In 140 hours of sampling, 3123 individuals, distributed in 169 species, were registered. Nymphalidae was the most sampled with approximately 53% of the recorded species. Nine species sampled were still no registered for the State. The Shannon-Wiener diversity index was higher in fragment of Villa Faguense, place less disturbed. The Simpson and Berger-Parker dominance indexes had been more representative in fragment of Schoenstatt Sanctuary, with higher number of abundant species. Among the species captured 126 (74,55%) are accidental, 25 (14,80%) are accessory and 18 (10,65%) are constant.
