I investigated the feeding ecology of l'Hoest's monkeys (Cercopithecus lhoesti) and blue monkeys (Cercopithecus mitis) in the Kalinzu Forest, Uganda. Although forest guenons are generally thought to be frugivores or folivores, these two guenons spent a large proportion of their time feeding on invertebrates. The l'Hoest's monkey and the blue monkey spent as much as 66 and 50% of their time on insectivory, respectively. These proportions of time spent on invertebrate feeding are higher than those reported elsewhere for forest guenons. L'Hoest's monkeys mainly utilized the area near the ground for invertebrate feeding, while blue monkeys utilized the area around 20 m above the ground. It seemed that guenons have an ability to change their diet according to the environment.
我对乌干达卡林祖森林中的洛氏猴（Cercopithecus lhoesti）和蓝猴（Cercopithecus mitis）的觅食生态进行了研究。尽管一般认为森林中的长尾猴是食果动物或食叶动物，但这两种长尾猴花费大量时间捕食无脊椎动物。洛氏猴和蓝猴分别将多达66%和50%的时间用于食虫。这些用于捕食无脊椎动物的时间比例高于其他地方报道的森林长尾猴的比例。洛氏猴主要利用地面附近区域捕食无脊椎动物，而蓝猴则利用离地面约20米的区域。似乎长尾猴有根据环境改变其饮食的能力。
