Mandibles are long and curved with sharp tips for impaling a struggling victim. Mandibulate mouthparts are often used as a model to explain the evolution of mouthparts in insects due to their ancestral origin. The proboscis is similar to a sword within a scabbard. These mouthparts are used by animals to help get their food organised before they swallow it. Also the larvae of mosquito, housefly butterfly and honeybee also have biting and chewing mouthparts. Arrows show the points of articulation (condyles) with the head capsule. Most mouthparts represent modified, paired appendages, which in ancestral forms would have … The sucking functions is completed by other which are mutually alternatives and imply a clear relation between the anatomical structure, the functional properties and, finally, the feeding beha… English: The development of insect mouthparts from the primitive chewing mouthparts of a grasshopper in the centre (A), to the lapping type (B) and the siphoning type (C).
