The growth process of a butterfly in its lifetime

Butterflies, also known as butterflies, etc., are all metamorphosed insects of the class Lepidoptera, Arthropoda, that is, they go through four stages in their life: eggs, larvae, pupae, and adults. There are about 14000 species in the world, most of which are distributed in the Americas, especially in the Amazon River Basin. Let's take a look at the growth process of butterflies.

Egg

Butterfly eggs are generally round or oval, with a waxy shell on the surface to prevent water evaporation, and a small hole at one end, which is the pathway for sperm to enter. The size of eggs varies greatly among different species of butterflies. Butterflies usually lay their eggs on the leaves of plants that the larvae like to eat, preparing food for the larvae.

Larva

After the butterfly larvae hatch, the main thing is to eat, to eat a large number of plant leaves, the larvae of various shapes, mostly fleshy insects, a few caterpillars. Butterflies harm agriculture mainly in the larval stage, with the growth of larvae, usually after several molting.

Pupa

After maturing, the larva of a butterfly becomes a pupa, usually in a hidden place on the back of the plant leaves, fixing itself with a few wires, and then pupating directly without cocoons.

Adult worm

After the pupa of the butterfly matures, it breaks its shell from the pupa, but it takes a certain amount of time to dry and harden its wings. At this time, the butterfly cannot avoid its natural enemies and belongs to a dangerous period. After the wings are extended, it can fly. Because the front and rear wings do not fan synchronously, the butterfly fluctuates greatly when it flies, and its posture is graceful. The so-called "dancing" comes from the flight of the butterfly. Butterfly adults usually die before winter comes after mating and laying eggs, but some species migrate to the south to spend the winter.
