There was a large window in my grandmother's apartment that faced out onto a heavily wooded area. I had my back to the window. My aunt noticed something on the exterior of the glass. Turning, I watched in amazement as a large green moth, freshly emerged from its cocoon, fluttered its wings. I had never seen anything like it before or since. It remained on that window, fluttering up and down against the dark backdrop, illuminated by the light inside the apartment. I later learned that it was a luna moth.
I don't know the significance, if any. I had never seen one before, nor have I ever seen one since then. Luna Moths are huge moths, with a wingspan of four and a half inches. Adult Luna Moths don't eat; in fact, they don't even have a mouth. They only live for about a week, and their only purpose is to mate.
