Abstract/ Executive Summary:

The lowland Sino-Himalayan butterflies are well represented here and much of the tropical fauna of Hong Kong and Guandong, southern China, and northern Indochina are also present in this area. Butterfly research on this kind of tropical area is still in the ongoing process in Bangladesh. Lawachara National Park (LNP) originally supported an indigenous vegetation cover of mixed tropical evergreen type1 . Butterfly fauna of LNP are considerably well documented than other forests in Bangladesh. From previous studies, total 160 numbers of species of butterflies had been recorded from LNP. We made several expeditions to LNP and recorded six species (two species of Hesperiidae, three species of Lycaenidae, and one species of Papilionidae family) new to Bangladesh, which are briefly described in the current article. The Present survey was conducted in the North-east region of Bangladesh on Lepidoptera from 2013 to till now at Lawachara National Park, Moulvibazar and added six butterfly species new to Bangladesh as extension of their distribution.

Keywords: Records of Butterflies, Lawachara National Park, Bangladesh

Location: Moulvibazar, Bangladesh

Start Date: 22-03-2014

End Date:

Program Area: Pest Management

Commodity: Butterfly

Objectives:

This six new record denotes previous sampling gaps in the area and suggest further study to compile a complete checklist to take conservation initiatives.

Methodology:

Burara oedipodea belesis (Mabile, 1876; Branded Orange Awlet) was sighted in the coordinate of 24°20'11.83"N, 91°48'58.48"E; from Moulvibazar (LNP) on 22 March 2014 at 6.00 am (GMT: +06.00). The butterfly was taking liquids by rubbing proboscis on wet surfaces. Its flight was fast just above the ground and sat on a wet facial tissue again and again. The knowledge of host plants is still unknown, but the specimen was seen nearby Chlorophora excelsa. Larsen (2004) predicted Burara oedipodea belesis (Mabile, 1876) should be in Bangladesh. This species had reported from India, Nepal, Bhutan, Myanmar, Sri Lanka. Sighted individual was a male. Male has a compact, large, black and prominent circular brand from the base under the cell towards the middle of upper forewing. The two prominent black spots present on basal area of both under fore and hind wing. Underside of fore and hind wings with was a combination of orange and red color. Some bluish color in discal area with whitish shadow on vein 1 to 8 in basal to sub-marginal area. Edge of apex and costal area are brownish orange color. Tornal area of hind wing underside is suffused with orange color. Upper forewing of Burara oedipodea belesis has ochreous red costal brand which extends across cell base. Tagiades menaka menaka (Moore, 1865; Spotted Snow Flat) was photographed during perching on bird dropping in a sandy trail 24°20'40.45"N, 91°48'35.67"E; under poor sunlight from Moulvibazar (LNP) on 06 March, 2015 at 10.53 am (GMT: +06.00). This species was reported from some part of India (Himalayan foothills from Jammu & Kashmir to Arunachal Pradesh) and Nepal. Wingspan same like as Tagiades litigiosa. Upper forewing has semitransparent white spots with dark brown color. Outer two-thirds of upper hindwing has dark color move over rest of the middle parts are white color. This species is closely resembles the Tagiades litigiosa, excepting additional dark spots on the white area on upper hindwing. Under hindwing white except for brown costa and apical area. Suasa lisides lisides (Hewitson, 1863; Red Imperial) was photographed in the coordinate of 24°20'27.52"N, 91°48'7.51"E; from Moulvibazar (LNP) on 22 March 2014 at 10.12 am (GMT: +06.00). Larsen (2004) mentioned Suasa lisides in the appendix 01 ‘species recorded from ‘sylhet’ (‘silhet’) or cachar, but not included in the checklist and a few species recorded in error from Bangladesh’ and this record disprove Larsen’s the prediction7 . Flight of Suasa lisides lisides was moderately slow like as Hypolycaena othona othona. This rare species have been recorded from India (Assam-Arunachal Pradesh, Northeast), Myanmar and China. Tail present at the end of hindwing, broad reddish brown band from under fore wing leading edge to mid- area, continuing as line, margin broadly reddish brown. White under hindwing has two dark spots near leading edge.
