A species of swallowtail butterfly (Papilio bianor) found in East Asia. The Japanese name literally means 'crow swallowtail', referring to its dark, iridescent wings.
The Chinese peacock butterfly has a beautiful blue-green sheen on its wings.

Katakana spelling is common for this butterfly name.
Kanji spelling is rarely used; the word is usually written in kana.
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.
