Abstract: Butterflies are valued components of grassland ecosystems both for their aesthetic nature and they provide as pollinators of the ecosystem services. Loss and fragmentation of native habitats, along with other disturbances associated with intensive agriculture can have dramatic effects on butterfly communities. The close link between butterflies and their natural environment make them good candidates for use as ecological indicators. Hence an attempt has been made to study the diversity and pollination tendencies of butterflies between organic crop fields and pesticide sprayed crop fields. The research was set out to establish whether organic and conventional farming systems support different levels of pest and non-pest butterflies. In the present study maximum insect abundance and total number of individuals were recorded in organic fields. The study also proved that organic farming practices can help in the population build-up of natural enemies and pollinators. However there was remarkable difference in Shannon index and Simpson index of diversity between organic and chemical fields. Phytophagous insect populations were very low in number in organic farms. Hence organic farming practices may encourage natural enemies’ diversity and may not be favourable for pests.
