The diversity of diurnal butterflies and their relationship with the guamo, Inga ornata, reproductive phenology in a forest shepherding agroecosystem in Quindio, Colombia was studied. Monthly samples of two transects of 50 x 2 m were carried out using entomological nets, traps baited with decomposed fruit and direct observations of l. ornate visiting butterflies were performed. The number of l. ornate flowers and fruits available in these transects was also counted monthly. A total of 142 butterfly species was recorded, 116 in pastures and 59 associated with I. ornata trees. A higer representation of the nectar feeding guild was found in the area of study. The richness, abundance and diversity of butterflies showed a tendency to increase during the months with higher availability of flowers and * Fr: 23-VII-2011.
