[en] Mittermeier’s sportive lemur (Lepilemur mittermeieri) is an endangered primate endemic to the Ampasindava peninsula, in north-west Madagascar. Lepilemur are known to be folivores with a low metabolic rate, but no specific investigation of the diet of Mittermeier’s sportive lemur has been reported. In 2015 and 2016, we conducted a field study of the species in two areas of the Ampasindava peninsula, involving direct observation of individuals equipped with radio-collars. We verified that Mittermeier’s sportive lemur is a solitary forager. We identified a total of 77 tree species consumed and a large variation in the spectrum of species used within the two studied sites. Most of the plant material consumed was made of leaves, with few fruits.
