The order Lepdioptera is one of the largest insect order known for pest species among moths and bioindicators among butterflies. The latter also form a major portion of Wildlide (Protection Act, 1972) especially among the insects. The remarkable diversity of Lepidoptera has been compiled by Nieukerken et al. 2011, Heppner, 2014 worldwide but our knowledge of Indian diversity of order Lepidoptera is very poor. The present paper is an attempt to review the diversity and distribution of Lepidoptera in India.
