Grass seeds (8.33%) 3 (8.33)
and other invertebrates, living or dead, were collected. Some of them were
large and highly aggressive. Ants, especially Gnamptogenys, Odontomachus,
Pheidole, Azteca, and Camponotus, were an important part of this diet (Pie
2004; Pratt 1989). The same pattern was reported in a study by Giannotti and
Machado (1992). They recorded 20 types of food of animal origin (insects
and invertebrates) and several others of vegetal origin (like seeds, pulp, leaves,
