The black lemur occurs in moist forests in the Sambirano region of Madagascar and on nearby islands.

[9] Other foods eaten include flowers, leaves, fungi, some invertebrates and, especially during the dry season, nectar.

[5] The black lemur lives in groups of 2 to 15 members, including approximately equal numbers of males and females.

[10] Ranges overlap considerably, and population density can reach 200 individuals per square kilometer.

Once this is achieved the black lemur will rub the millipede around its body to get the toxins on its fur.

It is believed that they do this to help repel insects with the millipedes poison, though the toxins also appear to have pleasurable psychoactive effects on the lemurs.

[8] After a gestation of about 125 days, a single infant is usually born between late August and early October.
