Deltochilum is a genus of true dung beetles in the family Scarabaeidae native to the Americas. There are more than 100 described species in Deltochilum. [2] [1] [3] [4] [5] Unusually for a dung beetle, a few species in the genus, including D: valgum , are predators that kill and feed on millipedes. [6]
Dung beetles are beetles that feed on feces. Some species of dung beetles can bury dung 250 times their own mass in one night.
Phanaeus vindex, the rainbow scarab, is a North American species of true dung beetle in the family Scarabaeidae. It is found in eastern and central United States and in adjacent far northern Mexico. It is the most widespread species of Phanaeus in the United States and it has a wide habitat tolerance. It may hybridize with the generally less common P. difformis.
The scarab beetle subfamily Scarabaeinae consists of species collectively called true dung beetles. Most of the beetles of this subfamily feed exclusively on dung. However, some may feed on decomposing matter including carrion, decaying fruits and fungi. Dung beetles can be placed into three structural guilds based on their method of dung processing namely rollers (telecoprids), dwellers (endocoprids) and tunnelers (paracoprids). Dung removal and burial by dung beetles result in ecological benefits such as soil aeration and fertilization; improved nutrient cycling and uptake by plants, increase in Pasture quality, biological control of pest flies and intestinal parasites and secondary seed dispersal. Well-known members include the genera Scarabaeus and Sisyphus, and Phanaeus vindex.
Deltochilum valgum is a nocturnal, Neotropical species of dung beetle in the family Scarabaeidae, which has evolved a predatory lifestyle. While most other members of the true dung beetle subfamily feed on faeces or decomposing matter, D. valgum is highly specialised for eating millipedes; such a transition from scavenger to carnivore is rare. Whether this is novel adaption in this species or an ancestral adaption in the genus is unclear; at least two other species, Deltochilum kolbei and D. viridescens, which are not particularly closely related to D. valgum, also kill and feed on millipedes.
Onthophagus is a genus of dung beetles in the Onthophagini tribe of the wider scarab beetle family, Scarabaeidae. It is the most species-rich and widespread genus in the subfamily Scarabaeinae, with a global distribution.
Sceliages, Westwood,, is a sub-genus of the Scarabaeus dung beetles, and are obligate predators of spirostreptid, spirobolid and julid millipedes, having renounced the coprophagy for which they were named. The genus is near-endemic to Southern Africa, Sceliages augias exceptionally ranging as far north as the Democratic Republic of Congo.
Oxyomus sylvestris is a species of aphodiine dung beetle in the family Scarabaeidae. It occurs in Europe, the Near East, and North Africa. It is saprophagous rather than a "true" dung beetle.
Phanaeus adonis is a species of true dung beetle in the family Scarabaeidae, found primarily in north-central Mexico, but also ranging into Cameron County in far southern Texas, United States.
