The species was found on bat guano in Bracken Cave, Comal County and in Ney Cave, Medina County. The beetles were collected during late summer (Kohls and Jellison 1948).  Omorgus suberosusis one of the most abundant, widespread generalist members of the family, occurring throughout most of the Western Hemisphere ( Vaurie 1955; Harpootlian 2001; Ratcliffe and Paulsen 2008). These are considered accidental collections.    Trox aequalisSay.Reeves et al.(2000)reported  T. aequalisliving in bat guano in  Georgia:Walker Co.: Fricks Cave.  Trox aequalisis a widespread species occurring in the central and eastern US. It is frequently found in various bird and mammal nests ( Vaurie 1955; Ratcliffe and Paulsen 2008). The association with nests of various facultatively cavernicolous animals could lead to additional cave collections. Because the species has only been reported once from caves, we consider it an accidental collection.     Trox laticollisLeConte.Peck and Christiansen (1990)gave a single record of  T. laticollisfrom a cave in Iowa.  Trox laticollisis a widespread eastern USspecies that is rarely collected. Most biological data indicates they prefer fox dens ( Vaurie 1955; Ratcliffe and Paulsen 2008). This apparent association with fox dens could lead to additional cave collections. Because the species has only been reported once from caves, we consider it an accidental collection.     Trox scaber(L.). Gardner (1986)reported a specimen from  Missouri:Miller Co.: Buzzards Perch Cave. “This adult specimen was collected from beneath excrement in a turkey vulture nest.”  Trox scaberis widespread in the northern half of the USand southern Canada, where it is infrequently collected. It is most often found in nests of various animals as well as old animal carcasses ( Vaurie 1955; Ratcliffe and Paulsen 2008). The association with nests of various animals could lead to additional cave collections. Because the species has only been reported once from caves, we consider it an accidental collection.  “  Troxsp.” Crawford and Veni (1981) report finding one dead specimen buried in guano in Sorcerer’ s Cave, Terrell County, Texas. Withouta study of their specimen to complete the identification, no additional comments can be made.
