Located in the northeastern corner of New Territories, Luk Keng is the largest freshwater marsh in Hong Kong. Backed by slopes that descend from Pat Sin Leng, Luk Keng provides diverse wetland habitats, including marshes, streams, reedbeds, fishponds and pools for dragonflies to fly over and perch in. It is one of a few sites in Hong Kong at which a very high diversity of dragonflies has been recorded.

The site is zoned as Conservation Area on the relevant Outline Zoning Plan.

The surveys focused on adults and were carried out on sunny/fine and windless days between 09:00 and 15:00. Walking transect count method along a standard route was adopted. All the dragonflies observed along the transect were identified visually, with the aid of a pair of close-focusing binoculars, to species level following Wilson et al. (2004).
