The Kameng Natural Heritage (KNH) in Arunachal Pradesh’s West Kameng district has recorded the seasonal arrival of the rice swift (Borbo cinnara), a skipper butterfly, as part of its ongoing butterfly monitoring programme.
According to KNH, the sighting is significant because Bomdila, located at an altitude of around 8,500 feet, presents challenging weather conditions for butterfly observation. Despite these difficulties, the discovery has generated excitement among butterfly enthusiasts and conservationists, who are hopeful of recording more species in the coming weeks.
The organisation noted that clear and sunny weather is essential for butterfly sightings, as butterflies are generally more active under such conditions. However, this season has witnessed fewer sunny days compared to the previous year, making monitoring efforts more challenging.
The rice swift belongs to the Hesperiidae family, commonly known as skipper butterflies. These butterflies are usually small to medium in size and are recognized by their rapid, darting flight patterns. Their wings often display shades of brown, orange, or yellow, although appearance varies among species.
KNH also reported sightings of the orange punch butterfly during the current season. However, the organisation observed a decline in the number of Ludlow’s Bhutan Glory (Bhutanitis ludlowi), a rare species belonging to the swallowtail family and closely associated with the eastern Himalayan region.
Expressing concern over threats to butterfly habitats, KNH urged residents to avoid introducing invasive alien plant species and instead plant more native flowering plants that can provide nectar for adult butterflies.
The organisation also cautioned that excessive use of pesticides and herbicides can severely affect butterflies and other pollinating insects. The removal of host plants, which are vital for butterfly breeding, can further threaten their survival.
Calling for collective conservation efforts, KNH appealed to residents to help protect Bomdila’s natural vegetation and habitats. It emphasised that preserving local ecosystems is essential for sustaining the rich diversity of Himalayan butterfly species found in the region.
