The chrysalis of a caterpillar is where they transform into the butterfly. It can take on many shapes,
and is usually a brownish-green color. A typical larva will pupate usually on the back of a leaf, attached by a thin silk
thread. The process can take from a few weeks up to several years.
When the butterfly is finally fully developed, it will swallow some air and pumps itself
up, breaking the skin of its chrysalis. It will then climb to a spot where it can hang upside-down and pump its very soggy
wings so as to force blood into the tiny veins. Eventually the wings dry out and become hard, and the butterfly is ready for
the rest of its life.
