noun
Japanese giant weevil (Sipalinus gigas)
A large weevil species native to Japan. The name is usually written in katakana as オオゾウムシ.
オオゾウムシは朽ち木の中で幼虫が育つ。
The Japanese giant weevil's larvae grow inside decaying wood.
From 大 (おお, 'big') + 象虫 (ぞうむし, 'weevil'). The exact derivation is straightforward; the kanji 象虫 literally means 'elephant bug', referring to the weevil's long snout.
