viceroy

This term carries a strong historical and political connotation, specifically evoking the era of colonial empires where a sovereign delegated absolute authority to a representative. It implies a hierarchical relationship where the viceroy acts as the physical embodiment of the monarch's power in a distant land, distinguishing it from a governor who might have more limited administrative duties.

In a biological context, the term is used specifically for the Limenitis archippus butterfly. The usage here is purely taxonomic and lacks the political weight of the human title, though it shares the same name due to the perceived "regal" appearance of the insect.
