1 The Life Cycle of a Butterfly
Content Area: Science Grade Level: Second grade

2 Four Stages: The egg, Larva, Pupa and Butterfly

3 The Egg Stage 1 A butterfly starts its life as a tiny round egg.
. Butterfly eggs are usually laid on the leaves of plants. If you look closely, you can see the tiny caterpillar growing inside.

4 The Larva Stage 2 Butterfly larvae are actually what we call caterpillars. Caterpillars do not stay in this stage for very long and mostly, in this stage all they do is eat.    Caterpillars need to eat and eat so they can grow quickly. When a caterpillar is born, they are extremely small. When they start eating, they instantly start growing and expanding.  Their exoskeleton (skin) does not stretch or grow, so they grow by “molting” (shedding the outgrown skin) several times while it grows.

6 THE PUPA Stage 3 As soon as a caterpillar is done growing and they have reached their full length/weight, they form themselves into a pupa, also known as a chrysalis.  Inside, the old body parts of the caterpillar are undergoing a transformation, called ‘metamorphosis’. Tissue, limbs and organs of a caterpillar have all been changed by the time the pupa is finished, and is now ready for the final stage of a butterfly’s life cycle.

8 The adult butterfly When the butterfly first emerges from the chrysalis, both of the wings are going to be soft and folded against its body. This is because the butterfly had to fit all its new parts inside of the pupa.  As soon as the butterfly has rested after coming out of the chrysalis, it will pump blood into the wings in order to get them working and flapping – then they get to fly.
