Like most ‘true lemurs’ (Eulemur species), the red-fronted lemur is cathemeral (2) (8). This species eats mostly fruits, but has also been known to feed on leaves, bark, insects and other invertebrates (2) (7). In some areas, it may be an important seed disperser (2) (7). Predators of the red-fronted lemur are likely to include the fossa (Cryptoprocta ferox) and large raptors (2).
The red-fronted lemur is arboreal and travels primarily in the upper canopy (9), typically moving through the trees on all fours (2) (8). It is a social species, living in groups of 4 to 18 individuals (1) (7) which include several adults of both sexes (5).
Red-fronted lemurs can have large home ranges of over 100 hectares (1) (9), and use a range of calls to stay in touch while on the move (2) (7).
Reproduction in the red-fronted lemur is highly seasonal, with mating occurring in May and June and a single infant being born between September and October (1) (2) (7), after a gestation period of about 120 days (2) (7). The young red-fronted lemur is initially carried on the female’s belly, but after the first month or so is able to start moving about and is transferred to the female’s back (2). The young of this species are usually weaned by about January (1).
Although female red-fronted lemurs generally stay with their family group, or are sometimes forcibly evicted from large groups, males disperse from the group on reaching sexual maturity (4) (5). The red-fronted lemur usually reaches sexual maturity at two to three years old (2) (7) and may potentially live for up to 25 years in the wild (7).
