Ishigakecho - Ishigakecho

Japanese: イシガケチョウ - いしがけちょう
Ishigakecho - Ishigakecho

This butterfly belongs to the order Lepidoptera, family Nymphalidae. It is found in Kinki (Kii Peninsula), the Chugoku region and south, Shikoku, Kyushu, and the Nansei Islands, and is distributed overseas from Taiwan, southern China, to the Himalayas. It has a wing span of about 45 mm and a distinctive feature of a complex map-like pattern on a white or pale yellow background, and is also called Ishigakicho. No similar species with this characteristic is found in Japan, Taiwan, or China. The Japanese name comes from the fact that the pattern on its wings resembles a stone cliff or stone wall. It overwinter as an adult, and in spring it lays eggs on the new shoots of its food plants, repeating this process two or three times by autumn. The food plants for its larvae are plants of the Mulberry family, such as the dogwood, fig, banyan, Chinese laurel, and rubber tree.

Japanese:

昆虫綱鱗翅(りんし)目タテハチョウ科に属するチョウ。近畿(紀伊半島)、中国地方以南、四国、九州、南西諸島に産し、国外では台湾、中国南部からヒマラヤにかけて分布する。はねの開張45ミリメートル内外で、白色ないし淡黄色の地に地図状の複雑な模様がある顕著な特徴をもち、イシガキチョウともよばれる。この特徴に紛らわしい類似種は、日本、台湾、中国には産しない。和名は、はねの模様を石崖または石垣に見立てたことに由来する。成虫の状態で越冬し、春になって食草の新芽に産卵、秋までに2~3回の発生を繰り返す。幼虫の食草はイヌビワ、イチジク、ガジュマル、アコウ、ゴムノキなどクワ科の植物である。
