Soaring with a deliberate, fluttering flight through the tropical and subtropical forests of South America, Rothschildia speculifer (often recognized as a subspecies of Rothschildia aurota) is a magnificent giant silkmoth. As a prominent member of the Rothschildia genus, it is distinguished by its impressive size and the striking, clear, window-like patches on its wings, which lend it a unique, almost translucent beauty.
