This work incorporates two methods that macroinvertebrate bio-monitoring and DNA barcoding, in an effort to gain a greater understanding of how traditional taxonomic approaches and DNA barcoding, helps in interpretation of water quality and phylogenetic lineage of insects. The present work is carried out to find the effect of the phenomenon in the Kurangani streams from August 2018 to January 2019. Shannon and Simpson index were highest in November 2018 and lowest in January 2019 and it shows climatic changes which have an impact on insect’s diversity. DNA barcoding of Stenopsyche kodaikanelensis which shows close relationship with Chimarra sp and the Indian species S.kodaikanelensis shows closer phylogeny with Chinese species S.brevata. By comparing the barcodes of Trichoptera and Lepidoptera in Kurangani falls, Anisocentropus sp (Trichoptera) is in closer lineage with Anthene lycaenina (Lepidoptera) and significantly tells that both arises from a common ancestor.
