I did some searching, and apparently he's a Five-spotted Hawkmoth, aka my garden nemesis, the tomato hornworm! Never knew those hornworms grew into these adorable giant moths.

Ooooh them's fighting words. Have you tried a burger with a homegrown tomato? Pretty night and day, might just change your mind.
