The butterflies at Natura Park in Veracruz, Mexico, were studied during their annual peak in abundance. Butterflies were collected from 21 March through 21 June during spring 2014, for a total of 14 days of collection which were equivalent to 126 hours of fieldwork. Recorded were 775 specimens of 120 species in 81 genera, 15 subfamilies, and five families (573 specimens of 68 species of Nymphalidae, 135/25 of Pieridae, 31/11 of Lycaenidae, 27/nine of Papilionidae, and nine/seven of Riodinidae). The species richness indicated that March was the month with the largest number of species (71), with Nymphalidae the dominant family. In a curve of accumulation of species, the asymptote did not become stable, while Chao 2 estimated the presence of 173 species versus the 120 found, indicating an absence of 50 species still to be reported. Results of the study were compared with the fauna at Xalapa, Veracruz. It was observed that 64 species were exclusive to Natura Park and 56 species were found at both study areas. The Jaccard Index showed 70% similarity in species between both study areas. The species Danaus plexippus plexippus L. and Eumaeus childrenae (G. Gray) seem to be threatened.
