I was wondering what kind of caterpillar this is? What will it turn into? I found it in the grass, what do I feed it?

Bedstraw Hawkmoth Caterpillar

Hi Carol,
In trying to correctly identify your Hornworm, we have also made a correction to our archives.  Many years ago we received a photo of a caterpillar with identical markings from Montana, and at that time, we narrowed the possibilities to two species in the same genus, the White Lined Sphinx and the Bedstraw Hawkmoth.  At that time the Sphingidae of the Americas did not have an image of a Bedstraw Hawkmoth Caterpillar,
Hyles gallii, with this particular color variation, but now it does.  We suspect this is the prepupal coloration since many caterpillars change colors just prior to metamorphosis.
