We have an ornamental grapevine in Carmel Valley CA. Summer temps range from 75-100. We spotted three large articulated tan/orange insects on our vines. There appear to be six or so sets of “legs@ that suspend and move the along the vine. What is it???

Dear Curious in Carmel,
This is an Achemon Sphinx Caterpillar, and though they will eat the leaves from grape and and other vines, they will not do any lasting harm to the plants.
