It was a fungus that lives in the nest of a paper wasp.

它是一种生活在纸黄蜂巢中的真菌。

Scientists took paper wasps which are found on almost every continent and put them in a rectangular chamber with two colors in it.

科学家们把几乎在每个大陆都能找到的纸黄蜂放在一个有两种颜色的长方形容器里。

What's interesting here is that honeybees which have the same sized brains as paper wasps, failed this test so one takeaway was that the wasp's behavior maybe more socially complex than that of the bees.

有趣的是，与纸黄蜂大小相同的蜜蜂，没有通过这个测试，所以一个结论是黄蜂的行为可能比蜜蜂的行为更复杂。
