What are butterflies made of?

Butterflies are transformed from pupae.

Butterfly is a completely abnormal insect, which will go through four stages in its life: egg, larva, pupa and butterfly. First the eggs, then the larvae. After growing for a period of time, when it is mature, it begins to spin silk and cocoon, becoming a pupa. After a period of time, it becomes a butterfly, biting through the pupa and emerging.

The metamorphosis process of butterflies

1, butterfly eggs are generally round or oval, with a waxy shell on the surface to prevent water evaporation, and a fine hole at one end, which is the channel for sperm to enter. The egg size of different kinds of butterflies varies greatly. Butterflies usually lay eggs on the leaves of plants that larvae like to eat to prepare food for larvae.

2. After the larvae hatch, they mainly eat food and eat a lot of plant leaves. Larvae have different shapes, most of them are carnivores and a few are caterpillars. Butterflies mainly harm agriculture in the larval stage. As the larva grows, it usually goes through several molts.

3. Larvae will become pupa when it matures. Generally, larvae are fixed in a hidden place on the back of plant leaves with a few iron wires, and then pupate directly without cocoon formation.

4. After the pupa matures, it breaks out of the cocoon, but it takes some time for the wings to dry and harden. At this time, butterflies can't avoid natural enemies, which is a dangerous period. After the wings are spread out, the butterfly can fly, and the front and rear wings of the butterfly are out of sync. So when the butterfly flies, it fluctuates greatly and its posture is beautiful. The so-called dancing comes from the flying of butterflies.
