This lime green visitor is a luna moth (Actias luna), probably one of the most spectacular moths of North America. At almost a 4 1/2″ wing span, it’s hard to miss. We left the deck light on last night and these moths are attracted to light. I consider that light pollution and we won’t do that again.
On the fore wing and hind wings, it has eyspots to fool predators but I find a lot of wings on my walks so not everyone is fooled. The adult moth lives for about a week after emerging from the cocoon when mating and laying of about 200 eggs occurs. The moths have no mouth parts at this stage and eat nothing for this week.
