Mating moths

Thank you Katharine Staiger for this photo of mating Sphinx moths (Smerinthus ophthaimica) found on a peony in their garden. This is likely one of the largest moths that can be found in the Cowichan Valley. I am guessing the large one is the female, measuring about two inches.  The hind wings, which have the striking eye spots are not opened here.  I guess they were not trying to attract attention.  Gail
