Life Cycle of an Insect

The life cycle of an insect has four stages.

It is called “metamorphosis.”

Page 29: Insects

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.

Page 30: Insects

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!
