The stages of a Gulf Fritillary Butterfly - beginning with the chrysalis which I found in our backyard attached to the garage wall.
"When the time comes for the caterpillar to create its chrysalis it turns a greyish color and begins to spin a silk-like substance into a ball on top or against a malleable surface. It then attaches its rear end to the "silk" lump and hangs upside down in a "j" position. By small contractions of the muscles it begins to shed its skin and head revealing a soft pinkish tan form. Quickly the soft form hardens and becomes greyish brown. The chrysalis stays in this form for eleven to twenty-one days." from Wikipedia.
