Habitat
This species inhabits dry deciduous forests and spiny bush in northwestern Madagascar. It prefers areas with dense undergrowth and trees for shelter, typically at elevations below 500 meters. They are found in regions with seasonal rainfall, avoiding more humid rainforests.
Diet
MacArthur's mouse lemur primarily eats insects like beetles and moths, as well as fruits and nectar from flowers. They forage nocturnally, using their agile movements to catch prey or lick sap from trees. Feeding occurs mainly in the trees, helping them avoid ground predators.
Behavior
These lemurs are solitary and nocturnal, spending their nights foraging and their days sleeping in tree hollows or leaf nests. They exhibit territorial behavior, marking areas with scent glands, and communicate through vocalizations and scent marking. Males may travel farther than females during mating seasons, but they generally avoid social interactions.
Conservation Status
MacArthur's mouse lemur is classified as Endangered by the IUCN due to habitat loss from deforestation and agriculture. Population trends are declining, with major threats including fragmentation of forests and potential impacts from climate change.
