While visiting Saco Heath last week with my friend Stef, we were treated to this Tiger Swallowtail feeding on the Sheep Laurel next to the Atlantic Cedar grove at the end of the boardwalk. I am still not sure how to distinguish Canada from Eastern, though the Colby College butterfly list has Eastern only as a “Rare Stray” in Maine. The safe bet then is Canada Tiger Swallowtail. The real zone of overlap seems to be in Northern Massachusetts…which is not so far south of us as the crow flies. 🙂 Sony RX10iv at 600mm optical and 2x Clear Image Zoom for 1200mm equivalent.
