Hemiptera (Rhynchota: Plant Bugs, Etc.)

摘要: Two pairs of wings usually present; the anterior pair most often harder consistency than posterior pair, either uniformly so (Homoptera) or with apical portion more membranous remainder (Heteroptera). Mouthparts piercing and suctorial, palps atrophied; labium forming a dorsally grooved sheath in which lie two bristle-like stylets modified mandibles maxillae). Metamorphosis gradual, rarely complete.
