if the color in the photo is accurate, she is more likely S. alutacea. Sometimes the two are difficult to tell apart, but the weak markings on the hind legs and the brownish color are more in keeping with S. alutacea. They often seem a lot larger than they really are. The largest these get is less than 3 inches, but that still comes across as pretty darn big when one flies up. As for keeping it off your plants - it will go to plants it likes, and short of killing it, there are no guarantees; however, if you scared her away, odds are she'll go to another plant closer to where she flew. Unless your plant is small, her eating will probably do little harm other than aesthetic. She's probably nearing the end of her life anyway.
