Caught on camera! A Monarch larvae turning to attach itself securely to its silk button.

Be sure not to disturb the monarchs when they are preparing to molt to the pupal, or chrysalis, stage.

Just before they pupate, monarch larvae will spin a small silk button, or pad. The larvae will then hang upside down from this pad by their last pair of prolegs, assuming the J-shaped position of the prepupa. The silk comes from the spinneret on the bottom of the head. As it sheds its skin for the last time, the caterpillar stabs a stem into the silk pad to hang. This stem extends from its rear end and is called the cremaster.
