Abstract/ Executive Summary:

A butterfly species, Sinthusa nasaka Horsfield, 1829 (Narrow Spark) is recorded for the first time from the Rampahar (22 0 29'50.95'' N & 92 0 11'09.44''E) of Kaptai National Park under Rangamati District in Bangladesh. Three individuals of Sinthusa nasaka were recorded in the butterfly species diversity survey during December 2014 to June 2015 in this Park. Supplementary data on morphology, habitat ecology and geographical range of this species are given.

Objectives:

This paper presents the new record of Sinthusa nasaka from the Rampahar (22 0 29'50.95'' N & 92 0 11'09.44''E) of Kaptai National Park, Rangamati District of Bangladesh.

Methodology:

Study area: Kaptai National Park (22 0 30.08´ N latitude and 92 0 16.02´ E longitude) located in the Kaptai sub-district under Rangamati district on the south-eastern part of Bangladesh. It has an area of 5464.8 hectares and is 1600 ft. high from sea level. It is one of the major butterfly habitats in this country and almost all butterfly families available in Bangladesh are seen in this park and the total number of butterfly species exceeds 200 in the forest areas, although the actual count of species is still incomplete. These forests and plantations areas maintain a considerable number of trees, vines, climbers, hedges, shrubs, brushes and grasses. The rich plant diversity of this park provides many suitable niche areas for butterflies 3. Method A study was carried out in the Kaptai National Park during December 2014 to June 2015 to survey the diversity of butterflies. During this survey period S. nasaka were observed with naked eyes and photographed with a Canon EOS 1100D DSLR and 55-250mm Canon lens. A single specimen was caught with insect net for identification and measurement. After taking the measurements, the specimen was released immediately without harm. This specimen was not collected for preservation in the laboratory due to lack of permission from the Bangladesh Forest Department. The place, activities, resting tree, time and GPS coordination were noted instantly. Identifications were confirmed with the help of literatures by Evans (1932),

Achievement/Findings:

Kaptai National Park currently is under great threat of human settlement extension, over use of forest products through the reduction of trees for fuel and furniture, extension of cultivation land and burning of under growth of forest floor. The existence of the adult S. nasaka indicates that this forest has a good habitat of host plant for this butterfly species and proper conservation tools are recommended for saving this butterfly habitat.
