About
The character 蝣 is a phono-semantic compound created for biological nomenclature, specifically for a short-lived insect. Its structure combines the insect radical 虫 on the left, indicating its semantic category, with the phonetic component 斿 (yóu) on the right, providing the sound. 蝣 appears only in the compound 蜉蝣, the Chinese term for mayfly. Due to the mayfly's famously brief adult lifespan, this character is often used in classical poetry and philosophical texts as a symbol of life's transience, the swift passage of time, and human insignificance against the universe.
