Knowra Piercing-sucking mouthparts Piercing-sucking mouthparts Feeding structures that penetrate a surface and draw out liquid through slender internal stylets. Different insect groups form these structures from modified mouthparts.
Stylet : A slender, pointed structure used to pierce material or guide liquid during feeding. Paired stylets form the piercing bundle in many insects with these mouthparts.
Insect mouthparts : The feeding structures of insects, modified across groups for biting, chewing, lapping, sucking, and other modes. Piercing-sucking designs are one specialized form of the broader insect mouthpart plan.
Mosquito : A slender-bodied fly whose females in many species feed on blood using a piercing proboscis. Its bundled stylets pierce skin while the outer labium bends back.
Chewing mouthparts : Insect feeding structures with jaws that cut and grind solid food. They process food mechanically rather than drawing liquid through stylet canals.
Food canal : A passage through which liquid food moves from a feeding site toward an animal's digestive tract. Interlocking stylets can enclose a canal that carries drawn-up liquid.
Mandible : One of an insect's paired jaws, commonly used to cut, crush, or hold food. In some piercing insects, mandibles become slender cutting stylets.
Aphid : A small sap-feeding insect that uses slender mouthparts to reach plant phloem. Its stylets navigate plant tissue to reach nutrient-rich sap.
Siphoning mouthparts : Insect feeding structures, such as a butterfly's coiled proboscis, that draw exposed liquids without piercing tissue. They suck liquid from surfaces instead of penetrating them with stylets.
Salivary canal : A passage that conducts saliva from a gland to an animal's feeding site. A second channel in some stylet bundles delivers saliva into the pierced tissue.
Maxilla : A paired insect mouthpart behind the mandibles that manipulates food and may bear sensory palps. Modified maxillae form stylets or interlocking channels in several piercing-sucking designs.
