Correspondence: Md Kawsar Khan Lecturer Department of Biochemistry and Molecular Biology, Shahjalal University of Science and Technology, Sylhet, Sylhet-3114, Bangladesh Three new records of butterfly from university of Chittagong and Shahjalal University of science and technology in Bangladesh Md Kawsar Khan Abstract Butterflies are considered one of the most studied orders of class Insecta. However, the butterfly fauna of Bangladesh are not well documented. The current research was carried out from March 2014 to July 2014 with an aim to document new species to contribute and update the butterfly checklist of Bangladesh. From the butterfly survey in different regions of Bangladesh, three new butterflies were recorded as distribution. Arhopala agaba agaba Hewitson, 1862 (Purple-Glazed Oakblue) and Deudorix epijarbas amatius Fruhstorfer, 1912 (Cornelian) were documented from University of Chittagong (CU) campus whereas Delias acalis Godart, 1819 (Red Breasted Jezebel) was recorded from Shahjalal University of Science and Technology (SUST) campus.

Introduction Bangladesh (20°34″ N to 26° 38″ N and 88° 1' E to 92° 41") is a land of 147,570 square kilometers, a country of Southeast Asia surrounded by the Indian states West Bengal, Meghalaya, Assam, Mizoram and Tripura [1] . The eastern region of the country is bordered by Myanmar and the Bay of Bengal determines the southern territory of the country. The geographic location of the country engenders climatic variation. These enormous climatic variation and diverge floral and faunal communities have created an apposite milieu for butterfly (Lepidoptera). Butterflies are important element of ecosystem mainly because of their pollination activities [2] . Moreover, they are considered as good ecological indicators because of their sensitivity towards the environmental and climatic changes [3] . Hence, it is indispensable to know the exact number of butterflies, their diversity and distribution throughout the country to monitor ecological status. However, in Bangladesh, the butterfly fauna are not well documented compared to the other fauna like birds and mammals [4] . The most distinguished studies have been carried out by Larsen T.B, (2004). According to Larsen only 311 butterfly species have been recorded from Bangladesh [5] . Neogi AK et al. added 5 more new species to the checklist which take the total number of butterflies to 316 [6] . Nevertheless, this is not the comprehensive documentation of the butterflies of Bangladesh. Considering the floral diversity and habitat variation it is predicted that 500-550 butterfly species should be present in Bangladesh [5] . The current research was carried out with the aim to document the diversity and distribution of butterfly as well as to record new species in Bangladesh. 2. Methods and Materials 2.1 Study area University of Chittagong (CU) campus (22°46′94.40′′ N and 91°79′02.54′′ E) (Fig 1 A) is located southeast region of Bangladesh spread over 1754 acre. The area had mixed vegetation comprising ornamental, fruit plants, shrubs and grasslands. The major floral species of the area include Artocarpus heterophyllus, Tectona grandis, Swietenia macrophylla, Terminalia arjuna, Shorea robusta, Polianthes tuberosa, Lantana camara, Hibiscus rosa sinensis, Bougainvillea glabra etc. Shahjalal University of Science and Technology (SUST) campus (24°55′09.06′′ N and 91°49′54.24′′ E) (Fig 1 B) is situated northeast region of Bangladesh. The campus is spread
