As the days shorten animals store fat, metabolism, temperature and sexual activity decrease, and animals became more tolerant, nesting in large groups. The pattern was reversed when day length started to increase, leading to the beginning of sexual activity. Male testes increased in size and female estrus commenced. 1-3 infants are produced in a litter. Locomotion Locomotion is quadrupedal.
Animals range through all heights in the forest.
M. rufus will attempt and even consume large insects. They will watch, but rarely attempt to capture solitary flying insects, but appear attracted to flowering trees both for the nectar and for the pollinating insects. Based on fecal data it is likely that M. rufus occasionally forage for ground-living insects. It is likely that fruit is the primary food source, rather than insects as small body size would predict. These two species are both nocturnal small-bodied Cheirogaleidae , both with high fruit, insect diets, both competing for Bakerella spp .
