Alydus
broad-headed bugs
Alydus is the type genus of broad-headed bugs (family Alydidae), comprising approximately 11 described species including two extinct species. Species occur across North America, Europe, and temperate Asia. Members of this genus are characterized by their broad, rounded heads and are frequently observed feeding on dung, carrion, and other extra-phytophagous materials alongside butterflies and other insects. Nymphs of at least one species exhibit ant mimicry and may develop in association with ant nests.
Alydus conspersus
broad-headed bug
Alydus conspersus is a species of broad-headed bug in the family Alydidae, first described by Montandon in 1893. It is one of three recognized subspecies within the species complex. The species is distributed across North America with documented records from Arizona, Colorado, Louisiana, Massachusetts, and Michigan. Like other members of the Alydidae, it is associated with feeding on seeds and has been observed utilizing extra-phytophagous food sources including animal dung.
Alydus scutellatus
Alydus scutellatus is a species of broad-headed bug in the family Alydidae, first described by Van Duzee in 1903. This small true bug belongs to a group commonly known for their seed-feeding habits, though members of the family have been documented engaging in extra-phytophagous feeding behaviors including carrion and dung consumption. The species has been recorded from western North American localities including British Columbia, Colorado, Montana, and New Mexico.
Cydamus borealis
Cydamus borealis is a species of broad-headed bug in the family Alydidae, described by Distant in 1881. It belongs to the subfamily Micrelytrinae and tribe Micrelytrini. The species has been recorded from Central America and North America, with specific distribution records from Guatemala and Texas.
Esperanza
Esperanza is a genus of broad-headed bugs in the family Alydidae, established by Barber in 1906. The genus contains at least one described species, E. texana. These true bugs belong to the infraorder Pentatomomorpha and are part of the subfamily Micrelytrinae within the tribe Micrelytrini. The genus is primarily known from Texas based on available distribution records.
Esperanza texana
Esperanza texana is a broad-headed bug and the sole described species in the genus Esperanza. It belongs to the family Alydidae, a group of true bugs characterized by their expanded, triangular heads. The species has been documented in Texas and surrounding regions, with confirmed host plant associations on Senna species (Leguminosae). Fifth-instar nymphs have been described morphologically, indicating nymphal development occurs directly on host plants.
Hyalymenus longispinus
broad-headed bug
Hyalymenus longispinus is a species of broad-headed bug in the family Alydidae, first described by Stål in 1870. It belongs to a family of true bugs characterized by broad, flattened heads. The species has been documented in the Caribbean region and Florida, with 268 observations recorded on iNaturalist. As a member of Alydidae, it is likely associated with leguminous plants, though specific ecological details for this species remain limited.
Hyalymenus subinermis
Hyalymenus subinermis is a broad-headed bug in the family Alydidae, described by Van Duzee in 1923. The species occurs in Central America and North America. As a member of the genus Hyalymenus, it belongs to a group of alydine bugs commonly associated with leguminous plants.
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.

quinquespinosus
Lupine Bug
Megalotomus quinquespinosus, commonly known as the lupine bug, is a broad-headed bug in the family Alydidae. It is found across North America. While many alydids are primarily plant-feeders, this species has been documented feeding on carrion and dung, including the remains of small mammals in predator scat. This behavior represents an unusual expansion of diet beyond typical seed-feeding habits seen in related species.
Neomegalotomus
Neomegalotomus is a genus of broad-headed bugs in the family Alydidae, established in 1998. The genus contains at least two described species: N. parvus and N. rufipes. Most biological knowledge derives from studies of N. parvus, a Neotropical pest of legume crops. The genus is characterized by broad head morphology typical of Alydidae and is associated with Fabaceae hosts.
Neomegalotomus rufipes
broad-headed bug
Neomegalotomus rufipes is a species of broad-headed bug in the family Alydidae. It was described by Westwood in 1842. The species occurs in the Caribbean region and parts of North America. Like other members of Alydidae, it possesses the characteristic broad, flattened head that gives the family its common name. Information on its biology and ecology remains limited.
Protenor australis
Protenor australis is a species of broad-headed bug in the family Alydidae, described by Hussey in 1925. The genus Protenor belongs to the subfamily Micrelytrinae, a group of true bugs characterized by their broad, flattened heads relative to body size. Distribution records indicate presence in Middle America and North America. The species remains poorly documented in published literature, with minimal observational data available.
Protenor belfragei
broad-headed bug
Protenor belfragei is a species of broad-headed bug in the family Alydidae, first described by Haglund in 1868. It is native to North America and has been documented in scattered locations across the eastern and central United States. As a member of the Alydidae family, it belongs to a group of true bugs commonly known as broad-headed bugs due to their widened head shape relative to other heteropterans.
Stachyocnemus
Stachyocnemus is a genus of broad-headed bugs in the family Alydidae, established by Stål in 1870. The genus contains a single described species, S. apicalis. Members of Alydidae are characterized by their broad, flattened heads and are commonly known as broad-headed bugs. The genus is part of the subfamily Alydinae within the superfamily Coreoidea.
Stenocoris tipuloides
neotropical rice bug
Stenocoris tipuloides, commonly known as the neotropical rice bug, is a broad-headed bug in the family Alydidae. The species occurs in the Americas, with records from South America, Florida, and Texas. It belongs to a genus of true bugs associated with rice and other graminaceous crops.
Tollius setosus
Tollius setosus is a species of broad-headed bug in the family Alydidae, first described by Van Duzee in 1906. It is one of the few recognized species in the genus Tollius, which belongs to the subfamily Alydinae. The species is known from western North America, with confirmed records from California. As a member of the Alydidae, it shares the family's characteristic broad, flattened head shape. Limited information is available regarding its biology and ecology.
