Baksha & Choudhury species of buterfies in the country. (1983, 1985) reported 33 species comprising of 17 pierids The Kaptai Natonal Park (KNP) situated at Kaptai and 16 papilionids. Larsen (2004) annotated a checklist Upazila (sub-district) in Rangamat District falls between of 236 species. Ahmad et al. (2009) compiled 148 species the Karnaphuly River and Kaptai mountain ranges in Encyclopedia of Bangladesh. Chowdhury & Hossain (22.50N and 92.330E) (Figure 1). It is about 57km north (2013) documented a photographic feld guide with 225 of Chatogram (Chitagong) City and 12km south of species of buterfies from Bangladesh. IUCN Bangladesh Rangamat Town comprising an area of 54.64km² (2015) stated status of 305 species of buterfies. There is (5,464ha, 13,502acres). The park was previously known no other more comprehensive list of buterfies available as Sitapahar Reserve and was declared a natonal park in Bangladesh. Habib et al. (2016), however, recorded in 1999. It comprises two forest ranges: Kaptai and 146 species of buterfy from Kaptai Natonal Park (KNP) Karnaphuli. The KNP is sub-tropical mixed evergreen including Prosotas dubiosa. Hitherto, fve species under forest decked with hills, streams, valleys and plain lands. the genus Prosotas: bhutea, dubiosa, lutea, nora, and The area in the landscape context is very good, but pia have been previously recorded from Bangladesh disturbed by shifing cultvaton, secondary plantaton (Chowdhury & Hossain 2013; Larsen 2004). P. aluta is and human setlement. Nonetheless, the KNP is very reported from India, Myanmar, Malaysia, Philippine, rich in fora and fauna. The area is known as a buterfy Thailand, Indonesia, Singapore, Vietnam, China, Nepal, hotspot in Bangladesh (Habib et al. 2016). and Bhutan but not in Bangladesh untl this report (Evans The survey was conducted on buterfy diversity 1932; Cassidy 1990; Hirowatari 1992; Huang & Xue 2004; twice a month from January 2017 to December 2018.
