22、迁移到另一个地方，这种一 年一度的运动叫作迁徙。它们迁徙或为了寻找食物，或为了寻找伴侣，或为了寻 找更温暖的天气。北美黑脉金斑蝶的迁徙是大自然中最为美妙的迁徙之一。 2每年秋天，数百万只黑脉金斑蝶会开始一段漫长而艰难的旅程。这些漂 亮的昆虫翅膀上有着漂亮的黑色和橙色斑纹。不知怎么地，它们设法向南飞行大 约 4 000 千米，前往加利福尼亚或墨西哥。但一直到最近，也没有人知道它们是 如何做到的。 3 华盛顿大学伊莱 席里哲曼(Eli Shlizerman)教授领导的科学家(研究)小组现 在已经找到了答案。他们发现黑脉金斑蝶可以分辨出一天的时刻。它用眼睛来测 量太阳的方位。 这两条信息一天中的时刻
