i live in the west virginia area and i know that zebra swallowtail butterflies love the swampy marshy areas along the potomac river, which i live close to. does anybody have specific hotspots or areas around the potomac they know of where zebra swallowtails are very commonly seen? i love to hunt butterflies but i have only seen one zebra swallowtail in my life yet they are my favorite. thanks!
