The museum shipped in around 500,000 leafcutter ants to build a colony in the insectarium – or insect area.

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

超过 1000 年前，切叶驯化真菌。

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，到象，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.

在切叶巢内，它们是卧底：模仿蚂的标志性气味，它们在真菌花园里嬉戏和觅食，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，切叶群落覆盖数米长的地下隧道，由数百工人组， 并且可以在一夜之间将一棵树的叶落尽。
