The occurrence of various kinds of flora and fauna in a region reflects its biological diversity. India is gifted with rich moth fauna, about 4438 moths recorded by Cotes, E.C. and Swinhoe, C. (1887-89) in catalogue of moths of India & 5277 moths recorded by Hampson G.F. (1892-96) in Fauna of British India. Moths are known to be one of the most appropriate taxonomic groups for environmental evaluation and have great economic importance. The study attempted to identify macro moth species diversity of family Noctuidae in Chamba district. A total 144 specimens were collected from various localities.
