In the present study analysed the distribution of macro invertebrates communities and they are useful as ‎bioindicators by assessing the water quality parameters in freshwater stream of kurangani in Theni district. A total number of 1234 ‎aquatic insects belonging to 15 genera and 17 families from 10 orders were collected from August 2017 to March ‎‎2018. Three different sites were selected for the insect collection among three sites, site one and site two were less ‎polluted. The physico- chemical water quality parameters were analysed the results falls within the acceptable ‎range. The diversity indices like Margalef indices, Shannon and Simpson were found to be a maximum significant ‎compare to other indices‎‎‎‎‎.
