The present investigation was carried out to study butterfly diversity in some selected sacredgroves located in Alapad village, Thrissur district in Kerala for the period October 2020 to June 2021. In Kerala among Hindus, it was a common practice to assign a part of their land near the Tharavadu or house as the abode of goddess Durga or Serpent God Naga or Shasta and the place is called Kavu or Sarpakavu. Sacred Grove represents the major effort to recognize and conserve biodiversity (ethnic diversity) traditionally. Results showed that 40 species of butterflies representing 5 major families were recorded. Nymphalidae family showed the maximum no. of species (16species) followed by Papilionidae family (9species), Lycaenidae family (6species), Hesperiidae family (5species) and Pieridae family (4species). In conclusion, sacred groves help in the protection of many rare, threatened, and endemic species of plants and animals found in an area. This study area was rich in host plants and nectar plants. The study areas were rich in species diversity. A total of 40 species of butterflies (5 families) were recorded, among which majority was from Nymphalidae family. Out of these 40 species 22 species were commonly found throughout the period of observation in study area, 18 species were found occasionally. 7 species are protected under various schedules of the Indian Wildlife (Protection) Act, 1972.
