Sapphire Flutterer, an uncommon dragonfly, tend to inhabit ponds, streams, and reservoirs. So far, I have only encountered this species a couple of times, at MacRitchie Reservoir.
This species is very distinctive and unmistakeable in appearance. Males and females are similar. Eyes reddish brown on top and dark brown below. Thorax and abdomen are dark metallic blue. Most distinctive are a pair of wings that have a broad and deep purplish blue patches. Males tend to be brighter and females more darker in colour.

Common Name: Yellow-Barred Flutterer
Yellow-Barred Flutterer is a very widespread and common dragonfly in Singapore, and other South East Asia regions. It is commonly found at marshy swampland, ponds, reservoirs, and open grasslands.
This species is unmistakeable. Males and females look similar. The thorax and abdomen are dark, and the hindwing base has a very distinctive barred yellow and dark brown pattern.
A few years ago, I have often seen this species flying in swarms especially at the vicinity of Bukit Timah Nature Reserves, but this scene is more and more uncommon nowadays. They are sun-loving species and it is a sight to see them gather in swarms, gliding in the air and feeding small insects.
Scientific Name: Vestalis amethystina
Common Name: Common Flashwing
This is a relatively large damselfly, the total body length is about 50-56mm and commonly found near forest streams at Central Catchment Nature Reserves and Bukit Timah Nature Reserves. So far, I have seen this species at MacRitchie reservoir -along the board walk, Upper Seletar Reservoir, Upper Pierce Reservoir, Chestnut Ave forest, and Dairy Farm Nature Reserves.
Males and females look quite alike, the main difference is their anal appendages. Both has metallic green body with very long and thin legs. It has a pair of transparent wings which show off a sparkling bluish purple iridescence from reflection from the light.
This species tend to occur on smaller streams in the primary forests.
Scientific Name: Acisoma panorpoides
Common Name: Trumpet Tail
This dragonfly is commonly found at open disturbed habitats including grassy swamps, edges of the reservoirs with short grassy vegetation, ponds, and drains. So far, I have seen this species at places like MacRitchie reservoir, Ang Mo Kio Town Garden West, and small streams at Central Nature reserves.
As it’s name suggest, this species is unmistakable by it’s unique shape of it’s abdomen. Male has light blue eyes and body. Female is similarly shaped and patterned, but the colour of the eyes and body is more greenish.
This dragonfly is quite small in size and very inconspicuous when they perched among grassy vegetation.
They are very aggressive dragonfly and will eat all kinds of smaller insects, including damselflies.
