This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
蚸 combines 虫 (insect) with 斥, but the exact historical development and original meaning are uncertain.
The insect radical 虫 beside 斥 suggests a creature, but without a clear meaning, picture a rare bug that is hard to identify.
For レキ, imagine a rare insect that makes a clicking sound: 'reki' echoes the noise of its tiny legs.
