Sikkim marks 50 yrs of statehood with butterfly-watching race

"We started the 16-day Butterthon, the first-of-its-kind event specific to butterflies, on 1 May. This is not a test of speed but a leisurely race to spot the ecologically important butterflies across Sikkim," says Sonam Wangchuk Lepcha, the president of the Butterfly Society of Sikkim-TPCF.
