I think it's a variety of fall army worm.

Sorie, How long is it? To me, it looks a little too long to be an army worm. They generally max out at about 1.5" at the most. Also, the army worms I see here aren't shiny like that--they have a matte appearance. I guess an army worm could be shiny if it was wet though.

When you look at either end of the worm, do you see a little thorn-like horn? I've had brown hornworms that look very similar to the cat in your photo, although I've never noticed they were particularly shiny either.

Not sure I can find it again but will check. Thanks

He's gone now. But he was about 3" long. Was slimy looking, Sorry not much help.
