Hello~
I live in Northern California (Redding –Shasta County)
I’m in need of assistance identifying this caterpillar/worm.
He looks similar to a tomato worm with the exception of his color and no horn on his rump.
My SO claims he is indeed a tomato worm but has a pinkish color because he’s been eating our purple grapes. I say no. If that was so… tomato worms would be red 😉
Please help me be right!! He hates that… 🙂

Dear Little T,
You were right to notice the similarities between your caterpillar and that of the Carolina Sphinx or Tobacco Hornworm, one of two species that feed on the leaves of the tomato, because they are in the same family.  Your caterpillar is that of an Achemon Sphinx,
Eumorpha achemon, a species that feeds on the leaves of grapes.  Caterpillars often have coloration that camouflages them while they feed, but the color is not a result of the pigment in the food.  So, you win.  Go rub it in.
