U+87D0 "蟐" CJK Unified Ideograph-# Unicode Character

U+87D0 "蟐" CJK Unified Ideograph-# is a Chinese ideograph that is not commonly used in modern standard Mandarin or Japanese, but it does appear in some historical or specialized contexts. Its structure combines the radical for "insect" or "worm" (虫) with a phonetic component, though its precise meaning and usage are obscure and not well documented in major dictionaries. In Japanese, it is sometimes associated with the reading "semi" (as in cicada) or found in rare personal or place names, but it lacks a clear standardized definition. Overall, this character is considered a rare or variant glyph within the CJK (Chinese, Japanese, Korean) unified ideograph block, with limited practical application in contemporary writing systems.
