noun
Chinese peacock butterfly
A species of swallowtail butterfly (Papilio bianor) found in East Asia. The Japanese name literally means 'crow swallowtail', referring to its dark, iridescent wings.
カラスアゲハは羽に美しい青緑色の光沢がある。
The Chinese peacock butterfly has a beautiful blue-green sheen on its wings.
公園でカラスアゲハを見つけた。

アゲハチョウ is the general term for swallowtail butterflies, while カラスアゲハ refers specifically to the Chinese peacock species.
The name カラスアゲハ (烏揚羽) combines カラス (crow) and アゲハ (swallowtail), likely from the butterfly's dark, crow-like coloration.
