noun
paper wasp
A common name for wasps in the subfamily Polistinae, known for their long legs and papery nests.
軒下にあしながばちの巣ができた。
A paper wasp nest was built under the eaves.
あしながばちは比較的おとなしい蜂だ。
Paper wasps are relatively docile wasps.
Compound of 足長 (ashinaga, 'long-legged') + 蜂 (hachi, 'wasp, bee'). The derivation is transparent; the kanji spellings are literal descriptions.
