colors and patterns can be used to intimidate, alert or conceal the effect. The pearlescent yellow-coated butterfly in Taiwan's Lanyu Township is famous for the metallic luster of its hindwings, which is due to the structural color caused by the special surface structure.

Anonymous users2024-02-09The scales on the butterfly's wings not only make the butterfly gorgeous, but also look like a raincoat for the butterfly. Because the scales of butterfly wings are rich in fat, which protects the butterfly, butterflies can fly even when it rains lightly.
The scales have a structural color, a photonic crystal structure that is stacked on the scales. When there are many tiny structures on a surface that are smaller than the wavelength of light, generally in size of hundreds of nanometers, and have a regular arrangement, it can lead to the selective transmission of light of certain colors, and the light of certain colors is strongly reflected, which is called photonic crystal.
Photonic crystals can show different colors by changing the size of the microstructure and different arrangements in the field, and the colors are also different due to the change in the angle of light. According to different angles, the bright color luster of insect carapaces, butterfly wings, bird feathers and other bright colors in nature is due to the formation of a structure similar to photonic crystals.
Butterflies are made of caterpillars, and the more beautiful the butterfly, the more beautiful the caterpillar before it.
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. >>>More
According to Chen Jianzhi, an associate professor at the Department of Natural Science Education at Taipei Normal University, the butterflies circulating on the Internet are real; Teacher Chen once looked at the butterfly garden in the United States, and by comparing the patterns on the wings, he confirmed that the scientific name of this butterfly is gretaoto, and the Chinese name is "through the winged butterfly", which belongs to the nymphalidae family and the subfamily ithomiinae of the butterfly family. >>>More
Lilies are known as the "fairy of clouds". Because of its elegant and pure appearance, the Catholic Church uses the lily as a symbol of Mary, while the Vatican and France use the lily as a symbol of national independence and economic prosperity and make it the national flower. The bulb of the lily is formed by the scales, and it also means "a hundred years of good harmony" and "a hundred things agree", and the Chinese have regarded it as an indispensable auspicious flower for weddings since ancient times.
1. Golden-spotted beaked butterfly.
There are only 5 subspecies of golden-spotted beaked butterfly, with a body length of about 30 mm and a wingspan of about 110 mm, which is a unique treasure in China, mainly distributed in Fujian, Jiangxi and other places, and is known as the "national butterfly" and "the pride of butterflies", it is the only butterfly in China that is a national first-class protected animal, ranking first among the eight precious butterflies in the world, and is known as "the world's animal living fossil". >>>More
