Reduviidae
Assassin Bugs, Ambush Bugs, Kissing Bugs, Wheel Bugs, Thread-legged Bugs, Bee Assassins, Millipede Assassins, Masked Hunters
Reduviidae is a large cosmopolitan family of true bugs (Hemiptera: Heteroptera) comprising approximately 7,000 described species across more than 20 subfamilies. The family is predominantly terrestrial and predatory, with members employing diverse hunting strategies including ambush predation, active pursuit, and specialized prey capture using modified forelegs or sticky secretions. A notable exception is the subfamily Triatominae, whose members are hematophagous ectoparasites of vertebrates and vectors of Chagas disease. Most species possess a distinctive narrow neck, sturdy body, and curved proboscis that fits into a stridulatory groove on the prosternum, producing sound when rubbed against ridges. The family exhibits remarkable morphological diversity, with body sizes ranging from 12 to 36 mm and coloration spanning cryptic browns and blacks to aposematic reds, oranges, and metallic blues.
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.
Triatoma protracta
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.
