Deltochilum valgum

Species of beetle

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.
