I was thrilled to see the Giant Swallowtail visiting my garden again. It was here, briefly, last summer. I tried to get a picture, but this thing moves very fast! I guess with wings 6" across you can really motor! Also, it needs to keep its wings moving while it feeds because otherwise it would bend the flower down. Just think of all the energy that must take.
Still not a great picture, but at least you can see the butterfly. I understand it doesn't live here, it is just passin' through.... it is established in Southern Ontario, but considered a bit rare in the Ottawa Valley. I'm honoured that it likes my garden!
