Acholla
Autumn Assassins
Acholla is a genus of assassin bugs (Reduviidae) in the tribe Harpactorini. Adults are most conspicuous in autumn, though they can be found from July onward in some regions. The genus contains three recognized species: A. multispinosa (widespread in eastern and central North America), A. ampliata (western North America), and A. tabida (California and Mexico). These predatory true bugs are primarily arboreal and associated with woodlands and orchards.
Acholla ampliata
Acholla ampliata is an arboreal assassin bug in the family Reduviidae, distributed across western North America from California to Colorado and south to Arizona, New Mexico, and Mexico. Adults are most active in autumn, though they can be found from July onward. The species is distinguished from similar assassin bugs by its relatively smooth body lacking prominent leg spines. It preys on caterpillars and other insects associated with trees, including pest species such as the Codling Moth.
Acholla multispinosa
Acholla multispinosa is a species of assassin bug in the family Reduviidae. It is the most widespread species in its genus, occurring across eastern North America from New England south through the Appalachians to Tennessee and North Carolina, and west through the Great Lakes region to Kansas, Nebraska, and southeast Iowa. Adults are most conspicuous in autumn, though they can be found beginning in July. The species is arboreal, primarily inhabiting woodlands and orchards.
Apiomerus
Bee Assassins, Bee Assassin Bugs
Apiomerus is a genus of brightly colored, conspicuous assassin bugs in the family Reduviidae, commonly known as bee assassins. The genus contains approximately 110 described species and represents the largest clade within the monophyletic tribe Apiomerini. Members are characterized by their use of plant resin as 'sticky traps' to capture prey, a trait unique among assassin bugs. Females possess specialized tibial combs for resin collection and application onto egg masses, providing maternal care. The genus exhibits significant sexual dimorphism and extreme diversity in genital morphology, hypothesized to result from sexual selection driving speciation.

The species belongs to the genus Apiomerus, whose members are frequently observed hunting on flowers where they ambush pollinators.
Apiomerus flaviventris
Yellow-bellied Bee Assassin, bee assassin bug
Apiomerus flaviventris is a predatory assassin bug in the family Reduviidae, commonly known as the yellow-bellied bee assassin. This species is notable for its specialized feeding habits targeting bees and its remarkable use of plant-derived chemical defenses.

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 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.

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.
Zelus janus
Two-faced Assassin
Zelus janus is a species of assassin bug in the genus Zelus, first described by Stål in 1862. Like other members of this genus, it possesses the characteristic 'sundew' predatory adaptation: specialized glands on the forelegs secrete a sticky substance that traps prey. The species name references the Roman two-faced god Janus, though the specific reason for this epithet is not documented in available sources. It is one of approximately 71 species in the genus Zelus, which is distributed primarily in the Americas.
Zelus longipes
milkweed assassin bug, sundew assassin bug
Zelus longipes is a medium-sized assassin bug (Reduviidae: Harpactorinae) distributed across the southern United States, Central America, and South America (excluding Chile). The species is notable for its bright red and black coloration and its unique prey-capture strategy using sticky secretions on the forelegs—an adaptation that inspired the common name "sundew assassin bug." It has been evaluated as a potential biocontrol agent for agricultural pests including fall armyworm (Spodoptera frugiperda), picture-winged flies (Ulidiidae), and Asian citrus psyllid (Diaphorina citri), though its generalist predatory habits and documented attacks on beneficial insects such as honey bees and parasitoid wasps complicate its practical application.

Zelus nugax
Zelus nugax is a species of assassin bug in the family Reduviidae, first described by Stål in 1862. As a member of the genus Zelus, it possesses the characteristic sticky forelegs used to capture prey, a trait that has earned these insects the common name 'sundew assassin bugs.' The species is distributed across the Americas, with records from the Caribbean, Middle America, North America, and South America. Like other Zelus species, it is a predatory insect that feeds on other small arthropods.
Zelus tetracanthus
four-spurred assassin bug, sundew assassin bug
Zelus tetracanthus, commonly known as the four-spurred assassin bug, is a predatory true bug in the family Reduviidae. Adults measure 10–16 mm in body length and are recognized by a distinctive row of four spurs across the thorax. The species employs a unique prey-capture strategy using sticky secretions from specialized leg glands rather than muscular grasping. Both adults and nymphs produce these adhesive substances to immobilize prey. The species has been evaluated as a potential biological control agent for saltcedar leaf beetles (Diorhabda spp.) in tamarisk management systems.
