Scientific Name: Heliaeschna uninervulata
Common Name: Lesser Night Hawker
I was at Pulau Ubin in early June 2015 when I accidentally bumped into a pretty “large” Aeshnid-like dragonfly resting at the forested vegetation near to the main road. The time was about 4 plus in the afternoon and apparently this male individual was not very active then.
After a couple of shots, it becomes obvious to me that this is a male H. uninervulata (my third sighting of this species in Singapore). The unique features of this species is the single cross vein on the wings and the incision-shaped anal appendages (for males).
This species is very rare in Singapore and the sighting at Pulau Ubin could be a new record found at the location.
Scientific Name: Orthetrum glaucum
Common Name: Common Blue Skimmer
A common species that can be easily found near degraded forested habitats within and outside nature reserves in Singapore. I have seen this species at many locations especially within the forest fringes at Bukit Timah Nature Reserve, Chestnut Avenue Forest, Upper Seletar Reservoir Park and many other places.
They can be found at or near water sources such as ditches, ponds, small streams and rivers, resting on boulders, tree branches and leaves. Sometimes they are found far away from any water bodies especially at fringes of the forests, and wastelands.
The male has bluish green eyes. The thorax is generally dark blue and abdomen is lighter blue with the last two segments darken. Younger male has a lighter brownish colour. Female is light brown with greyish green eyes. Both aged male and female developed pruinosed over their bodies which are covered with powdery blue colouration.
