Euproctis subflava (poisonous moth)

Japanese: ドクガ(毒蛾) - ドクガ（英語表記）Euproctis subflava

An insect of the Lepidoptera order, family Lymantriidae (illustration). Wing span is about 3cm in males and about 4cm in females. It is orange-yellow, with two pale lines on the forewings, with the area between them being slightly black. It often has one or two black markings on the outer line. Its antennae are comb-like, but the females have shorter antennae. It is found from Hokkaido to Kyushu, Tsushima, the Korean Peninsula, southeastern Siberia, and China. Adults appear in the summer and often fly to lights. When a female bumps into a wall or a lamp shade, the scales on the tail tip fly off, taking with them the poisonous setae from the larvae's stage. If they pierce the skin, it can cause itching and inflammation.

鱗翅目ドクガ科の昆虫（イラスト）。翅の開張は雄3cm内外，雌4cm内外。橙黄色で，前翅には2本の淡色線があり，その間は多少黒みを帯びる。外線部に1～2個の黒紋をもつことが多い。触角は櫛歯（くしば）状だが，雌では櫛歯が短い。北海道から九州，対馬，朝鮮半島，シベリア南東部，中国に分布する。成虫は夏に出現し，よく灯火に飛来する。雌が壁や電灯の笠などにぶつかって，尾端の鱗毛が飛び散ると，そこに付着していた幼虫時の毒針毛がいっしょに散り，皮膚に刺さると，かゆみや炎症が起こる。
