The weasel sportive lemur (Lepilemur mustelinus), also known as the greater sportive lemur, weasel lemur, or greater weasel lemur, is a species of lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. Described by Isidore Geoffroy Saint-Hilaire in 1851, it is the type species of genus Lepilemur. It is threatened by habitat loss, climate change and hunting.
Phylogenetic studies show that the weasel sportive lemur diverged from its closest relatives, the Betsileo sportive lemur (L. betsileo) and James' sportive lemur (L. jamesi), approximately 1.18 million years ago. These three species are further nested within a clade containing all the Lepilemur species that inhabit Madagascar's eastern rainforests, with the exception of the small-toothed sportive lemur (L. microdon).
The weasel sportive lemur has long, dense fur that is chestnut-brown on the back, often displaying a dark midline stripe. The face is gray or brown, with the cheeks, throat and abdomen slightly lighter. The tail darkens towards the tip. There have also been reports of bright orange morphs in otherwise normally colored populations. It is a... Wikipedia →

Possible
About 20% of wildlife watchers report a Weasel Sportive Lemur sighting in Mantadia National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 12 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February and November
In those months about 40% of wildlife watchers report a Weasel Sportive Lemur in Mantadia National Park on a given day, against under 5% in January, March–April and October, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Weasel Sportive Lemur sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Mantadia National Park, in our data
Mantadia National Park is the only park on Wallace's Line with enough records to rate Weasel Sportive Lemur sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Primates
The closest relatives of the Weasel Sportive Lemur that you can see in Mantadia National Park (order Primates) are Indri (about 90%), Diademed Sifaka (about 80%) and Common Brown Lemur (about 80%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Weasel Sportive Lemur is recorded against all the mammals logged in Mantadia National Park (14 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
