An insect of the Hemiptera family, Bucconidae (illustration). It is so named because the male protects the eggs laid on its back until they hatch. It is a brown, flat, egg-shaped aquatic stink bug with a body length of about 19 mm. It has a short, large proboscis. Its front legs are powerful prehensile legs with two small claws at the tips, and its middle and back legs are swimming legs. It has a pair of retractable breathing valves at the tip of its abdomen, which it uses to take in air when floating on the water's surface. It is widely distributed in Honshu, Shikoku, Kyushu, Korea, and China, but its habitat is shrinking due to water pollution. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
半翅目コオイムシ科の昆虫(イラスト)。背に産み落とされた卵を孵化(ふか)するまで,雄が保護する性質があるのでこの名がある。褐色をした平たい卵形の水生カメムシで,体長は19mm前後である。口吻(こうふん)は短くて大きい。前脚は強大な捕獲脚で先端に小さな2個のつめをもち,中・後脚は遊泳脚になっている。腹端に出し入れできる1対の呼吸弁がつき,水面に浮かんでいるとき,そこから空気を取り入れる。本州,四国,九州,韓国,中国に広く分布するが,水が汚染されてきているため,生息地は狭くなっている。
