White-lined sphinx moth caterpillar (Hyles lineata) Qaurai Ruins

I was birding Qaurai Ruins (part of Salinas Pueblo Missions National Monument) recently and noticed this interesting caterpillar. I don't know a whole lot about caterpillars, but this seems to be the larvae of the widespread white-lined sphinx moth (Hyles lineata). It was a bright warm day and there were quite a few caterpillars crossing over the walkway at this really cool National Park Service site.
