SAY While the process of complete metamorphosis looks like four very distinct stages, continuous changes actually occur within the larva. The wings and other adult organs develop from tiny clusters of cells already present in the larva, and by the time the larva pupates, the major changes to the adult form have already begun. During the pupal stage the transformation from larva to adult is completed. Butterflies do not spin a cocoon to protect them as pupae and their pupa stage is often called a chrysalis. Pupae are much less mobile than larvae or adults, yet they often exhibit sudden movements if they are disturbed. Many butterfly pupae are well-camouflaged, since they can't escape from predators by flying away. Just before the butterfly emerges, their wing patterns are visible through the pupa covering, This is not because the pupa becomes transparent; it is because the scale color only develops at the very end of the pupa stage, The pupa stage usually last ten to fourteen days under normal summer conditions. Ever wonder where a butterfly comes from? It comes from a chrysalis (KRIS-us-liss) which is also called a pupa. A chrysalis looks like a tiny leathery pouch. You can find one underneath some leaves in summer. Some animals don't change much as they grow up. Think about it: someone your age looks a lot like a grown-up. Grown-ups have more wrinkles and gray hair. But they still have two arms, two legs and one head --just like you. We have been studying an animal that's very different - the butterfly. Butterflies go through four life stages, and they look very different at each stage.

Lesson 5

BUTTERFLY EMERGING FROM CHRYSALIS HERE'S WHAT YOU DO: 1) Cut out and color a butterfly from the heavy paper. Use any color, but make both halves look the same. Put a small hole at the top of the butterfly's head.

2) Color the toilet paper tube to look like a chrysalis. (Most are green, but you can use any color.)

3) Take a piece of pipe cleaner and shape it like the letter "V". Put one point through the little hole in the butterfly's head and then twist it to look like antennae, Butterflies use these "feelers" to learn about their environment.

4) Glue the butterfly to one end of the pop stick. Let the glue dry. 5) Curl the butterfly's wing and slide it into the chrysalis. 6) Pull the stick to make the beautiful butterfly come out of the chrysalis. Fly your butterfly like a real one!
