As a part of the biodiversity impact assessment for the proposedSankosh hydroelectric power project, a survey was carried out along the SankoshRiver catchment to study the butterfly diversity. The aim of the study was to identifyspecies of conservation priority, their seasonality and to know the butterfly diversitypotential of the area. Surveys were carried out during five different seasons (winter,spring, pre-monsoon, monsoon, post-monsoon) lasting 18 days from January 2009to March 2010. Pollard walk method was used to assess the diversity on four-linetransects within 10–12 km radius of the proposed dam site. Two hundred and thirteenspecies, including 22 papilionids, were thus sampled. Eleven species amongst theseare listed in Schedules I and II of the Indian Wildlife (Protection) Act, 1972, of which10 taxa (Pareronia avatar avatar, Nacaduba pactolus continentalis, Porostas alutacoelestis, Elymnias vasudeva vasudeva, Mycalesis mestra retus, Melanitis ziteniuszitenius, Charaxes marmax, Athyma ranga ranga, Neptis manasa manasa and Neptissoma soma) are of conservation priority as they are ‘rare’ in occurrence across theirdistribution range in the region. The maximum number of species (128) were recordedduring the spring season (March) and lowest (66) during July (monsoon). The seasonalpattern of variation in diversity was very typical of the pattern found in other areas of thelower foothills and adjoining plains of the Himalaya. Relative abundances of butterfliesduring spring varied significantly (p
