Morphology
The compound names 'emperor' + 'moth' make clear that this is a type of moth associated with the epithet 'emperor', so a B1 learner who knows both words can infer it is a notable or large/majestic moth. However, specific biological details (e.g. heavily scaled, transparent wings, native range) are not predictable from the constituents alone, so the relation is only partially transparent.
Etymology
Emperor moth got its name because people thought the moth's big, showy wings and bold patterns looked like a king's cloak or crown and so seemed 'royal'. That's why the name emperor joined moth to mean a large, impressive moth type.
