This research aimed to identify the trophic groups supplied from the families of aquatic insects found in 12 dairy farms classified according to their vegetation cover, obligatorily in the hydrographic watershed of Arroio da Seca, Taquari-Antas portion. Sampling was carried out from February to November 2019, along the banks of streams of each property. A total of 2,741 belonging to aquatic insects were collected and identified, belonging to 8 orders and 38 families. There was no significant difference between the richness and abundance of the proportional trophic groups of aquatic insects between the collection points, however, in the composition of families there was no difference. The study reveals that the environmental conditions of farms, in relation to vegetation cover in their Permanent Preservation Areas, have an influence on determining the structure and composition of the aquatic entomofauna community.
