aphides

Clusters of tiny insects called aphides were to be found on the underside of the leaves.
Sap passes right through the aphides' bodies, only getting a little thicker and sweeter.
汁液直接流过蚜虫的身体，结果只是变得更稠、更甜。
I bound the base of the tree with sticky tape , making it impossible for the anTS to reach the aphides.
我用一条胶带把桃树底部包上，不让蚂蚁接近蚜虫。
Aphides are like cows in ants' world, so they are called "ant's cow" .
蚜虫就是蚂蚁世界的奶牛呀，所以也叫“蚁牛”。
