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.
