Great Ash Sphinx

@ ForestDragon, Thank You ! :)

Just doing a search on "Tomato Hornworm" and came across your beautiful spotting. Because of your detailed images I was able to match your caterpillar with the larva of a Great Ash Sphinx.

Many Sphinx caterpillars look very similar. Your caterpillar has distinctive markings and coloration that distinguish it from it's cousin, Manduca quinquemaculata.

Please note the pale stripes on the head, tomato Hornworms don't have these.

Your caterpillar has seven long diagonal on the side, Tomato Hornworms have eight V-shaped stripes on the side:

There are some other differences. Just take a look through the images and compare. See what you think!

@ textless, Thank you !

Excellent photo series!

@ HeatherMiller! Thank you !

This looks like a rolled up leaf - what great eyesight to spot this. Great camouflage.

@ S Frazier, Thank you! :)

@ CourtneyVerk, Thank you ! :)

Moved to Arthropods for you.

@ avatb and annorion ! Thank you both for your comments and ID suggestions !

7 diagonal line is Tobacco Hornworm. Spotting with good discussion of differences: http://www.projectnoah.org/spottings/711...

It turns into the Five-Spotted Hawkmoth. I think that's what you have, anyway.
