No, it is then called a pupa.
Butterfly
Egg Caterpillar Cocoon Butterfly
Caterpillars usually go into a cocoon during late-winter or late spring(March-may)
the caterpillar is in it's cocoon for seven days before it turns into a butterfly and comes out. then the butterfly has to sit on the leaf for three hours before it can fly. it's wings have to dry off.
After a caterpillar comes out of the cocoon, it sits on a leaf and flaps its wings slowly to dry them. Once dried, they flap them harder and begin to hover. Then, once they get used to it, They take off!! Butterflies are beautiful! i i {|} {|} ^ | / \ \/ \
They don't weave a chrysalis. They shed their skin, and the chrysalis is what is left under their skin when they shed the final time. Some moth caterpillars weave a cocoon around themselves before shedding skin to form their pupa.
Silk is spun for the cocoon of the silkworm, an insect, before it can turn into a moth. It's vaguely similar to spider web. The silkworm is fed on mulberry leaves.
If you leave it there, and nothing else comes along and eats it, then eventually the bottom of the cocoon opens up and a moth or a butterfly struggles out. It sits in the air for a while drying out, then it flys away. If it's a moth, it lays eggs, never eats, and dies.
The process is called metamorphosis. Metamorphosis is a transformation in which an organism abruptly changes form. Butterflies are hatched from eggs and develop into caterpillars. Caterpillars transform into pupa (chrysalis) then emerge as a butterfly.
The earliest stage is being in the egg. Then comes the caterpillar stage.
Silk comes from the cocoon spun by the silk work. The cocoon is unwound and the silk is then processed for use by humans.
Metamorphosis.
The butterfly forms a cocoon, or "pupa" during the third stage (out of four, total) of it's life. The Caterpillar forms a protection shield called Pupa when it has finished growing. Most of the transformation takes place in side Pupa. This is also known as the "Chrysalis Stage".
