If you had a moth beauty pageant, the luna moth would win out hands-down, in my estimation. The luna moth is one of nature’s most exquisite creations. The moth is a standout with its 3-5-inch wingspan and its beautiful, pale green wings, which extend into elongated tail extensions. 

During my lifetime I have probably only seen three adult luna moths. If you are lucky and have the opportunity to observe a luna moth, it will probably be at night. Luna moths are considered nocturnal since they are active at night. I saw my first luna moth since moving to Georgia 17  years ago, in early August on the porch of a home in Hiawassee. Unfortunately, it was barely moving and in its last stage of life. Being a former biology teacher and nature lover, I was curious and wanted to know why its life was ending abruptly.

Luna moths’ unique life cycle

1. Eggs – Luna moths lay between 200 and 400 tiny, brown-and-white-speckled eggs on the leaves of their host plants: walnut, sweetgum, hickory, persimmon, sumac and birch trees.
2. Caterpillar – The 2- to 3.5-inch larvae are bright green with a yellow line running down the complete length of their bodies. After two to three weeks of constant eating, they start to turn a reddish-orange color before creating their cocoon.
3. Pupa – The pupation stage, where they transform from a larva to an adult inside their cocoon, takes about three weeks.
4. Adult When the adult moth emerges from the cocoon, the moth pumps blood into its wings, causing them to unfurl, and it hangs upside-down while the wing veins harden in the right shape. Now it is ready to spread its wings, fly, find a mate and fulfill its life mission to produce offspring. This typically happens at night because the luna moths are nocturnal.

Unfortunately, adult moths lack mouthparts and are unable to eat, resulting in their deaths within seven to 10 days of emerging from their cocoons.

Luna moths are found throughout the eastern United States. In cooler climates, they mate once a year, but in Georgia they are active from March to September and can produce three broods of offspring per year. 

Although luna moths are large and nocturnal, they have enemies. The wings of luna moths are designed for defense against their predators. The wing pattern and color provide them with camouflage when they are resting in a tree or on leaf litter. 

On the upper mid-region of each of the four wings, there is an eyespot. The eyespot confuses a predator, allowing the luna moth time to get away or directs the attack to a less vulnerable area of the body. The elongated sections of the wings can also disrupt the echolocation ability of a bat in pursuit of its prey, as bats are enemy No. 1 for luna moths.

If you are lucky enough to find a live luna moth, try not to touch its wings. You could possibly rub off some of its powdery scales, which help it fly, regulate its body temperature and camouflage it from predators. Because it is so rare to find one of these beauties, if you do spot one it is considered a symbol of transformation and new beginnings.

Consider a spring or summer evening walk. Look on the shady side of their host trees and you might be lucky and have an opportunity to view a living luna moth.
