These dark fleshy caterpillars attach like other swallowtails with their rear cremaster hooked into a pad of silk. They make the same silk thread sling for their mid-section. They curl their head down and tuck their six feet in toward their body. Soon their outer skin changes to a dark chrysalis that looks like a dead leaf.
There are many hanging on the shrubs and twigs near by the host plant White-veined Pipevine, A. fimbriata.
