White Lined Sphinx Caterpillar

What is this?
Hi there,
I’m attaching a photo of what I would think is a hornworm, but I haven’t found any photos anywhere of this caterpillar. They showed up 3 days ago, overnight, and they are everywhere! In the garden, the driveway, the lawn, backyard… they are even climbing the stucco walls of my home. Help! I’ve been scooping them into 5 gallon buckets… what else can I do? I live in Sedona, Az. Thanks,

Hi Norma,
There are at least three distinct color variations of the White Lined Sphinx Caterpillar, Hyles lineata, and this is one of them.
