Hemaris thysbe

tags: animals, hummingbirds, insects, biology, streaming video This is a lesson in observation. This is a North American animal. I know what this is (and I knew as soon as I saw the still image on the video) but I am asking you: what is this; hummingbird or insect? And for a bonus, can you tell me the species? This is a Common Clearwing, also known as the Hummingbird Clearwing Moth, Hemaris thysbe.
