This
true lemur has not been studied intensively in the wild, but it is known to be fairly social. Group sizes vary from four to eleven individuals on average. Females are dominant as in most lemur species, and there are usually more males than females in each social group. The blue-eyed black lemur is thought to be
polygynous. Females give birth to one or two offspring in June or July, after a gestation of 120 to 129 days. The young are weaned after about 5–6 months, and reach maturity at about 2 years of age. It may live between 15 and 30 years in captivity, with little data recorded on their longevity in the wild. It demonstrates a
cathemeral activity pattern, being awake sporadically throughout the day. The occasional nighttime activities are thought to be based on the intensity of the moonlight. Little is known of its vocalizations, but it has been observed making a variety of grunts, chirps, barks and clicks. The males are known to make a sharp 'scree' when distressed. The blue-eyed black lemur has also been observed to be a highly aggressive species. There is frequent infighting between troop members, especially during the breeding and birthing seasons. In captivity it has been observed committing infanticide against other species of lemurs, a behavior that is usually uncommon, especially in captivity.
Diet Fruit, pollen, and nectar make up the bulk of this lemur's diet. During the dry season when food is scarce it may eat leaves, seeds and berries and rarely insects. It may also raid farmlands and eat some of the crops, which may lead to it being shot by farmers. The blue-eyed black lemur helps propagate many rain forest plants. Since it digests the flesh but not the seeds of the fruits it eats, it spreads the seeds of more than 50 different plant species (deposited in a fresh pile of fertilizer), and some plants may have evolved specifically to be dispersed by this lemur. The blue-eyed black lemur also pollinates many plants while it eats nectar and pollen from the plants' flowers. == Habitat ==
