culture
蠪 is a rare classical character. In 山海经 ('Classic of Mountains and Seas') it names a fox-like creature with nine tails and nine heads; old dictionaries also gloss it as a type of ant. It does not appear in modern everyday Chinese.
虫 ('insect') at the bottom is the meaning-bearing radical, historically applied to many small or strange creatures — fitting for an ant or a fabled beast.
