会飞的狐猴能够使用连接到四肢，身体和部分尾巴的皮肤薄膜（翼膜）滑行。马来狐猴（Galeopterus variegatus）是东南亚特有的狐猴。以前的信息，这一物种的饮食习惯一直是轶事，并对其饮食组成进行了研究很少。从兄弟种的信息，我们预测马来飞狐猴是食叶的。我们首先尝试了定量分析的饮食组成的马来飞狐猴连同食物供应在西爪哇，印度尼西亚，全年。马来亚飞狐猴的食物季节性变化：12月至7月的叶子主要与雨季（12月至6月）重叠，8月至11月的果实主要与旱季（7月至9月）重叠。当水果丰富时，粪便中水果的比例增加，而粪便中树叶的比例减少，或者飞狐猴将食物从树叶转移到水果。在此期间，树叶丰富，这并不能解释粪便的减少。这意味着飞狐猴在一年中的大部分时间里以树叶为食，但当树叶也很丰富时，它们会转向水果。飞行狐猴的饮食组成的突然变化是不同的同域食叶灵长类动物，爪哇lutung（Tracypithecus auratus），其中饮食组成表现出从树叶到水果的逐渐变化。这种种间差异可能是由身体大小和/或消化生理学的差异引起的。
Flying lemurs are able to glide using a thin membrane of skin (patagium) connected to their limbs, body, and part of tails. The Malayan flying lemur (Galeopterus variegatus) is endemic to Southeast Asia. Previous information on food habits of this species has been anecdotal, and few studies on their dietary composition have been conducted. From the information of sibling species, we predicted that the Malayan flying lemurs to be folivorous. We firstly tried a quantitative analysis of the dietary compositions of the Malayan flying lemurs together with food availability in West Java, Indonesia, throughout the year. The Malayan flying lemurs seasonally changed foods: leaves from December to July largely overlapping with the rainy season (October–June) and fruits from August to November largely overlapping with the dry season (July–September). When fruits were abundant, the proportions of fruits in the feces increased while proportions of leaves in the feces decreased, or the flying lemur shifted their foods from leaves to fruits. In this period, tree leaves were abundant, which did not explain the decrease in the feces. This implies that the flying lemurs fed on tree leaves in the majority of the year but they shifted to fruits when they were abundant though leaves were also abundant. The abrupt changes in the dietary composition of the flying lemurs were different from those of the sympatric folivorous primate, Javan lutung (Trachypithecus auratus), for which dietary composition showed a gradual change from leaves to fruits. Such inter-specific differences would be caused by differences in body sizes and/or digestive physiology.
