U+87D4 "蟔" CJK Unified Ideograph-# Unicode Character

U+87D4 "蟔" CJK Unified Ideograph-# is a rarely used Chinese character classified under the radical for insects or worms. Its primary meaning is obscure, though historical dictionaries like the Kangxi Zidian record it as referring to a type of mythical worm or insect, specifically one said to be born from decay or to transform into a moth. The character is composed of the insect radical on the left and the phonetic component "黑" (hei, meaning black) on the right, suggesting a possible association with dark-colored or hidden creatures. In modern usage, it is extremely uncommon and appears mainly in specialized philological contexts rather than everyday Chinese writing.
