Here is a reference for the sphinx; http://www.butterfliesandmoths.org/species/Sphinx-kalmiae

These become quite beautiful moths! I hope you raise them, or keep a close eye on them! That would be very interesting!

The darker green one, is the Tobacco, as Eric stated, and the lighter green one is the Laurel Sphinx, characterized by the granular blue horn and the black stripe on the head.

yea i thought so..

Both species are not the Tobacco Hornworm.
