Insects in the Hemiptera order have piercing-sucking mouthparts and include bed bugs, cicadas, aphids, and leafhoppers.

半翅类的昆就具有这样刺吸的，其中包括臭、蝉、蚜、叶蝉。

The piercing-sucking mouthpart consists of a long, tube-like structure called a beak.

第二种是刺吸，由一支叫做喙的长管组成。

Still, mouthpart identification can, for the most part, help scientists—and you —categorize insects.

然而，的识别在很大程度上能够助学家——包括你——来分类昆。

The chewing mouthpart is the most common.

咀嚼是最常见的一种类型。

He's attached himself and his mouthparts have receded and merged into her, and their blood systems are now fused.

他依附在雌性安康鱼身上，已退化融入了雌性身体，血液系统也与雌性融合到一起。

There are nearly a million known insect species in the world, but most have one of just five common types of mouthparts.

世界上已知的昆物种有着数以百万种，然而多数昆都离不开五种最普遍的。

It's also the most primitive — all other mouthparts are thought to have started out looking like this one before evolving into something different.

这也是最为原始的一种类型——其它所有的都被认为是从这一种的模样进化而来的。

Biting flies within Diptera, like mosquitoes, horse flies, and deer flies, have a piercing-sucking mouthpart instead of the sponging mouthpart.

双翅目中会叮咬的昆，例如蚊子、马蝇、鹿虻、是有着刺吸的而非舔吸的。

The features of an insect's mouthparts can help identify which order it belongs to, while also providing clues about how it evolved and what it feeds on.

而昆的特征就能助我们定义它属于哪一个目，同时也能告诉我们它如何进化以及它的食物来源。

You can find this mouthpart on ants from the Hymenoptera order, grasshoppers and crickets of the Orthoptera order, dragonflies of the Odonata order, and beetles of the Coleoptera order.

这样的你可以在膜翅目的蚂蚁，直翅目的蚱蜢，蜻蜓目的蜻蜓，和鞘翅目的甲身上找到。

The juvenile stages of some insects, for example, have completely different kinds of mouths than their adult versions, like caterpillars, which use chewing mouthparts to devour leaves before metamorphosing into butterflies and moths with siphoning mouthparts.

例如许多昆的幼时期有着和成年时期完全不同的类型，比如毛在变成蝴蝶和飞蛾之前会用咀嚼来吞食叶子，而蝴蝶和飞蛾则是虹吸。
