Butterflies are a group of insects with complete metamorphosis. This means that there is a drastic change in shape during their life cycle that passes through the egg, larval, pupae and adult stages. Butterflies usually lay their eggs on the leaves of the plants they eat caterpillars. butterflies, laying eggs on nettle, cabbage, brussel sprouts or other plant members that can provide food sources to butterfly eggs that have been hatched.

When the caterpillars hatch from the eggs, they will feed continuously on the leaves of the plants that are at home as well as their source of life to morpheme by biting pieces of leaves with their jaws. In large quantities they can cause extensive damage to the plant.

In order to grow, the caterpillars must repeatedly spill out their outer 'skin' (cuticle) layer and extend their body before the hardening of the cuticle. After a few moults, the caterpillar reaches full size and migrates from the food plant to a protected position, such as a wall or branch of a bush. Here the caterpillar will protect with their outer shell after a considerable squeeze from the results of eating the foliage to become a pupa (cocoon). In some species, the caterpillar also forms the silk cocoon itself before entering the pupating cycle. The stage of the cocoon becomes a 'resting' or an ascetic phase but internally the larvae are being dissolved and replaced by the structure of an adult butterfly, though still limited in this case in a cocoon.

The butterfly ends up splitting the cocoon cuticle and appears. The wings are still weak and easily torn when they first emerge from the cocoon so they must first wait for their wings to expand and harden before they can fly.






The shape of the butterfly is in complete contrast to that of the larvae that gave rise to it. There are two pairs of wings, three pairs of ankles, antennas and compounds. The feeding method is also completely different from caterpillars. The portion of a tubular mouth (proboscis) that can be rolled under the head when the butterfly does not eat. During the meal, the butterfly slipped from its scroll in the proboscis and used it to investigate the flowers in order to suck out the flower-exposed nectar, before they finally had to remove the eggs and continue their bloodline before they finally had to die. the following explanation one by one about the butterfly cycle from egg to adult butterfly.

After mating, females lay eggs in batches of 6-100, usually on the undersides of plant leaves in cabbage families where they are bound by sticky secretions. Eggs are somewhat bottle-shaped, yellow or orange with a striped pattern on its surface It contains egg yolks, maintains the growing larvae, and a small, micropyl hole, at the top, which claims sperm when the egg is fertilized in the female ovum and which now allows air to reach the embryo. In warm weather, after about a week hatching eggs and larvae of small eating caterpillars called the way out of eggshells and gobbling up their remains. Their eggshells, indeed, seem to be important enough for their further development. Next, they eat cabbage leaves, biting the pieces with their jawsCaterpillars. 

Inside the heads of a pair of salivary glands form silk-producing organs, and project their channels in tubes, spinners, behind the jaw. The fluid is secreted by the gland through the spinner and hardened in the air to form a silk thread. The caterpillar uses this to attach itself when walking on a secreting, slippery surface of a zigzag trace of yarn that sticks to the surface and can be gripped by the foot. Simple ocelli eyes, three on each side. They consist of a single lens with a light-sensitive cell underneath. It is possible that they can detect only the difference between light and dark and can not form images. 

The first three body segments correspond to the adult's chest and the remaining ten become part of his stomach. There are ventilators on both sides of the first thorax segment and the first eight stomach segments. Each thoracic segment bore a pair of jointed "right" legs with a claw at the end. This corresponds to the feet of adults. The third for the sixth segment belly bears a pair of unjointed, fleshy projection with a row of small hooks at the end. This is called a proleg and is not present in adults.
