Which group of insects has sucking mouthparts?

Explanation:
Sucking mouthparts are specialized for piercing plant tissue and drawing fluids. Aphids, scale insects, and leafhoppers feed by inserting needle-like stylets into plant tissues to suck sap, a clear example of this feeding adaptation. The other groups rely on chewing or grinding mouthparts (caterpillars, many beetles, maggot-like larvae, or leaf-miner adults), which are built for biting and chewing rather than extracting sap. So the mix that best fits sucking mouthparts is the aphids, scale insects, and leafhoppers.
