What 蠐 means
蠐 names a grub in established Chinese insect terms.
Its Mandarin Pinyin spelling is qí. The Book of Songs (《詩經》), an early Chinese poetry collection, uses 蝤蠐 in a comparison for a smooth neck; Explaining Graphs and Analyzing Characters (《說文》), an early character dictionary, analyzes 蠐 as 虫 plus 齊 and explains it through 蠐螬. Natural-history and medicinal writing used these terms for insects. Sources distinguish the soil grub in 蠐螬 from the wood-boring larva in 蝤蠐, though some commentators treat the names as referring to the same kind of insect.
Specialized and literary Chinese: it appears in insect names and a classical comparison, not as a casual reaction.
On its own, it does not tell you which compound meaning is intended.

1Why does 蠐 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
