White-striped butterfly - White-striped butterfly

Japanese: スジグロシロチョウ - すじぐろしろちょう
White-striped butterfly - White-striped butterfly

A butterfly belonging to the order Lepidoptera and family Pieridae of the class Insecta. It is distributed from Hokkaido to Kyushu, with its southern limit being Yakushima. It is a common butterfly, but is extremely rare on Tsushima. Its wing span is about 60 mm. It resembles the common cabbage white, but can be distinguished by the dark stripes along the veins of its wings. Its Japanese name is based on this characteristic. The first generation of spring types appear in early spring, from late March to April, in the plains and low mountain areas of the Kanto region and western Japan. After that, they appear continuously until early autumn, and all but the first generation become summer types with well-developed black spots. The larvae feed on wild Brassicaceae plants, cultivated radishes, and sometimes Brassica . They overwinter as pupae.

Japanese:

昆虫綱鱗翅(りんし)目シロチョウ科に属するチョウ。北海道より九州にかけて分布し、その分布の南限は屋久島(やくしま)。普通のチョウであるが、対馬(つしま)ではきわめてまれである。はねの開張60ミリメートル内外。普通のモンシロチョウに似ているが、はねの脈に沿う暗色の条があるので見分けられる。和名はこの特徴に基づく。第1化の春型は関東地方から西日本の平地から低山地域では、早春3月下旬から4月より出現。以後、連続的に発生して初秋に及び、第1化のほかはすべて黒斑(こくはん)の発達した夏型となる。幼虫の食草は野生のアブラナ科植物、栽培されたダイコン、アブラナ類Brassicaにつくこともある。蛹(さなぎ)の状態で越冬する。
