Prepupal Spicebush Swallowtail Caterpillar

Hi Mike,
This is a prepupal Spicebush Swallowtail Caterpillar.  Just prior to pupation, the normally green caterpillars often change color.  If you look closely, you should be able to see a silken girdle that keeps the chrysalis upright.  Within a day, this caterpillar should metamorphose into a chrysalis.  We would love a followup photo of the chrysalis if you are able to take it.
