Meaning & readings

lightning-bug, firefly

On’yomi ケイ
Kun’yomi ほたる

Origin

This character combines the insect radical (mushi, meaning bug or insect) at the bottom with a sound component at the top that hints at the pronunciation. The radical tells you this character names some kind of creature, while the upper part provides a phonetic clue to how the character is pronounced in Chinese. Together they create a character specifically for the firefly, the small glowing insect that produces light on summer evenings in Japan.
