Social Behavior
A fat-tailed dwarf lemur shares a nest tube with another nocturnal prosimian. Click image for larger version.
Dwarf lemurs forage in solitude at night. During the day they congregate, in packs of up to five to a tree hole, while they sleep. The composition of these sleeping groups changes seasonally, and often animals do choose to sleep alone.
Sleeping sites generally consist of hollow trees, whose cavities have been cushioned with leaves. Otherwise, they are spherical nests made of dead leaves concealed in heavy undergrowth.
During the mating season, mouse lemur males sleep with females more often than during other times of the year. For the rest of the year females sleep with their dependent offspring in groups of up to 15.
Females generally occupy "home ranges" in central areas of a group's range, while a single male may overlap his home range with those of several females. Female prosimians, in general, are considered dominant to males, but this may not be universal.
