𧏦動（閏尹反顧野王云䖵蟲蝡動是也蝡亦動也字書云無足而行曰𧏦動說文從虫耎聲也）。

Wriggling and squirming (𧏦動: [the first character] has the fanqie r- + [y]in [=ruǎn]; Gu Yewang says: 'This is the squirming movement of crawling insects; ruǎn (蝡) also means moving'; character books say: 'Moving without feet is called ruǎndòng (𧏦動)'; the Shuowen says it is formed with 'insect' [虫] and ruǎn [耎] as phonetic).
