The present study was conducted at Gangajalghati, a village near the forest of Bankura district from West Bengal that has a tropical wet and dry climate where moth diversity has not been explored before. The village was surveyed between January 2016 and December 2018. The present study has recorded a total of 1,328 individual moths belonging to 13 families, 31 subfamilies, 80 genera, and 90 species. Three species—Condylorrhiza diniasalis (Walker, 1859), Argyrocosma inductaria (Guenée, 1858), and Oraesia emarginata (Fabricius, 1794)—are reported for the first time from West Bengal and Eublemma roseonivea (Walker, 1863) shows its westernmost distribution in West Bengal, India. It was earlier reported from India (Assam), China, Taiwan, the Philippines, Malaya, and Borneo.
