Some of our most beautiful winged creatures are moths, especially the giant silk moths such as the Atlas Moth and luna. The larger, more ornate species have inspired many an artist, and dazzled scores of people who stumbled into one in the wild. Biologically, moths rank high among our most important groups of organisms. Adult moths serve as food for many predators, perhaps most notably bats, and a number of birds. Moths also serve as a major food source for many species of spiders. Moth collections were carried out from evening onwards till morning on next day by using Light trap. The identification of moths was carried out in laboratory with help of identified specimens of museum and literature. The present study reveals that a total of 13 species have been identified. A maximum of 8 sightings of Black witch moth and 7 sightings of Virginian Tiger Moth was noted. The diversity index of the 55 individuals of moth species collected shows that species dominance of 0.09157 and 0.09025±0.1339. The present study has been carried out to elucidate a fauna which was previously unknown, and it is a small step towards a complete taxonomic understanding of moth species in the Cauvery basin region.
