螢
U+87A2 "螢" CJK Unified Ideograph-# is a Chinese character that traditionally refers to a firefly or glowworm, evoking the image of a luminous insect often associated with summer nights and poetic imagery in East Asian literature. Its structure combines the radical for insect or worm with a phonetic component, and in modern usage, it appears in contexts such as the Japanese word "hotaru" and the Chinese term "yinghuo chong," both meaning firefly. This character is also used in personal names and place names, carrying connotations of light, ephemeral beauty, and natural wonder across Chinese, Japanese, and Korean writing systems.
