From our front porch in the Town of Maine on Saturday 7 June 2008. Luna moths are one of the most unusual and beautiful of the North American moths known as Saturnidae. They are well known for their green-yellow colors and long tails,and although they are often seen in pictures, they are a real surprise when found in nature. Although they are common throughout the eastern U.S., their night flying habits and short life span as an adult moth, only about 1 week, combine to make them a rare find. The luna moth, with a wingspan of 4.5-5.0 inches, is one of the largest moths in North America and is very common in many of the eastern states from Maine all the way to Florida.
