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.

Stictocephala stimulea
Stictocephala stimulea is a treehopper species in the family Membracidae, first described by Van Duzee in 1914. Treehoppers in this genus are characterized by their enlarged, often ornate pronotum that extends over the body like a helmet or thorn. The specific epithet 'stimulea' suggests possible resemblance to or association with stinging organisms, though this refers to appearance rather than actual sting. Like other membracids, this species likely feeds on plant phloem sap using piercing-sucking mouthparts.

Triatoma indictiva
kissing bug
Triatoma indictiva is a blood-sucking assassin bug in the subfamily Triatominae, commonly known as a "kissing bug." It is a documented vector of Trypanosoma cruzi, the protozoan parasite that causes Chagas disease. The species occurs in Mexico and the southern United States, particularly Arizona and Texas. Adults measure 20–30 mm in length and are characterized by a pear-shaped body, black coloration with red lateral markings, and a tapered proboscis. Like other triatomines, it is primarily associated with vertebrate hosts in natural and peridomestic habitats.

Triatoma lecticularia
kissing bug
Triatoma lecticularia is a kissing bug in the subfamily Triatominae, a group of blood-feeding assassin bugs. It is a known vector of Trypanosoma cruzi, the parasite that causes Chagas disease. The species has been documented in North America and Mexico, with records extending to northwestern Mexico where it has been introduced. Like other triatomines, it is an obligate hematophagous insect requiring blood meals for development and reproduction. It has been found in dog kennels in Texas, where it poses transmission risks to canines.

Triatoma neotomae
kissing bug, woodrat bug
Triatoma neotomae is a species of kissing bug (subfamily Triatominae) in the assassin bug family Reduviidae. It is the smallest Triatoma species in the United States, found in south Texas and associated with woodrat (Neotoma) nests. Like other triatomines, it is a blood-feeding insect and a potential vector of Trypanosoma cruzi, the parasite that causes Chagas disease.

western bloodsucking conenose
Triatoma protracta is a blood-feeding assassin bug in the subfamily Triatominae, commonly known as the western bloodsucking conenose. Native to western North America, it serves as a vector of Trypanosoma cruzi, the protozoan causing Chagas disease, though its vector efficiency is considered secondary to some congeners due to its relatively long development time and defecation behavior. The species is primarily associated with woodrat (Neotoma) nests and occasionally invades human dwellings, where it may bite and cause allergic reactions. Laboratory studies indicate egg-to-adult development averages 6.7 months with 72.5% egg eclosion rates.

Triatoma recurva
kissing bug, blood-sucking conenose
Triatoma recurva is a kissing bug (Triatominae) native to Mexico and the southwestern United States. It is a blood-feeding assassin bug that serves as a vector for Trypanosoma cruzi, the parasite causing Chagas disease. The species has been documented from its natural host, the ringtail (Bassariscus astutus), and is found in domestic and peri-domestic environments. Laboratory studies indicate slower development and higher feeding requirements compared to related species, with egg-to-adult development exceeding 8.5 months.

Triatoma rubida
kissing bug, Arizona kissing bug
Triatoma rubida is a hematophagous assassin bug and important potential vector of Chagas disease in the southwestern United States and northern Mexico. Laboratory studies demonstrate it has the shortest egg-to-adult development time (~4 months) among comparable species, with high survival rates and rapid defecation behavior that enhances vector competence. In southern Arizona, the species is primarily associated with white-throated woodrat (Neotoma albigula) nests, with dispersal flights occurring from late May through mid-July when adults may be attracted to artificial lights and invade human dwellings. Females consistently defecate while feeding (93%), unlike males and immature stages, increasing transmission risk. The species shows 41.5-66% prevalence of Trypanosoma cruzi infection in some populations and has been documented feeding on humans.

Triatoma sanguisuga
Eastern Bloodsucking Conenose, Mexican Bed Bug, Kissing Bug
Triatoma sanguisuga is a blood-feeding assassin bug in the subfamily Triatominae, commonly known as the eastern bloodsucking conenose or kissing bug. It is the most widespread triatomine species in the United States and serves as a vector for Trypanosoma cruzi, the parasite that causes Chagas disease. Unlike highly efficient South American vectors such as Triatoma infestans, T. sanguisuga typically defecates after feeding rather than during, reducing but not eliminating transmission risk to humans. The species has been implicated in documented autochthonous human Chagas disease cases in the United States.
