The first involved is our soon-to-be queen leafcutter ant.

第一个涉及的是我们即将成为后的切叶。

More than 10 million years ago, leafcutter ants domesticated fungus.

超过 1000 年前，切叶驯化了真菌。

So that's anywhere from the elephants down to the leafcutter ants and all the little reptiles and all the little frogs.

这意味着，大到大象，小到南美切叶以及各种小爬虫和各种小青蛙。

Inside the leafcutter nest, they're undercover: closely mimicking the ants' signature scent, they frolic and feed in the fungal gardens, mostly undetected.

切叶巢内，它们是卧底：模仿蚂的标志性气味，它们真菌花园里嬉戏和觅食，大部分时间未被发现。

Eventually, the leafcutter colony covers several meters of underground tunnels, comprises millions of workers, and can defoliate a tree in a single night.

最终，切叶群落覆盖了数米长的地下隧道，由数百工人组成， 并且可以一夜之间将一棵树的叶落尽。
