黑脈金斑蝶在科羅拉多停留

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

每年，隨著美國部分地區(qū)天氣變冷，黑脈金斑蝶會成群結(jié)隊(duì)地向南部和西部遷徙。

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

這場運(yùn)動通常始于10月份，那時蝴蝶會飛往墨西哥和南加州。

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

蝴蝶決定在去墨西哥的途中在約翰·馬丁水庫州立公園稍作停留和休息。

"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.

“在過去的幾年里，科羅拉多公園和野生動物技術(shù)人員專門在東南地區(qū)的國家野生動物保護(hù)區(qū)的土地上種植授粉種子混合物，以應(yīng)對世界范圍內(nèi)蝴蝶數(shù)量的銳減，”科羅拉多公園和東南地區(qū)野生動物公共信息官員Bill Vogrin說。

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

公園的專家們在本周早些時候統(tǒng)計了一個特定的授粉點(diǎn)上的20多種昆蟲。

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

不幸的是，該地區(qū)的氣溫急劇下降，大部分的蝴蝶遷徙已經(jīng)進(jìn)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.

黑脈金斑蝶每年都會回到同一棵樹上，這本身就令人印象深刻，但再加上它們的遷徙距離超過了2500英里，而且遷徙的時間跨度約為四代，這就令人震驚了。
