A study about the species of Piperaceae that are consumed by a colony of Carollia perspicillata (Linnaeus, 1758) in Parque Municipal Arthur Thomas (82,72 ha) was carried out. Five available species of Piperaceae were found in the park: Piper aduncum Linnaeus, Piper amalago (Jacq.) Yuncker, Piper crassinervium H.B.K., Piper gaudichaudianum Kunth and Piper sp. C. perspicillata fed on all of these species. During the spring, the most abundant item was P. amalago, but the consumption of P. aduncum was the highest. At the beginning of the summer, P. crassinervium was the most abundant and most consumed item. At the end of the summer and during the fall, P. gaudichaudianum was the most abundant and consumed item, even in May, when P. amalago was the most abundant item. During the winter, the most highly available items were P. aduncum, Piper sp. and P. amalago, and the ones that were consumed the most were Piper sp., P. gaudichaudianum and P. aduncum. The results have shown that the preferences of C. perspicillata in the park are related to the greater abundance or the higher energetic value of the available Piperaceae. The greater search for the most energetic and least abundant species, which happened in the spring and winter, is related to the energy gain, that is, the species searches for food that will provide a greater quantity of energy per unit of consumption; and the greater search for the most abundant item, which occurred in the summer and fall, is related to saving the energy used in the search for food.
