Wondering what this is? I got to page 23 and didn’t find it.

This is the caterpillar of the White Lined Sphinx or Striped Morning Sphinx, Hyles lineata, a species that is found in all 48 of the continental United States as well as Mexico and Canada. It has a highly variable caterpillar, a trait that might contribute to its range and frequency since it is so adaptable. If you scroll down the species page on the Sphingidae of the Americas website, you will find a matching example of this unusual dark variation.
