Knowra Hemiptera Hemiptera Hemiptera is an insect order whose members typically feed using piercing-sucking mouthparts. It includes true bugs, aphids, cicadas, leafhoppers, and scale insects.
Hemipteran mouthparts : A beak-like feeding apparatus of interlocking stylets that pierce tissues and draw fluids. These specialized stylets distinguish the order’s characteristic feeding method.
Aphid : A small sap-feeding insect in the superfamily Aphidoidea, often reproducing rapidly on plants. Aphids are prominent crop pests and vectors of plant viruses.
Periodical cicada : A cicada species in Magicicada whose broods emerge synchronously after 13 or 17 years underground. Its mass emergence is an unusually conspicuous hemipteran life-history strategy.
Homoptera : A former insect grouping that combined hemipterans such as cicadas, aphids, and leafhoppers. Modern classifications reject it as a natural group because it excludes true bugs.
Auchenorrhyncha : A hemipteran group containing cicadas, leafhoppers, planthoppers, and spittlebugs. This lineage includes many familiar jumping and sound-producing sap feeders.
Asian citrus psyllid : A sap-feeding insect that transmits the bacterium responsible for citrus greening disease. It illustrates how a hemipteran can spread a devastating plant pathogen.
Brood X : A large eastern North American brood of 17-year periodical cicadas that emerged in 2021. This named emergence shows how synchronized cicada generations become ecological events.
Thysanoptera : An insect order containing thrips, many of which feed by rasping plant tissue and sucking its contents. Thrips also feed on plant fluids but belong to a separate insect order.
Sternorrhyncha : A hemipteran group that includes aphids, whiteflies, psyllids, and scale insects. Its members include several small, often plant-colonizing lineages.
Bed bug : A blood-feeding insect, especially Cimex lectularius, that lives near human sleeping places. This blood-feeding true bug shows that not all hemipterans feed on plants.
