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虫，例如蚊子、马蝇、鹿虻、是有着刺吸式的口器而非舔吸式的。

With the sponging mouthpart, there’s yet another tube, this time ending in two spongy lobes that contain many finer tubes called pseudotracheae.

带有海绵状口器的还有另一个管子，这次末端是两个海绵状裂片，其中包含许多更细的管子， 称为假气管。
