How do caterpillars turn into butterflies in pupae?

The insect turns into a green or brown hard shell and becomes a pupa that moves without eating, but the body changes drastically inside the shell. After a few days, the pupa becomes an adult worm and the butterfly emerges from the cracked pupal shell. At this point, its wings are folded.

The adult worm dies after laying eggs, and the eggs develop and hatch into caterpillars. Now you understand that the life of a butterfly has to go through eggs. Larvae.

Chrysalis. There are four stages of adulthood. The larval stage is harmful to humans and eats the leaves of crops.

However, most adult butterflies or moths can help plants spread pollen, which is also beneficial to humans. After pupation, the interior is completely liquefied, and the gene controls the remodeling and growth of the bud body (adult organ), and after the corresponding position of the pupae completes the adult change, it will break the pupa and emerge under suitable weather conditions. After spreading its wings to dry, the butterfly enters the adult stage.

The caterpillar becomes a butterfly should be a wonderful life change process in the world, in just one week to a few weeks (largely depending on the species and environmental temperature of the caterpillar), the complete pupa is gently pierced with a sharp needle is this green liquid spewed out, after fully opening it is found that it is basically all green liquid, and it is rare to find a complete form of organ, it is certain that at this stage, the body of the pupa undergoes violent decomposition and reorganization work, Many cells are digested from existing tissues and used to reorganize other organs in the body to develop new functions. For example, most of the muscle tissue of caterpillars is digested into individual cells, which are then used to synthesize other new tissues in the body, but in the process, some organs do not change much. <>

The life cycle of a butterfly is 9 months, and its growth process is that of an egg, a caterpillar, a pupa and a butterfly.

Butterflies, commonly known as "butterflies", are 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.

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.

Flying silently. The reason why we can hear sound is caused by the vibration of their wings, and the action of the vibrational waves that travel in the air on the ears. Our ears perceive waves that vibrate 16 20,000 times per second, and within that range we feel sound. Waves above or below this range we don't feel sound.

Butterflies flapping their wings only 4 10 times per second, and the frequency of butterfly flapping is low, and it travels to our ears through the air, so we can't feel it, and we can't hear the sound of their flight.

The process of caterpillar transformation into butterfly is divided into four stages: embryonic stage (egg), butterfly larva, butterfly pupae, and butterfly adult. The caterpillar becomes a butterfly, it is a relatively long process, first of all, the butterfly lays its eggs on the leaves under the suitable temperature leakage skin, and the eggs need to eat the egg shell and many green leaves to supplement nutrition after the eggs become larvae, and the larvae will spin silk and fix themselves on the branches after maturity, and it will take about two weeks to metamorphose into a butterfly.

Caterpillars generally refer to the larvae of lepidopteran (moths and butterflies). It has 3 pairs of thoracic feet, most of the gastropods and caudal feet are 5 pairs, and some larvae have a lot of poisonous bristles, which will be red and swollen when people touch them.

Caterpillar appearance characteristics: beautiful color, adult body limbs and wings are covered with scales and hairs, so the two pairs of wings are scaly, and the forewings are larger than the hindwings; siphon mouthparts (primitive small-winged moths have a repatriation of the upper jaw, which is chewing); antennae filamentous, bictenoid, ctenoid, club-shaped and other types; The compound eye is well developed, with 2 or no single eye. The larvae are worm-like, with 3 pairs of thoracic feet, and most of the gastropods and caudal feet are 5 pairs.

The larvae have bristles on their bodies, which are of great significance in the classification of the arrangement of the bristles and the order of the hairs. There are about 112,000 species, including moths and butterflies. Some of them can be used as bait and fish feeding, and are often active in leaves, trunks, etc., and are often found in spring and summer.

The process by which a caterpillar becomes a butterfly

Mother butterflies lay their eggs on leaves when the temperature is right. After a few days, the larvae inside gradually grow up, and when they have the strength to break through the eggs, they will burst out. Their life journey is very long, so they have to keep eating and eating themselves.

After two weeks of eating like crazy, they become very obese.

Before metamorphosing, they will fix themselves to the branches, and then spend two weeks, dissolving their bodies until they become a bag of nutrient-rich liquid, their cells can be reborn, slowly turning into feet, wings, tentacles, etc., when they mature, a beautiful flower butterfly penetrates the resistance of the shell.
