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.

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.

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.

Megalotomus 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.

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.
