I’ll often try to get shots of butterflies with their wings wide open, but when they turn sideward, you can sometimes get an equally spectacular view of them slowly sipping nectar. I can’t identify the flower, but the butterfly definitely is an Eastern Tiger Swallowtail (Papilio glaucus) that I chased about this past weekend at Green Spring Gardens.
