"The pupa stage is one of the coolest stages of a butterfly’s life. 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. From the outside of the pupa, it looks as if the caterpillar may just be resting, but the inside is where all of the action is. Inside of the pupa, the caterpillar is rapidly changing." (from Learn About Nature site)
I'm going off-line for a bit. Think of it as my chrysalis---it looks as if I may be resting but I'm really just getting a lot of work done...! See you back here!
