Clusters of tiny insects called aphides were to be found on the underside of the leaves.

结果在树叶背面找到成串叫作蚜虫小虫子。

After this interval, I felt sure that the aphides would want to excrete.

这段时间过后， 我确信蚜虫会想要排泄。

The aphis is known as the ant's cow, and school children are taught to be intrigued by the conception.

蚂蚁被称为蚂蚁牛， 学童被教导对这个概念很感兴趣。

Even the quite young aphides behaved in this manner, showing that the action was instinctive, and not the result of experience.

非常年轻蚜虫也有这种行为， 表明这种行为本能， 而不经验结果。

I removed all the ants from a group of about a dozen aphides on a dock-plant, and prevented their attendance during several hours.

我从一个码头植物上二只蚜虫群中清除了所有蚂蚁， 并在几个小时内阻止了它们出现。

Examination shows the under side of the leaves a mass of small green aphis, or plant lice, sucking the sustenance of the leaves and so of the tree.

检查发现叶子下面有一团小绿色蚜虫，或植物虱子，吸食树叶和树营养。

Oddly, for all their sweet tooth and their innocent love of aphis milk and lettuce seed, ants are fiercely carnivorous. It is meat for which they would tear you limb from limb.

奇怪，尽管蚂蚁喜欢吃甜食，对蚜虫奶和生菜种子天真无邪，但它们却凶猛食肉动物。这他们会把你撕成碎片肉。

It is certain, from the observations of Huber, that the aphides show no dislike to the ants: if the latter be not present they are at last compelled to eject their excretion.

根据 Huber 观察， 可以肯定， 蚜虫对蚂蚁并没有表现出厌恶：如果没有蚂蚁，它们最终将被迫排出排泄物。

But as the excretion is extremely viscid, it is no doubt a convenience to the aphides to have it removed; therefore probably they do not excrete solely for the good of the ants.

但由于排泄物非常粘稠， 将其清除无疑为了方便蚜虫；因此，它们可能不仅仅为了蚂蚁利益而排泄。

In Switzerland the slaves and masters work together, making and bringing materials for the nest: both, but chiefly the slaves, tend and milk as it may be called, their aphides; and thus both collect food for the community.

在瑞士，奴隶和主人一起工作， 为巢穴制作和运送材料：双方，但主要奴隶， 照管和挤奶， 可以称之为他们蚜虫；因此，他们都为社区收集食物。
