The macro- invertebrate fauna of river have a large biological significance and these organisms may be used to find out the water quality of streams. This study was carried out to know the benthic macro-invertebrates composition and to know its relationship with physical and chemical of water in the Jutial Nala. Benthic animals and water samples were collected from four different sites by D-frame net and samples were preserved by using alcohol. Most of the macro invertebrates collected were recognized to the species level. During the sampling a total of 1614 individuals were collected. From these individuals 1050 (65.06%) were found in station third, 273(17.91%) in station fourth, 179 (11.09%) in station 1 and 110 (6.82%) in second station. Jutial nullah was dominated by Diptera (68.65%) followed by Anopla (12.89%), Ehemeroptera (10.10%), Plecoptera (5.14%), Tricoptera (2.17%), Oligochaeta (0.86%, Coleoptera (0.12%), and Arachnida (0.06%) respectively. It was observed that the water of this water are slightly alkaline (pH=7.5), non-turbid (6.19NTU), and non-saline in nature (EC=161.25µS/cm) while the mean temperature of water was 14ºC.
