| 研究區域描述 | Khangchendzonga Landscape, which encompasses the state of Sikkim and the districts of Darjeeling Himalaya (Darjeeling and Kalimpong) in the state of West Bengal (26.49 N to 28.12 N and 87.99 E to 88.79 E) is a part of the the Eastern-Himalayan region of the Himalaya biodiversity hotspot (Mittermeier et al., 2011). The region falls under the Warm pre-humid Agro-Ecological Zone (AEZ), and has been recognized as one of the agro-biodiversity hotspots of India. This AEZ is characterised by high precipitation (2,000 - 4,000 mm), lesser potential evapotranspiration (<1,000 mm) and longer growing seasons (>210 days). The elevation within the region varies from less than 50 meters in the foothills of Darjeeling to the towering height of 8,586 meters, represented by Mt. Khangchendzonga. |

取樣方法
Adult odonates were sampled using the transect count method. Permanent line transects of 200m length and 5m width were laid in different land use types.
| 研究範圍 | The sampling was conducted in the Khangchendzonga Landscape (Figure 1) , which encompasses the state of Sikkim and the districts of Darjeeling Himalaya (Darjeeling and Kalimpong) in the state of West Bengal (26.49 N to 28.12 N and 87.99 E to 88.79 E) The region is a part of the the Eastern-Himalayan region of the Himalaya biodiversity hotspot (Mittermeier et al., 2011). The region falls under the Warm pre-humid Agro-Ecological Zone (AEZ), and has been recognized as one of the agro-biodiversity hotspots of India.

| 品質控管 | The odonates which remained unidentified in the field were photographed and later identified with the help of official portal of odonates of India (Joshi et al., 2019) and available literatures (Fraser, 1933, 1934 & 1936; Subramanian, 2005; Subramanian and Babu, 2017). |
方法步驟描述:
- These transects were laid along artificial rivulets, water channels and paddy pools in the agricultural landscape. A slow and steady pace was maintained during the transect walk and all the individuals of odonates found within the 5m band on both sides of the transect were recorded along with identification details. Sampling was carried out between 09:00 and 14:00 hours during calm and sunny days because most odonates are active and the probability of encounter was high during this time.
