Aotus trivirgatus eat primarily fruits, insects, nectar and leaves. They will also complement their diet with lizards, frogs and eggs for protein. During times when food is scarce, they seek out mostly nectar, figs and insects. At this time of year they seem to have the advantage over similar sized diurnal species that were chased away from these food sources by larger diurnal monkey.
