Earlier studies on Hanuman langurs (Presbytis entellus) around Jodhpur found them entirely vegetarian (Mohnot, 1974;Winkler, 1988). However, recent observations in the open scrub forests of Jodhpur reveal that scale insects may constitute a regular part of their diet and that insectivory is particularly prevalent in the monsoon months July – September. The insect eating in this habitat seems to support the “Energy/nutrient maximization” hypothesis ofHamilton andBusse (1978).
