A caterpillar is in the Larva stage. When it goes into it's cocoon it will be in the pupa stage. When it hatches, it will become a butterfly (and therefore be in the adult stage)
The second stage in a butterflies' life is caterpillar.
Grasshoppers do but butterflies (the ADULT stage of a caterpillar) do not (the caterpillars do though).
An adult butterfly is called just that. In the larva stage it is called a caterpillar. The process is called metamorphosis.
That's the pupal stage-the caterpillar undergoes metamorphosis and adult butterfly emerges.
An adult caterpillar is not a caterpillar. It's a butterfly or moth! There are many different species.
Monarch butterflies go through a four stage development cycle in their lifespans. The four stages of the monarch butterfly are the egg, the caterpillar or larvae, the chrysalis or pupa, and the butterfly.
CATERPILLAR
Larvae turn into adults through the process of metamorphosis. This process starts after a larva turns into a pupa. It then emerges from the pupal stage in its adult form.
Actually, I don't really know...
I'm not certain that this is always the case, but I heard that most caterpillars will go into a comatose state, as their body liquidates. They release a bunch of chemicals into the liquid caterpillar mixture which direct the reassembly process that ultimately results in a butterfly or moth.
Concerning the life cycle of insects, the larva stage comes before the pupa stage. The pupa stage is followed by adulthood.
