The Butterfly Life Cycle
A butterfly usually lays 200-500 eggs on plant leaves and stems. Eggs from different butterflies are different shapes and sizes. The caterpillars hatch from the eggs about 5 days later.
The caterpillar is also called the larva. Caterpillars first eat their eggshell, then they eat lots of leaves. Each time the caterpillar grows, it needs to shed its old skin or molt. They usually molt 5 times. After a few weeks the caterpillar stops eating and growing and looks for a place to change.
The caterpillar sheds its skin for the last time and becomes a pupa. The pupa stays inside a hard shell called a chrysalis. Inside the chrysalis, the pupa is changing from a caterpillar's body to a butterfly's body.
The adult butterfly emerges from the chrysalis after several weeks. The butterfly looks for another butterfly to mate with. After mating, the female butterfly lays her eggs. Adult butterflies usually live for only 2 weeks!

Butterflies are beautiful, flying ___________________ that have large scaly wings. Like all insects, they have ___________________ jointed legs, 3 body parts, a pair of antennae, compound __________________, and an exoskeleton. The three body parts are the head, thorax (the ___________________), and abdomen (the tail end).
The butterfly's body is covered by tiny sensory hairs. The four wings and the six legs of the butterfly are attached to the thorax. The thorax contains the muscles that make the legs and wings move.
Butterflies and moths undergo complete ___________________ in which they go through four different life stages.
· Egg - A ___________________ starts its life as an egg, often laid on a ___________________.
· Larva - The larva (___________________) hatches from an ___________________ and eats leaves almost constantly. The caterpillar molts (loses its old ___________________) many times as it grows. The caterpillar will increase up to several thousand times in size before pupating.
· Pupa - It turns into a pupa (chrysalis); this is a resting stage.
· Adult - A beautiful, ___________________ adult emerges. This ___________________ will continue the cycle.
Life Cycle
Egg
The Painted Lady female lays its eggs on the plant it eats. The eggs are the size of a pin head. When the butterfly lays its egg it's a pale green .
The caterpillar eats non-stop 5-10 days. The caterpillar molts 5-6 times during the larval stage. When the caterpillar has grown full size it starts to pupate.
Larva
Pupa
When the caterpillar turns into a pupa it turns into liquid and reforms into a beautiful butterfly. Then it pushes its way out of the pupa.
The butterfly has scales on its wings. When the adult butterfly comes out of its pupa it hangs itself upside down and pumps blood into its wings inflating them. The butterfly has to wait for its wings to dry before it can fly.
