Here is a photographic Series of a Monarch caterpillar chrysalis transformation, a step in the life cycle of the Monarch butterfly. The caterpillar attaches to a silk pad from which it hangs. Underneath the skin, the caterpillar is transforming to the chrysalis. In these photographs the silk pad and chrysalis attachment from a previous transformation are in the foreground.
About 34 minutes transpired between the previous photograph of the caterpillar in “J” formation, attached and hanging upside down to the chrysalis. In this time the outer skin was shed, revealing the chrysalis.
