蝡動（上潤尹反字統云蝡蝡蟲動貌也有足曰蟲無足曰蝡廣雅作𧔀或作[北/穴/瓦]說文動也從虫耎聲）。

蝡動 (the upper character has the fanqie 潤尹. The Zitong says: '蝡蝡 denotes the wriggling appearance of insects. Those with legs are called 蟲 (insects); those without legs are called 蝡 (wriggling worms).' The Guangya writes 𧔀 or [北/穴/瓦]. The Shuowen says: 'To move.' It is formed from [the semantic component] 虫 (insect) and 耎 as the phonetic component).
