What 螶 means
It has a mayfly reading and a separate old animal-name reading.
In Mandarin Pinyin, qú and jù begin with similar soft ch sounds: qú has a stronger puff of air, while jù has less. Both use an ee-like vowel with rounded lips. qú is the mayfly reading, with rising pitch; jù is the old animal-name reading, with falling pitch.
The Eastern Han dictionary Shuowen Jiezi—a Chinese character dictionary completed around 100 CE—analyzes 螶 as 䖵 plus 巨: 䖵 marks an insect-related class, while 巨 gives a sound clue.
Why do 蜉蝣 and 渠略 appear with 螶?
They belong to its mayfly naming history.
Classical commentary links the mayfly name 蜉蝣 with 渠略. The insect's short life also became a literary image of impermanence; that association belongs to the mayfly tradition, not a separate modern meaning for 螶.
