''Deltochilum valgum'' is a nocturnal species of dung beetle in the family Scarabaeidae, which has evolved a predatory lifestyle. While most other members of its family feed on faeces, ''D. valgum'' is highly specialised for eating millipedes; such a transition from scavenger to carnivore is rare. ''D. valgum'' prefers live millipedes to dead ones, and seems to take no other food. It tends to kill millipedes much larger than itself, at long. The beetle itself is about long. In a typical attack, the beetle grasps the millipede's body with its mid and elongated, curved hind legs and then bites into the coiling prey at a joint between body segments. Sometimes this results in the prey being decapitated. The beetle then drags the victim to feed on it. ''D. valgum'' is widely distributed in Central American rainforests. Two subspecies are recognised: ''D. v. acropyge'' Bates, 1887 and ''D. v. longiceps'' Paulian, 1938.〔(【引用サイトリンク】title=''Deltochilum valgum'' Burmeister 1873 )〕 ==References==
