Where do monarch caterpillars make their crysalis?

Monarch caterpillars typically make their chrysalises on the undersides of leaves or in sheltered locations like stems, branches, or fences. They often choose spots that offer some protection from predators and harsh weather. After attaching themselves with a silk thread, they undergo transformation into a chrysalis, which is usually green with gold accents. This process usually takes about 10 days to two weeks before they emerge as adult butterflies.
