An attempt was made to survey for lepidopteran faunal diversity of Kolli hills, Namakkal District, Tamil Nadu from January to December, 2015. During the study period 1,077 lepidopterans were recorded by using various methods like aerial netting, light trap and host rearing. Out of which, the study area registered with 251 butterflies, 39 skippers and 787 moths. They were identified up to subfamily level with the help of standard taxonomic keys.

Among them, Noctuoidea was found to be dominant with 338 individuals followed by Papilionoidea (251). The superfamily, Papilionoidea recorded with four families viz., Papilionidae, Pieridae, Lycaenidae and Nymphalidae while the superfamily Hesperioidea found with only one family Hesperiidae. Among them, Nymphalidae was predominant with 83 numbers followed by Pieridae recorded 62 numbers.
