Papilio glaucus (Eastern Tiger Swallowtail, male)
It was a bit late in the day before I went out to take pictures so the light was a bit low. I didn’t take a tripod but the problem was more with the subject moving than anything else. Butterflies don’t often sit still when they are feeding. I managed to get reasonably close to this tiger swallowtail but his wings were fluttering and he was moving about the whole time. I also saw a sphinx moth (most likely genus Hemaris) but the pictures of that are too blurry to be worth much.
