Nomion

No mythological origin story for a supernatural Nomion is present in the provided sources. Instead, the attested usages show three distinct contexts: (1) Linnaean-style taxonomic epithets used in the scientific names of butterflies (for example Parnassius nomion and Hypomyrina nomion), where 'Nomion' functions as a Latinized species or subspecies name without folkloric narrative; (2) modern proper-name usages in popular culture and fandom (for example character or title instances on Battlestar Wiki and contemporary web content), which are secular name usages rather than traditional origin myths; and (3) a single Wikidata label that reads 'ruler in Caria in Greek mythology' (Wikidata Q16330774). The Wikidata label is uncited in the supplied materials and is not supported by any primary mythographic source provided here, so it should be treated as an unstable database annotation rather than an attested origin story.

There is no description of a supernatural appearance for a being named Nomion in the available sources. What is described are actual butterflies bearing the epithet: Parnassius nomion (the Nomion Apollo) is identified as a forest-steppe butterfly in the snow-Apollo genus Parnassius (family Papilionidae) found across parts of Eurasia, and Hypomyrina nomion (the dark orange playboy) is a Lycaenid butterfly found across parts of West and Central Africa. Modern proper-name occurrences (e.g., 'Stu Nomion' or 'Nomion's 3rd Sonata') are titles or personal names and include no physical or anthropomorphic description of a supernatural entity.

No powers, supernatural abilities, behaviors, or interactions are attributed to a Nomion in the supplied sources. The only behaviors implied relate to the biological existence and geographic distribution of the butterflies named with the epithet; however, specific behavioral ecology (e.g., feeding, flight patterns) is not provided in the excerpts. No rituals, interactions with humans, or cosmological roles for a supernatural Nomion are documented in the available material.
