Tiger Swallowtail Caterpillar

Tiger Swallowtail Caterpillar

Dear bug finder,
You have found the caterpillar of a Tiger Swallowtail, Papilio glaucus.  BugGuide has an image of this typically green caterpillar with the same coloration as yours, and there is a comment that judging by the color, it is ready to pupate.
BugGuide also indicates:  “Caterpillars feed on Sweet Bay (Magnolia virginiana), Black Cherry (Prunus serotina), Swamp Bay(Persea palustris) and Tuliptree (Liriodendron tulipifera). Adults take nectar from a variety of flowers.“  The adult butterfly is typically a large showing yellow tailed butterfly with black stripes, though there are some dark females.
