Food is plants including leaves, fruits and flowers. This species also feeds on insect larvae. The diet consists of 15-27% unripe fruit and 10-15% ripe fruit. They may eat fruits primarily to obtain seeds and prefer leaves which are rich in protein and low in fiber.

Different groups will feed on the same food source without significant aggression. Adult males do not disproportionately feed as often as other group members, females and juveniles.

They live in groups of about 7-20 individuals, including one or two adult males. Females usually have only one cub at a time and help each other raise the cubs. However, female langurs are also very aggressive towards female langurs from other groups.

Lutung budeng inhabits various types of forest including mangrove forest, coastal forest, freshwater swamp forest, lowland rain forest, tropical deciduous forest and mountain forest up to an elevation of 3500 meters. Also found in teak, rasamala, and acacia plantations.
