Found within 2 feet of the lake, definitely not a domestic escapee. The 630 acre domain has been in private hands for approximately 80 years, and the lake which is a quarter-mile above an old farming area has never seen domesticate planting of this sort.

Only the second time that I have seen this insect. The other time was also in the same location a few years ago. That specimen was fully 5 inches or more in width. This one is around 3 inches. Two IDs as a Luna Moth.
