The mitered leaf-monkey is primarily a folivorous species, but will also consume fruits, flowers, and seeds. The leaves taken generally are immature ones that have a low level of lignins and tannins. This is a diurnal and an arboreal species. The mitered leaf-monkey has a unimale social system and a polygynous mating system. Females perform most of the grooming bouts in the group.
Males leave the natal group before adolescence.
The mitered leaf-monkey gives birth to a single offspring. Fleagle, J.G. 1978. Locomotion, Posture, and Habitat Use of Two Sympatric Leaf- monkys in West Malaysia. In Recent Advances in Primatology, vol. 1, Behaviour , eds.
