Oligoaeschna foliacea is one species of Aeshnidae that is seldom seen by the dragonfly enthusiast as not only it is rare, but also it is crepuscular, which means it is active during dawn and dusk. During the day, it rests deep in the wooded swampy forests, normally hanging vertically on leaf or twig just above an observer’s eye level.
During one of my usual dragonfly trip to the North-Western part of Singapore’s nature reserve, I have the chance to witness a splendid male in it’s full adult coloration.
This is one of the most stunning species of dragonflies in my opinion. We are lucky that it can still be seen in Singapore. Wish that this species can continue to thrive in our nature reserves.
Scientific Name: Copera Vittata
Common Name: Variable Featherlegs
Copera Vittata is rare in Singapore and according to the book “Dragonflies of Singapore”, it was recorded in only two sites within the Western Catchment Areas. My specimen of this species was however, found at another location, inside the dense vegetation and near the mangrove swamps of Pulau Ubin.
I found several individuals, both males and females, and one mating couple, near the small drain that exits into the sea. It was heavily shaded and the sluggish channels was perfect environment for this species to thrive.
This species is slender and dainty. It has variegated pattern of greenish yellow maculation on the synthorax. Immature has pale whitish body, known as “Ghost form”.
Palua Ubin is the only site I have seen this species. I would say this is a very interesting looking species of damselfly due to it’s ghost form. I was especially fascinated by the eye’s colour and pattern. A must-see species for dragonfly enthusiasts.
Scientific Name: Copera marginipes
Common Name: Yellow Featherlegs
Yellow Featherlegs is a fairly common damselfly which inhibit small streams, sluggish and often muddy channels, swamps around forest edges. In Singapore, I have encounter this species at Chestnut forest, and the forest around Mandai and Kranji.
This species is easily recognizable. Male has dark thorax with yellow streaks. The legs are yellow and flatten and the last two abdominal segments including the anal appendages are white.
Female has duller white or yellow streaks and abdomens are black.
Both immature male and female have white bodies and they are called – the “Ghost Form”.
