Scientific Name: Chalybeothemis fluviatilis
Common Name: Green-eyed Percher
I was always fascinated by this species of dragonfly due to it’s shinning green eyes. It is an uncommon and localise species which are found in exposed weedy banks of streams, rivers and near the banks of reservoirs. I have seen this species at just three locations; 1) near the banks of MacRitchie Reservoir; 2) at the big pond at Kent Ridge Park; and 3) at the open pond at Bukit Timah Nature Reserve.
This male was taken at the last location. A pleasant surprise for me as this was the first time I have seen this species at the location.
Scientific Name: Oligoaeschna amata (Fӧrster, 1903)
Common Name: Paddle-tail
Oligoaeschna amata is a very rare species of dragonfly which has occasionally been sighted at the Central Catchment Nature Reserve. It is thought that this species was believed to be extinct in Singapore but recent sightings has proved to be otherwise.
This species of dragonfly seems to inhabit wooded swampy forests and is crepuscular. It rests by day in the dense undergrowth and forages before dusk. Female has long racket-like appendages which often lost through breakage.
A recent trip to the CCNR has awarded me with a glimpse of the elusive female resting in the undergrowth of the secondary forest.
This species is known to exist in Borneo. It appears to be absent from Peninsular Malaysia.
Family: Chlorocyphidae (Jewels)
Scientific Name: Libellago lineata
Common Name: Golden Gem
Golden Gem is a very attractive damselfly and is locally rare in Singapore. The male has extensive golden-yellow markings on the thorax and abdominal segments. It has dark iridescence spot on the tip of the forewing. It also has white legs which it displays during fighting with rival males. The female is slightly bigger and more robust.
This species can be found in just two to three locations in Singapore. It has been found at a large sandy-bottom stream in the western part of Singapore and at a remote corner of the reservoir in the Central Catchment Nature Reserve. It has also been seen at a stream inside the forest of the MacRitchie Reservoir.
These are sub-adult males which has yet to develop the shade of golden colour of the adult males.
Adult males display their full glory and are always ready to fight for territories and to mate with the females.
These are sub-adult females. They are stouter with thicker abdomen.
Fully-grown females are greenish with black markings. They often hide in the corners and away from the breeding spots. They only appear at the right time for mating.

Scientific Name: Diplacodes trivialis
Common Name: Blue Percher
This small species of dragonfly is one of the more common dragonfly that can be found in Singapore. It frequents open marshes in disturbed areas, wastelands, and fringes of the forest reserves. This species sometimes wonder far from the water source.
I found this species to be quite common along the bicycle track near Bukit Timah Nature Reserve, at the open grassland at Chestnut Avenue, at the old Kanji Nature trail, and even at the Garden by the Bay.
The male is blue in colour and as it matures, pruinose develops, and it becomes powdery blue in colour. The abdomen segment 9 to 10 is black and the anal appendages is white. It has blue eyes.
Female has pale green yellowish markings on it’s black body. The eyes are brownish on top and yellow below. Young females are more yellowish in colour.
This species often flies horizontally and very near to the ground. They are skittish and sensitive to any movements in the surrounding. Not an easy species to approach.
