My aunt knows I'm into raising caterpillars so she called me to say she found one crawling on her carport. Figured it's a sphinx but which one? Have no idea what it was eating. She has ash, bouganvilla, mountain laurel, sage, rose bushes and grass around her yard. I've tried all plants that I have in my yard as well but it only nibbled on the rose bush leaves she had.

I put in a dish with dirt and it buried itself...but about an hour later it was back out crawling around. If anyone knows which species it is do let me know so I can look up it's larval host plant.

It's a light green, with the typical white streak and reddish dots. Has a slight reddish or orangish back.
