A couple of years ago while I was in Nova Scotia, Canada, we stayed at a delightful bed and breakfast called the Baker’s Chest in Truro. Besides memories of the beautifully furnished house and gourmet breakfasts, the well-maintained garden had a wonderful surprise in store. The owner pointed out that a large moth had just emerged from under the decking and was drying its wings on the wooden trellis. A few hours later, there were two moths. The first had been a female and the newcomer was a male, attracted by the pheromones that she was giving out, and now the two were locked in the slow moving and elegant mating embrace that you can see in the video. They are Hyalophora cecropia, also known as the Robin Moth, and are the largest native moth in North America, with a wingspan that can reach 15 cm or 6 inches across.
