Manduca sexta
Giant
In parent's pepper plant
Ate an entire tomato plant!
Lori, I'd say that's a tobacco hornworm, not a tomato hornworm. They're very similar, but the tomato hornworm has 8 V-shaped markings. The tobacco hornworm just has 7 diagonal stripes, which this one has.
It's the catipillar of the Five spotted hawk moth, known also as the Tomato hornwom.

It about 2.5 maybe 3 inches. It destroyed some leaves in my dad's veggie garden!
