Konohacho (Leaf butterfly) - Konohacho (English spelling) leaf butterfly

Japanese: コノハチョウ(木の葉蝶) - コノハチョウ（英語表記）leaf butterfly

An insect of the Nymphalidae family of the Lepidoptera order (illustration). It is found in the tropics of East Asia from India eastward, with the northern limit of its distribution being the northern part of Okinawa Island. It is found locally in Okinawa, but is not uncommon on Ishigaki Island and Iriomote Island. It has a unique vertically long wing shape, and a tail-like protrusion on the hind wings, but the position and structure are different from those of the swallowtail butterfly. It is large, with a spread of about 6.5 cm, and becomes wider toward the center. The upper surface is black, orange, and indigo, with two translucent white stripes on each of the forewings. The underside resembles a dead leaf, but is highly variable, and like the shells of the clam, no two have the same pattern.

鱗翅目タテハチョウ科の昆虫（イラスト）。インド以東の東アジアの熱帯に産し，沖縄本島北部が分布の北限である。沖縄では局地的であるが，石垣島，西表島ではまれではない。縦長の特異な翅型で，後翅に尾状突起があるが，アゲハのものとは位置も構造も異なる。大型で開張は6.5cm前後，中央部に向かって幅広となる。表面は黒色，橙色，藍色の地に，前翅の半透明の白紋が各2個ある。裏面は枯葉に似ているがきわめて変異に富み，アサリの貝殻と同様，同じ模様のものは二つとない。
