Life Cycle of an Insect
The life cycle of an insect has four stages.
It is called “metamorphosis.”
Stage 1A butterfly starts life as a very small, round or
oval egg.
Stage 2When the egg finally
hatches, a caterpillar (larva) comes out.
The caterpillar then eats the leaf it was born on and
grows big quickly.
Stage 3As soon as a caterpillar is
done growing, they form into a pupa.
It may look like the caterpillar is just resting from
the outside, but inside the caterpillar is rapidly
changing.
The caterpillars are going through ‘metamorphosis,’ to
become a butterfly. Stage 4When the caterpillar has done all of its changing a beautiful butterfly comes
out!
