Here, there is the data regarding the abundance of fruit-feeding butterflies sampled in Catimbau National Park, Pernambuco state, northeastern Brazil. OF1 to OF9 correspond to the nine study plots of old-growth forest. Taxon Old-growth forests.Sampling of fruit-feeding butterflies was carried out monthly from May 2018 to April 2019. Each plot had one sampling unit composed of five portable bait traps, totaling 45 traps across our study landscape. The traps were arranged a distance of at least 30 m from each other and suspended at a height of between 1 and 1.5 m above the ground. The traps remained open during seven consecutive days per month and were checked every 48 hours, when baits were replaced. The number of trap-days was considered the sampling effort, i.e., the total number of traps used in the field (45 traps) multiplied by the number of days sampling lasted (84 days), which result in 3,780 trap-days.
