The Caterpillar Who Became A Butterfly .

In some species, these imaginal discs remain dormant throughout the caterpillar's life; in other species, the discs begin to take the shape of adult body parts even before the caterpillar forms a chrysalis or cocoon.
Some caterpillars walk around with tiny rudimentary wings tucked inside their bodies, though you would never know it by looking at them. Once a caterpillar has disintegrated all of its tissues except for the imaginal discs, those discs use the protein-rich soup all around them to fuel the rapid cell division required to form the wings, antennae, legs, eyes, genitals and all the other features of an adult butterfly or moth.
The imaginal disc for a fruit fly's wing, for example, might begin with only 50 cells and increase to more than 50, cells by the end of metamorphosis. Depending on the species, certain caterpillar muscles and sections of the nervous system are largely preserved in the adult butterfly.
One study even suggests that moths remember what they learned in later stages of their lives as caterpillars. Getting a look at this metamorphosis as it happens is difficult; disturbing a caterpillar inside its cocoon or chrysalis risks botching the transformation. But Michael Cook, who maintains a fantastic website about silkworms , has some incredible photos of a Tussah silkmoth Antheraea penyi that failed to spin a cocoon. But she had wings.
Earth is our chrysalis. On paper, a butterfly never dies.
The weight of the wings
The saddest and deadest of things is yet so like the gayest and most vital of creatures? It grows with the wings of love and compassion.
So I became a butterfly so you would never leave. It's obscene fluttering corrupted me into darkness. Butterfly eggs are usually laid on the leaves of plants, so if you are actively searching for these very tiny eggs, you will have to take some time and examine quite a few leaves in order to find some. When the egg finally hatches, most of you would expect for a butterfly to emerge, right? Butterfly larvae are actually what we call caterpillars.
Butterfly Life Cycle / Butterfly Metamorphosis
Caterpillars do not stay in this stage for very long and mostly, in this stage all they do is eat. When the egg hatches, the caterpillar will start his work and eat the leaf they were born onto. This is really important because the mother butterfly needs to lay her eggs on the type of leaf the caterpillar will eat — each caterpillar type likes only certain types of leaves. Since they are tiny and can not travel to a new plant, the caterpillar needs to hatch on the kind of leaf it wants to eat.
How caterpillars gruesomely transform into butterflies
Caterpillars need to eat and eat so they can grow quickly. When a caterpillar is born, they are extremely small. When they start eating, they instantly start growing and expanding.

From the outside of the pupa, it looks as if the caterpillar may just be resting, but the inside is where all of the action is. Inside of the pupa, the caterpillar is rapidly changing. Now, as most people know, caterpillars are short, stubby and have no wings at all. Finally, when the caterpillar has done all of its forming and changing inside the pupa, if you are lucky, you will get to see an adult butterfly emerge. When the butterfly first emerges from the chrysalis, both of the wings are going to be soft and folded against its body.
A tale of transformation from caterpillar to butterfly
This is because the butterfly had to fit all its new parts inside of the pupa. As soon as the butterfly has rested after coming out of the chrysalis, it will pump blood into the wings in order to get them working and flapping — then they get to fly. Usually within a three or four-hour period, the butterfly will master flying and will search for a mate in order to reproduce.
