Tobacco Hornworm

I found this little guy munching away at the leaves of my tomato plant -- I've noticed little holes appearing in the leaves and have diligently been checking for caterpillars regulary, picking them off and flicking them away or feeding them to ants whenever I find some (they're usually about 1/4" long). Recently, though, I've noticed entire leaves missing and suspected there must be a caterpillar that has been eluding me. Sure enough, near a stem that has had all its leaves eaten off of it, I found this Tobacco Hornworm. Easily confused with a Tomato Hornworm, the Tobacco Hornworm "horn" is red, while a Tomato Hornworm's is black.
