The pupa of many moths is protected inside a coccoon of silk. This is important because caterpillars can't travel far.
As the caterpillar grows it splits its skin and sheds it about 4 or 5 times. Several species When a butterfly emerges from a chrysalis its wings are crumpled. Once the caterpillar is firmly in place the exoskelton will split off exposing the pupa. The one thing they can't do is grow.The caterpillar's job was to eat. The adult female can easily fly from place to place to find the right plant for its eggs. The life cycle of a butterfly is truly amazing.
Not all butterfly species attach in the same way. Most butterfly species will stay in the chrysalis for about 1-2 weeks before the butterfly emerges.

The caterpillar on the right is in its fifth instar and will soon pupate, or molt, one last time to become a chrysalis. The first stage is the egg, which hatches about 4–7 days after being laid. Caterpillars do not stay in this stage for very long and mostly, in this stage all they do is eat. Many adult butterfly species lay hundreds of eggs with only a few surviving to become adults.The picture on the left shows a Black Swallowtail caterpillar getting ready to pupate or form a chrysalis. The first meal for most caterpillars is the eggshell. ; Larva - The larva (caterpillar) hatches from an egg and eats leaves or flowers almost constantly. Each time they do their appearance will change, sometimes rather dramatically.Black Swallowtails, for example, have five instars or five different stages between the hatching from the egg and the time of pupation. Caterpillars are subject to weather conditions, disease, parasites and predators.
When ready to pupate, the monarch caterpillar attaches itself to the underside of a leaf or other surface with a sticky silk pad.
This stage can last from a few weeks, a month or even longer. It hangs upside-down and sheds its yellow and black skin, revealing the leaf-green protective shell of the chrysalis underneath.
It has made a silk mat and attached itself at the base. Then the butterfly must wait several hours for the wings to harden and dry before it can fly away.The lifespan of most adult butterflies is about 2-3 weeks but this can vary greatly among species. The butterfly and moth develop through a process called Insects have two common types of metamorphosis.
In the case of the Black Swallowtail the final chrysalis will be either green or brown depending on whether the caterpillar is pupating on a green stem or a brown stick.
Some species of adult butterflies get energy by feeding on nectar from flowers but many species don't feed at all. Click photo to go to our monarch butterfly life cycle page.. You can find out about each of these stages on this page: The Life Cycle of the Monarch Butterfly What many people don’t know is that the monarch caterpillar itself has five stages of development.At the end of each stage the caterpillar molts (moults in British English). The pupal stage of a butterfly is known as a chrysalis. The Academy of Natural Sciences of Drexel University Eggs are laid on plants by the adult female butterfly. Butterflies and moths undergo complete metamorphosis in which they go through four different life stages. The adult stage is what most people think of when they think of butterflies. The caterpillar is designed to be an “eating-machine” and before it begins to pupate it will increase its body mass thousands of times.The picture on the left is a small young Black Swallowtail larva while the caterpillar in the picture on the right is an older Black Swallowtail larva. The job of the caterpillar is to eat and eat and eat.
Food eaten at this time is stored and used later as an adult. The caterpillar also spun a string of silk around its body and attached the strings to the branch to hold the chrysalis in place in the same way that a telephone linesman uses a leather belt to attach to the pole. This is also called a caterpillar if the insect is a butterfly or a moth. The adults have long legs, long antennae, and compound eyes. Females lay a lot of eggs at once so that at least some of them survive.The next stage is the larva.
