Bumdeling Wildlife Sanctuary is a great place for butterflies and the only place in Bhutan where Ludlow's Bhutan Glory(Bhutanitis ludlowi), the national buttefly, is found.

It flies mainly in the month of August. Ludlow's Bhutan Glory was rediscovered in 2009, 75 years after the only two known specimens were collected in the same area. Other prime butterfly watching locations include the forest and farm roads from the Old Dzong to Phodrung and Gangkhar and the main road to Trashi Yangtse between Kencholing and Buyang(Km 24-32), especially along the creeks.
