螘穴（上冝倚反爾雅曰蚍蜉大螘小者螘郭注云大者俗呼馬蚍蜉說文從虫豈聲也經文作蟻[義/虫]皆俗字也）。

螘穴 [anthill / ant burrow] (The upper character is pronounced with the fanqie 冝倚 [yǐ]. The Erya says: “The pīfóu is a large ant; small ones are called 螘.” Guo [Pu]'s commentary says: “Large ones are popularly called horse pīfóu.” The Shuowen jiezi says: “Formed from 虫 [insect] with 豈 as the phonetic element.” The sūtra text writes it as 蟻 or [義/虫], which are both popular characters).
