Pale-spotted Emperor (Anax guttatus): Pale-spotted Emperor is a large-sized dragonfly with strongly built body. Taking photo of Pale-spotted Emperor is not easy as it has rapid and direct flight, and only stops occasionally for rest. During summer, visitors can see Pale-spotted Emperor in Wetland Park patrolling above freshwater bodies.

Lesser Emperor (Anax parthenope julius): Lesser Emperor and Pale-spotted Emperor (Anax guttatus) are very similar. Both of them are robust-built dragonflies and swift flyers occurring in freshwater areas. However, Lesser Emperor is smaller in size and the upper part of its frons are multi-coloured.

Common Flangetail (Ictinogomphus pertinax): Common Flangetail is a common dragonfly in Wetland Park during summer. It is a large robust species easily seen on top of emergent plants or hovering along pond edges. The most distinctive character of Common Flangetail is the leaf-like projection near the end of its abdomen.

Blue Dasher (Brachydiplax chalybea flavovittata): Blue Dasher is an attractive dragonfly with blue, yellow and black coloured body and a pair of green eyes. It occurs in weedy areas around ponds and marshes, and sometimes in coastal areas.

Asian Amberwing (Brachythemis contaminata): Asian Amberwing usually occurs in ponds, streams and reed marshes, and even in slightly murky water. It can be distinguished from other yellow dragonfly species by its smaller size and orange wings.

Pied Percher (Neurothemis tullia tullia): Pied Percher is a small-sized dragonfly. Although it is widespread in Hong Kong, it often hides among aquatic plants like reeds, making it difficult to spot without careful observation. Wings of males are mainly black and white, and those of females are black, white and pale brown in colour.

Green Skimmer (Orthetrum sabina sabina): Green Skimmer is featured with its uniquely shaped abdomen and distinctive yellowish green and black stripes on thorax. Green Skimmer is so aggressive that it usually preys on other dragonflies and damselflies. On warm days, it often perches on rocks and emergent plants along the Stream Walk in Wetland Park.

Crimson Darter (Crocothemis servilia servilia): Males of Crimson Darter are red in colour, while females are basically yellow-coloured. Both the males and females have a black stripe along the dorsum of the abdomen. On sunny days in spring and summer, visitors can see groups of Crimson Darters gliding along the Stream Walk and the Succession Walk in Wetland Park.

Wandering Glider (Pantala flavescens): Wandering Glider is a common dragonfly in Wetland Park. Its supreme flying skill has earned it the name 'glider'. It is commonly seen in large groups during summer, especially before rain. Even in winter, it is occasionally found in sheltered areas.

Pied Skimmer (Pseudothemis zonata): Pied Skimmer is a black medium-sized dragonfly commonly found in reed marshes during summer. Part of its abdomen is white in males but yellowish white in females. Their abdomens seem to be taped with white or creamy white ribbons.

Variegated Flutterer (Rhyothemis variegata arria): Variegated Flutterer is a distinctive dragonfly in Hong Kong. Its forewings and hindwings have a distinct pattern of black and yellow and it flies like a butterfly. Variegated Flutterers can be found gliding in a large group near the end of summer.

Crimson Dropwing (Trithemis aurora): Compare to other libelluids, Crimson Dropwing is a relatively small species. However, the brightly coloured scarlet red body is still an impressive characteristic which catches the sights of visitors easily. During hot sunny days, males usually raised its abdomen towards the sun, thus reduce heat intake.

Orange-tailed Sprite (Ceriagrion auranticum ryukyuanum): Orange-tailed Sprite is a large damselfly with strongly built body, and preys on smaller damselflies. This robust species has a long flight period from spring to early winter. With distinctive olive green thorax and orange red abdomen, Orange-tailed Sprite can be spotted easily even when it hides among aquatic plants.

Common Bluetail (Ischnura senegalensis): Common Bluetail is one of the few damselflies that can tolerate fairly brackish water. In fact, Common Bluetail is common in streams and ponds. It has green thorax and the eighth and ninth segments of its abdomen are in blue and in black respectively. It usually hides among plants near water.

Four-spot Midget (Mortonagrion hirosei): Four-spot Midget was once listed as an endangered species by the International Union for Conservation of Nature and Nature Resources (IUCN). It is a rare species in Hong Kong but can be found in Wetland Park. It is a tiny damselfly occurring in brackish water, with two pairs of characteristic apple green spots on the dorsum of the thorax.

Blue Sprite (Pseudagrion microcephalum): Blue Sprite is not widespread in Hong Kong but fairly common in Wetland Park. Thoraxes of the males are greenish-blue in colour with black stripes. It can be found around aquatic plants in streams and water ponds, and is commonly seen along the Stream Walk in Wetland Park during summer.

Wandering Midget (Agriocnemis pygmaea): Wandering Midget is one of the smallest dragonfly species in the world. It often hides among aquatic plants in streams and ponds. Wandering Midget is commonly seen along the Stream Walk and at the Life Zone in Wetland Park in spring and summer.

Orange-tailed Midget (Agriocnemis femina oryzae): Orange-tailed Midget is a very common and widespread damselfly in Hong Kong. However despite on its tiny size, it could be overlooked easily. Usually Orange-tailed Midget can be found in ponds and marshes, since March every year. Be aware of its appearance as it has different forms. The female can be present in red colour while older male can be covered with pale bluish-white over its thorax.

Eastern Lilysquatter (Cercion melanotum): Eastern Liliysquatter looks very similar to Blue Sprite (Pseudagrion microcephalum). The main difference lies on the segment 2 of their abdomen. Eastern Lilysquatter has predominantly black segment 2 while Blue sprite’s segment 2 is only partially black in colour. Both of them have similar preferences in their habitat: lowland streams. Eastern Lilysquatter can be found in Wetland Park occasionally.

Scarlet Basker (Urothemis signata signata): The Scarlet Basker looks similar to the male Crimson Darter and male Crimson Dropwing, all of which are red in colour. Unlike the brilliant red Crimson Darter and scarlet red Crimson Dropwing, Scarlet Basket is actually dark red in colour. Meanwhile, the female Scarlet Basker is generally yellow in colour. They can be seen on conspicuous branches on warm days.
