Onthophagus hecate blatchleyi
Scooped Scarab
Onthophagus hecate blatchleyi is a small dung beetle subspecies in the family Scarabaeidae, recognized as a regional variant of the Scooped Scarab. Males possess a distinctive broad, forked horn projecting from the thorax, which they use in combat for mating rights. The species has been documented visiting both dung and carrion, including bird carcasses and cattle feces. Research indicates populations are vulnerable to certain livestock parasiticides, particularly those with persistent residues in dung.
Oscarinus matiganae
A dung beetle species in the family Scarabaeidae, described by Paulsen in 2006. It belongs to the genus Oscarinus, which comprises beetles associated with vertebrate dung. The species has been recorded from Nebraska and Texas in the United States.
Oscarinus rusicola
Oscarinus rusicola is a dung beetle species in the family Scarabaeidae, found across much of Canada and the northern and eastern United States. It is primarily associated with cattle dung, where it buries feces into soil. This activity reduces methane emissions, recycles nutrients, and suppresses pest fly populations. The species is sensitive to cattle parasiticides that persist in dung.
Oscarinus stuessyi
Oscarinus stuessyi is a dung beetle species in the family Scarabaeidae, described by Gordon and Skelley in 2007. It belongs to the subfamily Aphodiinae, which includes many species associated with dung decomposition. The species occurs in the south-central United States. Like other members of its genus, it likely contributes to nutrient cycling in pasture ecosystems.
