黑脉金斑蝶在科罗拉多停留

Every year, waves of monarch butterflies migrate to south and west as colder weather arrives in parts of the United States.

每年，随着美国部分地区天气变冷，黑脉金斑蝶会成群结队地向南部和西部迁徙。

The movement generally begins in October as the butterflies make their way to Mexico and Southern California.

这场运动通常始于10月份，那时蝴蝶会飞往墨西哥和南加州。

The butterflies decided to make a pit stop and rest at John Martin Reservoir State Park on their way to Mexico.

蝴蝶决定在去墨西哥的途中在约翰·马丁水库州立公园稍作停留和休息。

"For the past couple years, Colorado Parks and Wildlife technicians have specifically planted pollinator seed mixes in plots at state wildlife areas in the Southeast Region as a response to the worldwide collapse of butterfly populations," said Bill Vogrin, Colorado Parks and Wildlife public information officer for the Southeast Region.

“在过去的几年里，科罗拉多公园和野生动物技术人员专门在东南地区的国家野生动物保护区的土地上种植授粉种子混合物，以应对世界范围内蝴蝶数量的锐减，”科罗拉多公园和东南地区野生动物公共信息官员Bill Vogrin说。

Experts at the park counted upwards of 20 species on a specific pollinator plot earlier in the week.

公园的专家们在本周早些时候统计了一个特定的授粉点上的20多种昆虫。

Unfortunately, temperatures took a dive in the region and the bulk of the butterfly migration has already moved further south.

不幸的是，该地区的气温急剧下降，大部分的蝴蝶迁徙已经进一步南移。

Monarch butterflies return to the same trees every year, which is impressive on its own, but couple that with a migration of more than 2,500 miles and that the migration spans roughly four generations, and it becomes astonishing.

黑脉金斑蝶每年都会回到同一棵树上，这本身就令人印象深刻，但再加上它们的迁徙距离超过了2500英里，而且迁徙的时间跨度约为四代，这就令人震惊了。
