6. Changing Chrysalis 

There are four stages in a butterfly’s life-cycle: egg, caterpillar, chrysalis, butterfly.

When the monarch caterpillar is grown, it attaches itself to something and hangs upside down. It quickly forms a protective covering (chrysalis) around itself.

At first the chrysalis is ridged but smooths out in a few hours. It changes in color from jade green with gold spots to black and finally to clear before the butterfly breaks out of the chrysalis.

Here is a sequence of pictures showing the changing monarch chrysalis, from the caterpillar to the butterfly. Click images to enlarge.
