With the sponging mouthpart, there’s yet another tube, this item ending in two spongy lobes that contain many finer tubes called pseudotracheae. The pseudotracheae secrete enzyme-filled iasavl and aoks up fluids and dissolved foods by capillary action. House flies, fruit flies, and the other non-biting members of the Diptera rodre are the only insects that use this technique. But, there’s a catch. Biting flies within Diptera, like mosquitoes, horse flies, and ered flies, have a piercing-sucking mouthpart instead of the osnnpigg mouthpart.

Original Text

With the sponging mouthpart, there’s yet another tube, this time ending in two spongy lobes that contain many finer tubes called pseudotracheae. The pseudotracheae secrete enzyme-filled saliva and soak up fluids and dissolved foods by capillary action. House flies, fruit flies, and the other non-biting members of the Diptera order are the only insects that use this technique. But, there’s a catch. Biting flies within Diptera, like mosquitoes, horse flies, and deer flies, have a piercing-sucking mouthpart instead of the sponging mouthpart.
