What do butterflies come from? What is the process of butterfly change called

Butterflies are made of caterpillars, and the more beautiful the butterfly, the more beautiful the caterpillar before it.

Butterflies lay eggs in Xin, become larvae, then chrysalis, and finally become worms.

The evolution of butterflies goes through the following four processes. Eggs: Eggs that are normally ready to hatch into larvae after about a week.

The first meal of the young is their own egg shell, which will last for a few weeks, and the weight of the egg will increase to 100 times its original weight. Most larvae undergo five shedding of skin and have different body colors at each instar. Caterpillar:

Don't look at the caterpillar's strange appearance, it's all a trick to disguise yourself. Some caterpillars dress themselves up as bird droppings, while others have long burrs and a variety of warning colors. But even if you come up with all kinds of ways to protect and disguise yourself, sometimes you can't avoid the attacks of natural enemies.

After some struggle, the surviving second-instar butterfly larvae are ready to move on to the next stage. Pupation: In order to successfully complete the next change plan, the well-fed larvae will seize all the time to transform into pupae.

The worms that hide in the pupal chamber will stay for a long time, and after this step of development, some organs will degenerate and disappear; And some organs have been modified; There are also organs that develop newly. Although different insects pupate in much the same way, they pupate in different ways. Feathering:

The last mutation of the butterfly is called feathering. This stage is a very crucial step for butterflies, becoming dazzling for the better, and crippled for the worse. Successful feathering has become the most important task of the butterfly, seize the time to wings, otherwise you will no longer be able to fly in the sky.

The figure may be a little small.

Butterflies go through four stages: egg, larva, pupae, adults, and then become butterflies. Butterflies are commonly known as "butterflies", a collective term for arthropods, insects, lepidoptera, and hammerhorns.

There are about 14,000 species in the world, most of which are found in the Americas, especially in the Amazon Basin. There are 1,200 species in China. Butterflies are generally brightly colored, there are many stripes on the body, the colors are richer, the wings and body have various spots, the largest butterfly spreads its wings up to about 30 32 cm, and the smallest is only about cm.

Butterflies have become an important indicator species of ecological environment because of their sensitivity to ecological changes. The larvae and adults of butterflies have different lifestyles and feed different objects. Many of the adult stage feed on nectar.

In the process of nectar collection, they play a role in pollination for many plants in nature. The larval stage mostly feeds on plant leaves, but also on flower buds, stems, and fruits. If they feed on human food crops or other cash crops, they are called pests.

However, butterfly larvae have different feeding habits due to different species, and some are harmful to fruit trees, such as citrus butterflies; some are harmful to oil crops, such as soybean butterflies; Some are harmful to fibrous plants, such as ramie spotted butterflies; Some are harmful to bamboo, such as arrow-ring butterflies; Some are harmful to forest trees, such as camphor and nan pests, blue ribbon green butterfly.
