A survey was conducted from June 2016 to July 2017 in three locations within GFMU: Jamdo, Chimithanka, and Jedekha. A total of 90 species belonging to 52 genera and five families of butterflies were recorded. Nymphalidae was dominant with 38 species, followed by Lycaenidae with 19, Pieridae with 15, Papilionidae with 11, and Hesperiidae with seven species. Diversity of butterfly species was highest in farmland associated with pockets of forest cover in the lower valley, and a decreasing trend was observed towards higher elevations. The maximum species richness (83 species) was recorded from Chimithanka between 2500m & 2900m, where agriculture is associated with patches of forest, streams, forest edges, and open scrub land. Butterfly diversity was lowest at Jedekha above 2,900m (37 species), an area dominated by mixed conifer forest wi...

We conducted a retrospective study to evaluate the snakebite epidemiology in Sarpang District located in the subtropical zone of southern Bhutan. In this study, 78 snakebite cases treated in Gelephu Referral Hospital over a period of three years from 2013 to 2015 were evaluated based on the statistical record maintained by the medical administration. Twenty-eight (35.89%) cases developed signs and symptoms of envenomation and the remaining 50 (64.01%) were found to be cases of non-venomous bites. Forty-four males and 34 females were found to be affected by snakebites within the period. While snakebites were observed in all age groups, the large majority (n=51, 65.38%) were in adults aged between 21 and 50 years. Most of the venomous bites (68%) occurred during the monsoon season, particularly between May and ...
