Pipevine Swallowtail (Battus philenor)

	Pipevine Swallowtail is found throughout NC, but more abundant in the mountains, where its main host is the huge, huge-leaved liana Pipevine (Isotrema macrophyllum). Carroll Co., VA 7/24/10.
	These common black butterflies are easily identified by the single C-shaped row of reddish-orange spots on the underside of the hindwing. The similar dark form Eastern Tiger Swallotail and Spicebush Swallowtail have two bands of orange spots. Clay Co., NC 5/14/05.
