Apart from the obvious differences: a butterfly begins life as an egg laid on a food plant. Then, on hatching, as a caterpillar before going through a "complete metamorphosis" to become an adult butterfly. A dog, a mammal, begins life as a puppy, and grows into an adult dog without going through a metamorphosis stage.
An adult caterpillar is not a caterpillar. It's a butterfly or moth! There are many different species.
The younger butterfly may have a similar pattern to the adult
An adult butterfly is called just that. In the larva stage it is called a caterpillar. The process is called metamorphosis.
its name doesnt change its still called a butterfly
If it is a butterfly it is not a baby it is an adult. The immature phase of butterflies and moths takes the form of caterpillars. Generally caterpillars eat leaves but different species feed on different plants.
A Caterpillar is a worm like larva of a butterfly and a nymph is a immature form insect that does not change greatly as it grows e.g. a dragonfly, mayfly or locust. Compared to Larva.
Adult stage.

Actually there's five: egg *caterpillar *Chrysalis *Adult emerges *Adult/ butterfly
So it will be poisonous to bird that want to eat it
Apart from the obvious differences: Butterflies begin their life as caterpillars, then pupate and emerges as a winged adult. Humans begin life as a baby and grow in to an adult without the radical pupate change that affects butterflies.
