Looks like a hawkmoth to us but has a black tail (not red).
What’s your thought?

Probably Whitelined Sphinx Caterpillar

Probably Whitelined Sphinx Caterpillar

Dear Fetters family.
You are correct that this is the caterpillar of a Hawkmoth or Sphinx in the family Sphingidae, and we can immediately narrow it down to a member of the genus
Hyles.  According to the Sphingidae of the Americas website, there are three members of the genus that are found in Washington, Hyles euphorbiae, Hyles gallii and Hyles lineata, and all three have highly variable larvae.  We believe this is the caterpillar of a Whitelined Sphinx, based on this image posted to BugGuide.
