While watering my River Birch tonight, I jumped out of my skin when I saw this guy. Can you see him in the picture? He was SO big, I almost put a leash on him and took him for a walk. He really is beautiful - kind of translucent green, about 2 inches long and as think as a ball park frank! At first I thought he might be one of those tomato horn worm, but no horns and way bigger then I've seen before.

Any ideas if he's a good guy or a bad guy?
