It's hard to tell from your picture but... big and green makes me think of tomato & tobacco hornworms. There's also some really beautiful months that come from BIG green caterpillars. Luna moths and Cecropia moths are a couple that come to mind. The regal moth has a caterpillar that gets almost 6 inches long. It's pretty scary looking too.
