Zinaspa todara distorta de Nicéville, 1887 and Arhopala rama ramosa Evans, 1925 were recorded during the field survey from March 2016 to August 2016. A total of four individuals were recorded in the Adampur Forest and Satchari National Park of Sylhet Division in northeastern Bangladesh. These are the first records of these subspecies from Banglades...

Purple and Gold Flitter Zographetus satwa (De Nicéville, 1884), Family Hesperiidae, A New Record for Bangladesh

Our study focuses on the butterfly checklist of the Adampur forest beat, located in the Rajkandi Reserve Forest of Moulvibazar, Bangladesh. The study was conducted between December 2014 and January 2018 and aimed to document butterfly species in the area. A total of 266 butterfly species belong to 149 genera and 6 families (Papilionidae, Pieri...

Bangladesh is at the ecological transition between the Indo-Himalayan and Indo-Chinese subregions. The country also has one of the highest human population densities in the world and only 6% remaining natural habitat, putting much of its biodiversity at risk. With more than 1455 species worldwide, bats are an important, but threatened, component of...

Rhesus Macaques are widely distributed and ecologically diverse primate species that attract special focus from the research and conservation approaches. We studied population, activity budget, and societal perceptions of Rhesus Macaque at Old Dhaka City, Bangladesh from March 2015 to February 2016. Total count was used to determine the group size...

Understanding how niche differences evolve in ecologically similar species and how these differences are maintained is a fundamental question in ecology. We studied resource partitioning and niche overlap between the hoolock gibbon (Hoolock hoolock) and other frugivorous vertebrates from April 2016 to January 2018 in Satchari National Park, Sylhet,...

An understanding of the diet and the factors influencing food choice are important when considering conservation measures for primates. From April 2016 to March 2017, we studied the feeding behavior of the western hoolock gibbon (Hoolock hoolock) in response to seasonal variation of food in Satchari National Park (24°7'25.65"N, 91°27'5.43"E), Bangl...

We report the first confirmed record of the Himalayan Crestless Porcupine Hystrix brachyura (Linnaeus, 1758) in Sundarbans mangrove forest, Bangladesh. An individual was observed and photographed in May 2018. The finding ensures the occurrence of this porcupine in a new habitat and stretches this species’ geographic distribution.

An inventory of butterfly species in relation to food sources and climatic factors influencing their diversity and richness was studied from March 2015 to February 2017 in Satchari National Park. We recorded 195 butterfly species representing 125 genera under 21 subfamilies and 6 families. Nymphalidae was the more dominant family contributed 32.8%...

Satchari National Park, a crucial habitat for wildlife but its ongoing degradation impacts on ecology of primates. Capped langurs living in this park are facing challenges due to anthropogenic pressures. We studied group size, composition of capped langur based on line transect and direct count method, and conservation challenges using semi-structu...

During the study of butterflies of Bangladesh (Insecta: Lepidoptera) which carried out since June 2014 to March 2016, several expeditions were made by the authors in the different areas of Bangladesh and many butterfly species were collected and identified. Among them, five species namely, Zezius chrysomallus Hübner, 1823, Rapala tara de Niceville,...

Saccolaimus saccolaimus is an emballonurid bat and the only species from the genus Saccolaimus that occurs in South and Southeast Asia. It is medium-sized (FA 63.0–68.0 mm) and has a body covered with chocolate brown to black fur with whitish speckles on the dorsum (Nanayakkara et al., 2012). The muzzle of the bat is nearly hairless, ears are of mo...
