What type of mouthparts do house flies possess?

House flies possess sponging mouthparts, which are specially adapted to their feeding habits. These mouthparts consist of a long, flexible structure known as a proboscis, which ends in flattened pads that can absorb liquid. House flies feed by regurgitating digestive enzymes onto solid food or liquid, which breaks it down before they sponge it up. This method allows them to effectively consume a variety of substances, including decaying organic matter.

The sponging mechanism is unique to certain fly species, including house flies, setting them apart from other insects that may have different feeding mechanisms, such as chewing or sucking. This adaptation plays a crucial role in their ecological niche, particularly in the decomposition process and nutrient recycling.
