1.
mayfly; dayfly; ephemera
A delicate winged insect of the order Ephemeroptera, known for its extremely short adult lifespan of only a few hours to a few days. A classic symbol of transience and the fleeting nature of life in Japanese literature.
The kanji 蜻蛉 can also be read as とんぼ (dragonfly), but the reading かげろう specifically refers to the mayfly. This is an example of a kanji compound with two entirely different meanings depending on the reading.
The mayfly is a powerful literary symbol of impermanence (無常) in Japanese culture. The classical work 蜻蛉日記 (The Gossamer Diary, c. 974) takes its title from the insect, likening the author's uncertain existence to a mayfly's fleeting life.
Not to be confused with the homophone 陽炎 (heat shimmer), which uses different kanji and has a completely different meaning.
