2- Eurytides marcellus(Zebra Swallowtail)
- Eurytides philolaus(Dark Kite-Swallowtail)
Eurytides is a of swallowtail butterflies in the Papilionidae, distributed across North, Central, and South America. Members are commonly known as kite swallowtails due to their angular, sail-like wing shape. The genus contains approximately 20 organized into four subgenera: Eurytides, Bellerographium, Neographium, and Boreographium. One well-known member, Eurytides marcellus (zebra swallowtail), was historically placed in this genus but has been reassigned to other genera in some classifications. The genus exhibits considerable diversity in wing pattern, ranging from boldly striped black-and-white forms to species with yellow, blue, or green coloration.

Distribution
Found from North America through Central America to South America. occur across a broad latitudinal range, from the eastern United States (e.g., Eurytides marcellus in the eastern USA and Canada) to northern South America (e.g., Eurytides asius). Specific distribution varies by species: Eurytides philolaus ranges from Texas and northern Mexico to Colombia and Venezuela; Eurytides epidaus occurs in Mexico (Yucatán) and Honduras; Eurytides zonaria is restricted to Hispaniola; Eurytides celadon occurs in Cuba and Isla de la Juventud; Eurytides marcellinus is to Jamaica.
Similar Taxa
- MimoidesSome Eurytides have been moved to Mimoides; both genera share the kite swallowtail wing and were historically confused, requiring careful examination of genitalic and wing venation characters for separation.
- ProtographiumClosely related within the same tribe Leptocircini; in both genera have tailed hindwings and angular wing margins, but differ in specific wing pattern elements and male genitalia structure.

Subgeneric classification
The is divided into four subgenera based on phylogenetic and morphological studies: Bellerographium (containing E. bellerophon), Eurytides (containing E. salvini, E. columbus, E. orabilis, E. serville, E. callias, E. dolicaon, and E. iphitas), Neographium (containing the majority of including E. philolaus, E. agesilaus, and E. epidaus), and Boreographium (containing E. marcellus, though this species has been transferred to other genera in some treatments).
Hybrid origin
Eurytides × oberthueri from Mexico and Honduras is considered a natural hybrid between E. agesilaus and E. philolaus, demonstrating that reproductive isolation between some is incomplete.
