Conclusion.
After comparison of the different mouthparts of diptera class of insects, it is assumed that the different species have evolved their mouthparts to suit their feeding habits. The change in feeding habits is due to the competition for food source thus making them to evolve mouthparts that can suit them to the type of environment they live in. For example, the Tsetse fly is only known to be found in the African continent where the population of animals is high. This has evolved them to develop well-formed proboscis that can help to draw blood from their hosts. Housefly is found everywhere due to the abundance of food source in liquid form. This have helped them to maintain their sponging mouthparts. In any competitive environment where food is scarce, horsefly has a comparative advantage than any other blood sucking diptera as it also have sharp mandibles and maxillae that can bite and cut through the skin of the hosts. It also have longer proboscis in male to reach deep into the nectar of flowers.
