23、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和太阳在空中的方位让黑脉金斑蝶确定它的 7 路线。最终它成功到达它过冬的地方。 4黑脉金斑蝶这一惊人的奥秘被揭开时，这一生物正处于水深火热的生存 状态中。过去的几年里，它(黑脉金斑蝶)的数量骤减了百分之九十。不幸的是， 人类活动是黑脉金斑蝶数量下降的主要原因。在黑脉金斑蝶生存的许多地方，人 们正在破坏自然环境。人们砍伐树木，他们所使用的化学制剂杀死了黑脉金斑蝶 幼虫食用的植物。 5不管怎样，对黑脉金斑蝶习性的研究让人们更多地了解了这种生物。人 们已经共同努力，记录它的迁徙，并确保它有足够的食物。如果这些努力产生效 果， 黑脉金斑蝶的数量在未来有可能再次回升。我们对这种可爱的生物了解得越 多，它生存下来并在很长一段时间内保持它在自然界中的地位的可能性就越大。
