The process by which a caterpillar turns into a butterfly is: egg, larva, pupa, butterfly (adult).
Butterflies are fully metamorphosed insects. During the larval stage, the butterfly has to eat a lot of leaves and go through several molts, the larva matures into a chrysalis, and when the chrysalis matures, the butterfly breaks out of the chrysalis and drills out of the chrysalis. This is a dangerous period for the butterflies because the butterflies' wings are not yet dry and hardened enough for them to fly.
In the first stage, in order for the caterpillar to have enough food as soon as it is born, the female butterfly lays her eggs on a plant.
Stage 2: The caterpillar has an incredible appetite and can eat more than 20,000 times its own body weight before turning into a chrysalis.
Stage 3, After a few weeks, the caterpillar attaches its tail to a branch with silk and completes its final molt before pupating.
Stage 4: When the butterfly breaks out of its cocoon, it mates, lays eggs, and another cycle of life begins.
Difference between caterpillars and butterflies
Caterpillars generally refer to the larvae of Lepidoptera (moths and butterflies), which has three pairs of thoracic peduncles and about five pairs of gastropods and caudal peduncles, and there are a lot of poisonous bristles on the body of the caterpillar, which will cause the skin to be red and swollen if touched by human beings, and some of which can be used as bait, and the caterpillars are often active in the leaves of the tree, the trunk, and other places. Some caterpillars can be used as fish bait.
Butterflies, arthropods, insects, Lepidoptera, Hammerhorn suborder of animals, the world's more than 14,000 species, most of which are distributed in the Americas, especially in the Amazon River Basin, the most varieties. Butterflies are mostly between 15 - 20cm in size, with the body divided into head, thorax and abdomen, two pairs of wings; and three pairs of feet. In the head there is a pair of hammer-like antennae, the antennae end thickened, the wings are broad, resting wings erect on the back.
