The present study characterized the macrobenthic entomofauna of the Sardinas river and the La Delicia stream. Their environmental quality water was determined by applying the BMWP/Col (Biological Monitoring Working Party for Colombia) index in two sampling points, distributed in the Sardinas river and La Delicia stream, during the months of May and June 2017. For its collection, a Surber net was used. In the laboratory, they were classified and identified in class, order and family levels. The specimens were analyzed by calculating the richness (S), abundance (N) and relative abundance (%). A total of 90 individuals belonging to 16 morphospecies were collected. The Hemiptera order with the Veliidae family was the most abundant, encompassing most of the organisms collected 33.33%. The less represented group was the order Diptera with the family Tipulidae with 1.52% of the individuals collected. The water quality was Moderate for the river Sardinas (BMWP/Col 59) and Good for the La Delicia stream (BMWP/Col 75). The present study characterized the community of macroinvertebrates in the study area and the ecological quality of the studied bodies of water.
