What does the mouth of a Housefly do?

The mouth of a housefly is adapted for sponging and sucking, consisting of a proboscis that extends to lap up liquids. Houseflies primarily feed on decaying organic matter, nectar, and other moist substances. They use their mouthparts to break down food into a liquid form, which they can then ingest. This adaptation allows them to feed efficiently on a variety of food sources.
