Found both the normal green hornworm and the almost black one on 8/17/14 just 3 miles south of the Village of Lake Ann, Michigan. zip code 49643.
The darker one was much more aggresive, vibrated and emitted an odd noise when handled even slightly.
Found a total of 4 that year.

Dark Tomato Hornworm and Tobacco Hornworm
Dear Bryan,
Though they were both probably feeding on Tomato Plants, your two Hornworms represent different species in the same genus. The dark Hornworm is a dark morph of a Tomato Hornworm, Manduca quinquemaculatus, and the green Hornworm is a Tobacco Hornworm, Manduca sexta. It is very curious that the Tomato Hornworm was the more aggressive of the two.
