The predation of army ants (Eciton rapax) was recorded during an observational study of the feeding behavior of a group of titi monkeys (Plecturocebus toppini) in an urban fragment of forest in Acre, Brazil. During one observed event, the group's adult female used its tail to retrieve ants, a type of behavior not observed previously in this genus. All incidents of on-forest floor foraging occurred during the dry season, when fruit was least abundant in the forest, while on other occasions, the ants were captured from tree branches and leaves. The observation of predation and ground-level foraging recorded in this study reinforce the adaptive capacity of P. toppini for survival in fragmented forests, and this was also the first record of the predation of army ants by this titi species.
在对巴西阿克里一片城市森林片段中一群伶猴（Plecturocebus toppini）取食行为的观察研究期间，记录了军蚁（Eciton rapax）的捕食情况。在一次观察到的事件中，该群体的成年雌性用尾巴去抓蚂蚁，这种行为在此属中此前未曾观察到。所有在森林地面觅食的事件都发生在旱季，此时森林中的果实最为稀少，而在其他时候，蚂蚁是从树枝和树叶上捕获的。本研究中记录的捕食和地面觅食观察结果强化了伶猴在碎片化森林中生存的适应能力，这也是该伶猴物种捕食军蚁的首次记录。
