Trox
hide beetles
Trox is a genus of hide beetles in the family Trogidae, subfamily Troginae. The genus currently contains approximately 70 species divided among three subgenera: Trox (Trox), Trox (Niditrox), and Trox (Granulitrox). These beetles are specialized scavengers that colonize animal remains in advanced stages of decomposition, feeding on dried skin, hair, feathers, and connective tissue. They are among the last insects to visit carcasses, appearing after most other carrion fauna have departed. The genus has undergone significant taxonomic revision, with former subgenera Phoberus and Glyptotrox elevated to full genera and numerous species synonymized.
Trox capillaris

Trox capillaris is a species of hide beetle in the family Trogidae, first described by Thomas Say in 1824. As a member of this family, it is associated with the late stages of vertebrate decomposition, feeding on dried skin, hair, feathers, and connective tissue. The species occurs in the Nearctic region, primarily in the central and eastern United States and southern Canada.
Trox fascifer
hide beetle
Trox fascifer is a species of hide beetle in the family Trogidae, found in western North America including California and British Columbia. As a member of this family, it is associated with decomposing animal remains, particularly dried skin, hair, feathers, and other keratinous materials. The species was described by LeConte in 1854.
Trox floridanus
hide beetle
Trox floridanus is a species of hide beetle in the family Trogidae, first described from Florida in 1957. As a member of this family, it is associated with decomposing animal remains in advanced stages of decay, feeding on dried skin, hair, feathers, and connective tissue. The species is documented from the Nearctic region, specifically Florida, USA. Hide beetles in this genus are cryptic insects that typically become coated in debris and exhibit thanatosis (death-feigning) when disturbed.
Trox foveicollis
hide beetle
Trox foveicollis is a species of hide beetle in the family Trogidae, currently classified under the genus Glyptotrox. The species is known from the central and eastern United States and adjacent Canada. Like other hide beetles, it is associated with decomposing animal remains in advanced stages of decay.
Trox frontera
Trox frontera is a hide beetle in the family Trogidae, first described by Vaurie in 1955. It is currently treated as a synonym of Glyptotrox frontera. Members of this genus are cryptic beetles that specialize in consuming dried animal remains, including skin, hair, feathers, and connective tissue. They are among the final colonizers of carcasses, arriving after most other insects have departed.
Trox gemmulatus

Trox gemmulatus is a hide beetle in the family Trogidae, native to arid and semi-arid regions of western North America. These beetles specialize in consuming desiccated animal remains, including dried skin, fur, feathers, and connective tissue. Adults are typically 8–11 mm in length and are known for their rough, debris-caked appearance and thanatosis behavior—feigning death when disturbed. The species is most active during spring and is frequently associated with the final stages of vertebrate decomposition.

Like other trogids, it belongs to a group of beetles specialized in consuming dried animal remains. The species has been recorded from Kansas and Nebraska in the central United States.
Trox robinsoni
Trox robinsoni is a hide beetle in the family Trogidae, described by Vaurie in 1955. Members of this genus are specialized decomposers that colonize carcasses in advanced stages of decay, feeding on dried skin, hair, feathers, and other keratinous materials when little else remains. The species occurs in the north-central United States and central Canada.

Trox scaber is a small hide beetle in the family Trogidae, measuring 5–8 mm. It has a nearly cosmopolitan distribution and is strongly associated with bird nests, where both adults and larvae develop. The species feeds on dried animal remains including skin, feathers, fur, and small dry carcasses. It is characterized by rough, sculptured elytra and pronotum with distinctive bristly scales, and exhibits a remarkable death-feigning behavior when disturbed.
Trox spinulosus
Hide beetle
Trox spinulosus is a hide beetle in the family Trogidae, a group of scarab beetles that specialize in consuming dried animal remains. The species was described by Robinson in 1940 and is currently treated as a synonym of Glyptotrox spinulosus in some taxonomic databases. Like other trogids, it is associated with the final stages of carcass decomposition, feeding on desiccated skin, hair, feathers, and connective tissue. These beetles are cryptic in appearance and behavior, often caked in debris and feigning death when disturbed.
Trox tuberculatus
hide beetle
Trox tuberculatus is a hide beetle in the family Trogidae, a group of scarabaeoid beetles specialized in feeding on dried animal remains. The species occurs in the Nearctic region, with records from multiple U.S. states. Like other Trogidae, it is associated with the late stages of carcass decomposition, consuming dried skin, hair, feathers, and connective tissue. The beetle exhibits characteristic defensive behaviors including thanatosis (death-feigning) and debris-covering that render it cryptic and difficult to detect.
