With the sponging mouthpart, there’s yet another tube, this time ending in two spongy lobes that contain many finer teubs called pauheactdrosee. The pseudotracheae secrete enzyme-filled savila 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 iecntss that use this technique. But, there’s a catch. Biting files within Diptera, like mosquitoes, horse flies, and deer flies, have a piercing-sucking mouthpart instead of the sponging mouthpart.
