I was wondering why the leaves of my penta plant were disappearing. Then this morning I found these “eyes” staring at me. At first I thought it was a plastic toy! What an amazing critter.

Hi Marabelle
Though it resembles a Western Tiger Swallowtail Caterpillar, your critter is a Tersa Sphinx Caterpillar.  The Swallowtail has one set of eyespots, while the Tersa Sphinx has numerous eyespots.  The Tiger Swallowtail Caterpillar does not have a caudal horn, and the Tersa Sphinx does possess a caudal horn.  Sphinx Moth caterpillars are often called Hornworms.  Penta is a typical food plant for the Tersa Sphinx Caterpillar.
