Dragonfly (25) - Brachydiplax Chalybea

Family : Libellulidae
Common Name : Blue Dasher
Status : Common
Location : Singapore Botanical Gardens, Rifle Range Nature Trail, Segar Road

A relatively small-sized species commonly found in ponds. Males are blue in colour with dark patches while females are brown in colour. Female is less common than male. I have seen the female only once. By the way, I have initially thought that this is a Aethriamanta Gracilis. Both look very similar although B. Chalybea is slightly bigger in size.

Dragonfly (24) - Neurothemis Fluctuans

Family : Neurothemis fluctuans
Common Name : Common Parasol
Status : Very common
Location : Almost anywhere in Singapore where there are bushes near ponds, streams, lake, reservoirs, etc.

This is easily one of the most common dragonfly species that you can find in Singapore. They are so common that most of the photographers, me included, would give it a miss when seeing them.

Dragonfly (23) - Rhyothemis Triangularis

Family : Libellulidae
Common Name : Sapphire Flutterer
Status : Uncommon
Location : Chestnut Ave, Venus Drive, Eng Neo Ave

Rhyothemis Triangularis is an unmistakable species.  The male has distinct dark metallic blue colour on its wings. Female is similar to the male but the base of its wings are darker.  This uncommon male species was first sighted at Venus Drive but I gave it a miss as I had not started collecting Odonata at that time.  My 2nd sighting was at Chestnut Ave.   I only managed a few record shots before it flew away.

My 3rd sighting was at Eng Neo Ave but unfortunately, I still did not get nice images of it. I have yet to meet the female. In my opinion, it is best to take from a dorsal view to show its beautiful wings. I shall do that next time.

My 4th sighting of this species was at Jurong Woods II.  Unfortunately, it was too sensitive to me and I could not get close to it.  I was bitten by a water leeches while chasing for it!  My 5th meeting was at Lornie Trail on 25 Aug 2010 and this time I managed to set a reasonable dorsal view showing the beautiful wings of this dragonfly.

Dragonfly (22) - Rhyothemis Obsolescens

Family : Libellulidae
Common Name : Bronze Flutterer
Status : Uncommon
Location : Chestnut Ave, Rifle Range Nature Trail

This species can be easily identified by its bronze wings and dark marking. Both male and female are similar in appearance. They like to perch under direct sunlight. I have only seen this dragonfly in an open marshes near Chestnut Avenue. Unfortunately, before I could get a better shot of it, the place is now under redevelopment  for private residential purposes.

My 2nd sighting of this species was at Rifle Range Nature Trail.  I am glad to capture some improvement shots of it.

A relatively large dragonfly species. Quite commonly found near ponds.

They are usually quite skittish and not easy to photograph.
