The Scarlet Dwarf is the smallest dragonfly in the world, measuring only two centimetres in length. You can find the bright red dragonfly in Luk Keng, the northeastern corner of the New Territories.

The Scarlet Dwarf usually lives in weedy margins of ponds and swampy wetland areas, and the wetland in Luk Keng is a dragonflies' wonderland in summer.

The wetland features wet paddy fields and a large bed of lush green mangroves.

It is also the home for our feathered friends �V egrets. Several hundred herons and egrets live in the wetland. The most commonly seen are the snow white great egrets and the slightly smaller little egret.

If you have binoculars handy, zoom in for a close-up of the night heron. This species is distinguished by its blue-black upperparts and light grey body.

Overhead, a Chinese pond heron flutters up in the sky. Its glittering white wings strike an attractive contrast with its brown-back plumage.

No binoculars? Don't worry. You can always catch a good view of egrets from a nearby sidewalk.

When enjoying your wetland tour, do not disturb any wildlife and observe quietly. Do not step on the mangroves as this might damage them.
