蚜虫

Sap passes right through the aphides' bodies, only getting a little thicker and sweeter.

汁液直接流过蚜虫的身, 结果只是变得更稠、更甜。

In some species, such as aphids, the flightless morph lacks wings and is called the apterous morph.

一些昆虫种类，如蚜虫，出现无翅个，为无翅型。

What with the dry weather and a plague of greenfly, my roses are very disappointing this year.

由于天气干和蚜虫灾害，今年我的长得非常令人失望。
