Analysis of the stomach contents of 28 armadillos, collected during a 14-month period at Pipinas, Argentina, showed that about 63.6% of the weight of prey items was comprised of animal remains, 18% was plant material, and the remaining 18.4% was undetermined organic remains. Insects were the most frequent diet item, followed by plant material, amphibians, reptiles, and lastly birds and mammals in similar proportion. During autumn, plant material was the most abundant item, followed by vertebrates and invertebrates. During winter invertebrates prevailed, followed by a lower percentage of vertebrates and scarce plant remains. Invertebrates were also predominant during spring, whereas plant material and vertebrates comprised very low percentages.
