The objective of this work was to analyze the composition of the Noctuidae communities at Reserva Biológica de Ibirapuitã (Alegrete) and at Parque Estadual do Turvo (Derrubadas), Parque Estadual de Rondinha (Sarandi) and Parque Estadual do Espigão Alto (Barracão). Ten light traps were used to collect the insects from November/2000 to February/2001, sampling one night per area. The lepidopterous were identified at family and subfamily levels and, when it was possible, at genera and species levels. A total of 6,374 noctuids belonging to 249 taxa, distributed in 17 subfamilies were collected. The large number of species observed in all areas emphasize the importance of Conservation State Unity for the biodiversity maintenance.
