Coprophanaeus lancifer is a copro-necrophagous beetle endemic to the Amazon region. Although beetles belonging to the subfamily Scarabaeinae primarily feed on dung, some have a greater diet plasticity that includes carrion, fungi, rotten fruits and invertebrates. The diet of the scavenger beetle C. lancifer mainly consists of vertebrate carcasses, although it is also attracted to mammal faeces. Here, we describe the first record of this species feeding on fruits of the genus Nectandra.
