Scientific Name: Risiophlebia dohrni
Common Name: Potbellied Elf
Listed as endangered in the Singapore Red Data Book, Potbellied Elf is one of the most rare species of dragonflies that can still be found in the Central Catchment Nature Reserve. It is very small and is often found near or in shaded forest pools and nearby streams and vegetation.
In July, I have encountered two females and a single male in the Nature Reserve.
I feel both happy and excited to see this species again in the Nature Reserve and hope it continues to survive in our forests.
Scientific Name: Agriocnemis minima
Common Name: NA
Agriocnemis minima is a tiny and unrecorded species of damselfly that is only recently being discovered in Singapore. I have taken shots of males and young and aged females at a freshwater swamp in the Western part of Singapore.
The adult female has eluded me until very recently when I bumped into this female. After doing some research on the internet, it became apparent to me that this individual should be the adult female form of this species. It is very rare and I have only seen one individual of this form.
The eyes are brown on top and green below. It has yellow pterostigmata, and has yellow stripes on the synthorax. The sides of the thorax and abdomen are green and the dorsal side of the abdomen is black.
This species prefer to be in the open, grassy areas at the edge of the flooded wetland. It is probably the tiniest species of damselfly in Singapore with the abdomen plus appendages measuring just 14.5mm.
Scientific Name: Merogomphus femoralis
Common Name: Malayan Spineleg
This species is very rare in Singapore and was first recorded in Nee Soon Swamp Forest in 2007 and 2008. There was a single male specimen recorded from Peninsular Malaysia on 1921.
I found the female individual at a heavily shaded forest trial at NSSF in Jun 2013. It was found resting on a fallen tree trunk on the trail when I first seen it. Shortly afterwards, it flew and rested on top of a leaf slightly above my eye level and facing away from my view. I managed to took a few quick shots before it flew even more higher up to the canopy and disappeared soon after.
This is a medium-sized gomphid with well-separated green eyes. It has greenish yellow stripes on the sides of the thorax. The abdomen segment has five horizontal yellowish stripes. Another distinguishing feature is the white superior appendages and the long hing legs.
About a week later when I was at the exact spot where I seen the first female, I saw another individual (or was it the same female?), resting on the same tree. This individual was also very skittish and does not allowed me to take more than a few shots.
I have compared the photos of these two individuals with the one published by Mr. Tang and found it to be very similar. My conclusion of this species is that it is very skittish, and it could well be found deep in the Singapore forests.
Scientific Name: Leptogomphus risi
Common Name: Ris’Clubtail
On May 03, 2014, I chanced upon a very rare gomphid, the very elusive leptogomphus risi, at the small stream at Dairy Farm Nature Reserve. This is a male specimen which so far, has only been recorded once in the forest at Rifle Range Road on 7th of March 2004, mentioned in Tang’s book of Singapore Dragonflies.
The male was resting on top of a fern plant very close to the stream. It is a small stream with slow flowing running water, deep in the heavily shaded forest in the Nature Reserves. This was my first sighting of a gomphid species at that part of the nature reserves.
It was regretted that I only have a few long distance shots of this male due to the fact that I only have my 100mm macro lens on hand and the dragonfly was actually perching very near to the stream while I was standing on an elevated ground of at least 2-3 metres away from the stream. After having taken a few long distance shots, I decided to go down to the stream for a closer look but on my way down, my movements frightened the dragonfly and it disappeared soon after.
I hope this dragonfly is still at the vicinity and I will try my luck again next time.
