Cimex
bed bugs, bedbugs
Cimex is a genus of obligate hematophagous insects in the family Cimicidae, commonly known as bed bugs. The genus includes species specialized on different hosts, with C. lectularius (common bed bug) feeding primarily on humans and C. hemipterus (tropical bed bug) occurring in warmer regions. Other species such as C. pipistrelli, C. pilosellus, and C. adjunctus specialize on bats. Bed bugs are wingless, nocturnal parasites that have undergone global resurgence since the late 1990s, likely due to insecticide resistance, changes in pest control practices, and increased international travel.
Cimex lectularius
common bed bug, bed bug
Cimex lectularius is a hematophagous ectoparasite in the family Cimicidae, primarily associated with human dwellings. The species has undergone a global resurgence since the late 1990s following decades of suppression by DDT and other insecticides. Populations show documented resistance to multiple insecticide classes including pyrethroids and pyrroles. The species comprises at least two host-associated lineages: one feeding on humans and another on bats.
Cimexopsis nyctalis
Chimney Swift Bug
Cimexopsis nyctalis is a species of bed bug in the family Cimicidae, commonly known as the Chimney Swift Bug. It is an ectoparasite specifically associated with the Chimney Swift (Chaetura pelagica), a North American bird species. The insect has been documented from nest material and roosting sites of its host. Its narrow host specificity and obligate parasitic lifestyle distinguish it from the more generalist bed bugs that feed on humans.
Hesperocimex
Hesperocimex is a genus of bed bugs (family Cimicidae) containing at least two described species: H. coloradensis and H. sonorensis. Members of this genus are ectoparasites of birds, specifically associated with nest-dwelling species. H. sonorensis has been documented parasitizing purple martins, woodpeckers, swallows, and Ferruginous Pygmy-Owls.
Hesperocimex coloradensis
Colorado Bed Bug
Hesperocimex coloradensis, commonly known as the Colorado bed bug, is a species of bed bug in the family Cimicidae. It was described by List in 1925. The species occurs in Central America and North America, though detailed biological information remains limited.
Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

vicarius
American swallow bug, cliff swallow bug, swallow nest bug
Oeciacus vicarius is a blood-feeding cimicid bug specialized as an ectoparasite of colonially nesting American cliff swallows (Petrochelidon pyrrhonota). It is widely distributed across North America, where it inhabits swallow nests in natural and anthropogenic structures. The species is a known vector of Buggy Creek Virus (Alphavirus, Togaviridae). Though it will bite humans when encountered, it does not establish persistent infestations in human dwellings.
Ornithocoris pallidus
Ornithocoris pallidus is a species of bed bug in the family Cimicidae, first described by Usinger in 1959. It belongs to the subfamily Haematosiphoninae, which comprises cimicids associated with birds and bats. The genus Ornithocoris is distinguished from other cimicid genera by its association with avian hosts. The species epithet 'pallidus' refers to its pale coloration. Distribution records indicate presence in North America and South America, though specific details regarding its biology and ecology remain poorly documented in the available literature.
