, and Omorgus
as a subgenus of Trox
; classification here follows(1)
; now the two are treated in different subfamilies(2)
~40 spp. in our area(1)(3)
, ~300 spp. in 4 genera worldwide(4)
4-19 mm (NA spp.)(5)
, some Australian spp. up to 31 mm(5)
Roughly sculptured, often covered with a crust of soil(6)
Trox - 3-12mm, rounded scutellum [left]
Omorgus - 9-20mm, hastate scutellum [right]

on carrion at late stages of decomposition, on owl pellets, in bird & mammal nests, on carnivore scat containing hair/bones; more common in drier regions(9)
Year round, at least in the South
skin, bone, hair, feathers; Trogidae are among the last scavengers to visit dry animal remains(9)
