Its temperature is Selection of study sites very high in summer and low in winter which varies from The present study was conducted at three different 2.8 degrees in winter to 52 degrees in summer. Rainfall study sites (Site 1, 2 and 3) with three different habitat defines the climate of the district. South-west monsoon types located in the Baghmundi block of Purulia District is the principal source of rainfall in the district. Average (22.600–23.500N & 85.750–86.650E), West Bengal, India annual rainfall varies between 1,100mm and 1,500mm (Fig. 1). Name, geographic location, altitude, habitat (Das 2016). The relative humidity is high in the monsoon and vegetation types of the three study sites are season, being 75% to 85%, but in summer it comes presented in Table 1. The selection of study sites were down to 25% to 35%. Due to undulated topography, made based on the range of habitat types and ease of nearly 50% of the rainfall flows away as runoff.

Data collection Image 1. Study site S1, Baghmundi Village and adjoining area The butterflies were observed and recorded directly in the field. A combination of direct search technique (Sutherland 1996) and opportunistic sighting methods © Supriya Samanta were applied for the present study which were conducted for two consecutive years (January 2014 to December 2015) to record butterfly diversity and abundance. Observations were made at a frequency of twice a month for each study area (a total of 48 samples from each study site) involving different habitat types. Observations were made between 08.30hr and 15.30hr during periods of good weather (no heavy rain or strong winds). This timing was found ideal based on preliminary observations done during different times of the day in the study sites. Butterflies were photographed using digital cameras (Nikon D5200 and Canon Power shot SX500IS) and identified using Image 2. Study site S2, Turga Dam area suitable keys (Evans 1932; Wynter-Blyth 1957; Haribal 1992; Kunte 2000; Kehimkar 2008). In critical conditions when identification was not possible by the naked eye © Supriya Samanta or could not be photographed, as in the case of cryptic butterflies, they were captured by hand net following Tiple (2012), identified and released in the same habitat from where they were captured with least disturbance.
