Nepal Butterfly Spotting: Best Sites and Seasons
Nepal records over 650 butterfly species, from swallowtails in Chitwan's sal forest to Himalayan apollos above the treeline. Here are the best places and months to find them.
Overview
Nepal's butterfly diversity rivals much larger countries. The Terai's tropical forests produce the greatest species count, while mid-hill sites like Phulchoki and Shivapuri near Kathmandu are accessible year-round. High-altitude species including Himalayan apollo and alpine argus are found on open slopes above 3,500m in summer.
Chitwan National Park and its buffer zone produce outstanding butterfly lists. The forest edges near Sauraha record common birdwing (Nepal's largest butterfly), multiple species of jezebel and yeoman, and the spectacular Kaiser-i-Hind swallowtail. The best months are March through May and again October–November, avoiding the wet monsoon when flying conditions are poor.
Phulchoki hill (2,760m) south of Kathmandu is Nepal's most-studied butterfly site. The forest road winding to the summit records over 300 species on good days in April and May. No special permits are needed for Phulchoki.
Bardiya's jungle edges and the Narayani riverbank in Chitwan host mud-puddling aggregations — dozens of swallowtails and pierids gathering on damp sand to absorb minerals — a spectacular and photogenic sight on calm mornings.
