Cimicoidea

Family Guides

5

Cimicoidea is a superfamily of true bugs (Hemiptera: Heteroptera: Cimicomorpha) characterized by a modified into a straw-like rostrum used for feeding on animal or prey. The superfamily includes diverse with contrasting ecologies, ranging from (Cimicidae, Polyctenidae) to plant-feeding (Lyctocoridae). Evolutionary studies indicate correlated evolution between selection and morphological traits, with transitions to live plants coinciding with angiosperm radiation in the mid-Cretaceous.

Habitat

vary substantially across constituent . Polyctenidae occupy caves and underground sites associated with bat roosts. Lyctocoridae inhabit live plants, with some species found near sap-exuding parts on tree trunks. Dead plant habitats have been correlated with in certain lineages. The superfamily spans diverse ecological settings from subterranean to arboreal environments.

Distribution

Global distribution encompassing multiple biogeographic regions. Polyctenidae occur in both Eastern Hemisphere (Africa, Asia, Australia) and Western Hemisphere (North and South America). Specific records include: Turkey (Southeastern Anatolia region), Japan (Shikoku and Kyushu), Kenya, South Africa, Rwanda, and other Afrotropical localities.

Diet

Highly variable across . Polyctenidae are of bats. Cimicidae are hematophagous on birds and mammals including humans. Lyctocoridae feed on plant exudates, specifically documented feeding on exuded sap of Sawtooth Oak (Quercus acutissima). Other families include predatory .

Host Associations

Life Cycle

Polyctenidae exhibit viviparity with the entire completed on bat ; nymphs are dorsoventrally flattened, eyeless, and wingless. Cimicidae are , depositing on substrates near hosts. Reproductive strategies vary substantially across .

Behavior

Polyctenidae display high specificity (oioxenous and stenoxenous), with sex-biased toward female bat hosts. Abundance correlates with host morphological characters including body mass and forearm length. sex ratios are mostly female-biased. Lyctocoridae exhibit sap-feeding with documented patterns.

Ecological Role

of vertebrates, particularly bats and birds. Potential : Cimicidae are known to vector . Plant-feeding members (Lyctocoridae) function as herbivores utilizing plant exudates. Predatory occur in some .

Human Relevance
