We stayed at the Marathon Inn on Grand Manan Island. One morning, when we came to breakfast, we were greeted by two Luna Moths clinging to the red front door. I was thrilled, because I had never seen a Luna Moth before. The innkeeper told us that for several years Luna Moths have appeared on that same door at about this time. They are very large, with a wingspan of 3-4.5“ and a total length of 5-6”. They only live for about a week, just long enough to mate and lay their eggs.
