Ugly thing. I hope that you kept it from reproducing. I lucked out this year. I had NO hornworms on my tomatoes. Unlike last year. :-(Lou
Our last garden was overrun with these. I never understood how they could be so damn huge, and impossible to see at the same time. I learned instead to look for the frass they leave behind. Maybe you need some turkeys...they love them! I'd suggest chickens, but I think they'd choke on them :P
