I usually look out for dragonflies at the reservoir edge next to the SICC golf course. I think this predominantly blue damselfly is Pseudagrion microcephalum, a common species in many parks and nature reserves.

It was a later afternoon, this Chestnut-capped Laughing Thrush was resting high on the tree.
I cannot identify the next two skippers. There were shot at the foot of Bukit Fraser on a rather sunny and hot afternoon. The first shot looks like a Notocrypta species.
My first shot of a mating Lady Bug. There were quite a few of them foraging on leaf surfaces. This intimate pair didn't seem to be shy about their behaviour.
A rather large bug appeared to be wearing a armoured shield around its body, I guess this is a kind of Sting Bug. Apart from these insects, I have shot many species of moths - will post these shots when I have the time to process the pictures.

Chocolate Albatross (Appias lyncida vasava) was in great numbers that they could obstruct our view of getting a clear shot on other puddling butterflies.
The grayish white ground colour of this lycaenid with speckled wings is likely to be a Malayan Sunbeam (Curetis santana malayica). When it is in flight, its prominent and striking apical orange patches on the uppersides will definitely tell you where it has gone to.
The White Four-line Blue (Nacaduba angusta kerriana) can also be found in Singapore though it is rather elusive and rare. It was re-discovered in late 2008 and within a short period of time, its life history was successfully recorded (see BC's blog). There were at least two species of small black-and-white lycaenids fluttering in the area but I managed to capture only this Banded Blue Pierrot (Discolampa ethion thalimar ) which was rather skittish and did not stay on the ground for long.This small lycaenid is Common Line-Blue (Prosotas nora superdates) which is fond on puddling on moist objects, hard or soft. A rather common species in Singapore as well that explains why many of us did not really have an interest in chasing it. I took a few shots hoping that it would be other species.
Ciliate Blue (Anthene emolus goberus) is characterised by the little black dot on the hindwing dorsum - this is another common species most of us would not chase for a shot if we have other choices. A not-so-pristine Common Tit (Hypolycana erylus teatus) appeared while I was chasing and getting a shot of the Malayan Sunbeam.
According to Khew and a shot of the upperside of this brown skipper, it is Pithauria stramineipennis. Many of them were zipping and puddling along the riverbanks. This one looks like a Dark Banded Ace (Halpe ormenes vilasina) Initially I thought this was a Chestnut Bob (Iambrix salsala salsala) because of size and the wing shape. However, the forewing orange subapical patch and the absence of white spots on the hindwing suggest that it was another species. I guess it is Idmon obliquans obliquans.

We were really trilled by the number of butterflies puddling on the river banks - this is just one of the puddling sites.I shall feature all the species that I have managed to photograph in two parts.
|This is a Striped Jay (Graphium chironides malayanum) - I guess the two curved black strips on the hindwing beneath give its common name.|
We can see the four black bars on the the upperside of the forewings.
Rajah Brook's Birdwing (Troides brookiana albescens ) is a typical example of the sexual dimorphism in terms of puddling behaviour. So far, I have not seen a female puddling while the male often congregate and puddled in a group. I tried to isolate one of them and took an open-wing shot while others puddling with wings flapping frantically.
The next 3 species are from the Nymphalidae family. The Indian Yellow Nawab (Polyura jalysus jalysus ) was intoxicated by the nutrients in the damp soil. It stayed at this position for more than 20 minutes, allowing us to take as many shots as we like.
A common species in the Malaysia forests, though the Common Nawab (Polyura athamas athamas) looks quite similar to the Indian Yellow Nawab, we can easily tell the differences.
This is a very pristine male Jewel Nawab (Polyura delphis concha ) who came down a few times to tease us before it really got intoxicated by the nutrients-rich sandy ground where he stayed quite a while for all of us to take a few shots.
In my next post, I will continue sharing more puddling butterflies from three other families.
