Butterfly lifespan : A wide variety of butterflies are found around the world. Butterflies are formed by a process called metamorphosis. It is a Greek word. This means change.
Insects usually have two metamorphoses. Locusts, crickets, dragonflies and cockroaches have undergone an incomplete transformation. Its young creatures are called nymphs. Its young creatures generally resemble large creatures but do not have wings.
Some types of insects have complete metamorphosis. They are butterflies, beetles, flies, moths and bees. Its young one is called larvae instead of nymphs. These are completely different from adults.
It loves to eat a wide variety of plant leaves. Notable among them are mulberry leaves. They also like the leaves of plants such as Asoka, curry leaves, lemongrass, castor, silk cotton, calotropis, cassia and citrus.
There are four stages in its life cycle. They are the egg stage, the larval stage, the pupa stage and the adult stage.
Well-developed female butterflies lay their eggs at the base of the leaves of some plants. The leaves of these plants are used as food for growing young organisms.
Laying seasons vary depending on the type of silkworm. Female butterflies lay many eggs at once. Their eggs are very small. Larvae emerge from most of these eggs.
The next stage of the silkworm is the larva. The larvae of the silkworm are called caterpillars.
The caterpillar eats the leaves of the plant and becomes a large caterpillar. At this time the larva is 100 times larger than its initial size. The food thus eaten is used until the next long pupa stage. As the caterpillar grows, its skin peels off 4 to 5 times. The caterpillar, which hatched from a small egg, is now 2 inches long.
Once the caterpillar is fully grown it will become its next stable pupa. This stage of the silkworm is called chrysalis.
Depending on the type of silkworm, the pupae place itself under a branch or leaf and form a nest around itself. Within this nest it grows safely. This condition can last for more than a few weeks. In some species the pupa stage lasts for more than a year.
Within this nest the young one of the silkworm undergoes many changes. The specialized cells of the larvae grow rapidly subject to new changes. Here the well-developed silkworm develops large wings, thick legs, joint eyes and antennae.
The last stage of silkworms is adult. It is found to be completely different from the larval stage. The caterpillar has small eyes, thick legs and small antennae. Adults are found with large compound eyes, large colorful wings, long legs and antennae. They fly effectively using their beautiful wings.
The job of the caterpillar is to become a nourishing organism. Adults engage in mating and form the next generation. Silkworms feed on nectar in flowers and receive energy/
Silkworms live for only one or two weeks. Some types of silkworms can live up to a few months. In the life cycle of the silkworm its next generation will start again from its egg.
