Hodges Number
Synonyms and other taxonomic changes
Heraclides rumiko Shiraiwa & Grishin, 2014. Type locality: “USA: Texas: Duval Co., Benavides, CR306, 1.8 mi west of SH339, latitude 27̊ 36'27", longitude -98̊ 26'29.4", elevation 124 m”
Explanation of Names
The species is named to honor the wife of the first author. Pronounced as ’roo(as in rue)-mee(as in meek)-koh(as in cod). The stress is on the first syllable. (1)

Eggs are laid singly on young leaves and shoots of the host plants from Rutaceae family: Zanthoxylum fagara, Ptelea trifoliata, Amyris texana, and Casimiroa greggii in Texas, or Ruta graveolens and Citrus spp. in both states, and likely others. For instance, ovipositions were recorded on Geijera parviflora in Tucson, Pima Co., Arizona (1)
It is debated as to whether this is truly a distinct species or a regional variant of P. cresphontes. There is evidence that the two may intergrade, but more study is needed on the subject.
See Also
closely allied to the now "Eastern Giant Swallowtail," the two species can usually be told apart by the shape and size of yellow spots on the neck, by the wing shape, and the details of wing patterns. (1)
