We found this caterpillar in the garage in southern utah in September. Its green and purple banded with a green tail.
According to Bill Oehlke’s website Sphingidae of the Americas, the caterpillar of the Waved Sphinx, Ceratomia undulosa, changes color: “Just prior to pupation, larvae frequently take on a rosy hue.” Sphinx Moth caterpillars are often called Hornworms because of the prominent caudal horn found on the caterpillar of many species, including the Waved Sphinx.
