The Upper Seletar Reservoir Park is a gem of a place for insect and macro photographers. Rare forest butterflies, damselflies, spiders, flies and other critters can be found along the forest edges if you spent time looking for them. The rows of Syzygium zeylanicum when in bloom are a magnet for a host of butterflies and moths that are rarely seen outside the forest. Landscape planting of the Leea indica, Leea rubra and Ixoras provided added food sources for them.

Spending a morning combing the forest edges early this week with Richard White, Laurence Leong and Lee Yue Teng opened a whole new world to the insect and understorey life for me. Star finds include a Scorpion, two Agamid lizards, cockroach, spider, a fly and some butts but surprisingly no damselflies.
Asian Forest Scorpion Heterometrus sp, a rare find in the daytime. Venom is not known to be lethal. Richard found it crawling along the tarmac and promptly brought it back to the forest.First time seeing the underside of a forest cockroach. The six dots around the mouth is interesting.The migrant Chocolate Albatross is still around. A total of six were counted at the park.Long-legged Fly is a species of the Condylostylus genus. Feeds on aphids and other small insects.The Common Three Ring used to be common here but is hard to find these days.Subterranean Termites on the move. Harvestmen or Daddy Long Legs. Over 6,000 species of this species have been discovered worldwide.Black-beared Flying Lizard. Diurnal and noctunal, it inhabits the trees in mature forests.Earless Agamid. This was found on the adjacent tree to the flying lizard. Aboral and diurnal, it is largely confined to the Central Forest. This is the only photo with showing the blue iris of the male.

Butterfly watching is somewhat different from birding but just as absorbing. For one thing they are smaller and harder to identify in the field. The best part I like about it is not having to wake up at the break of dawn, as the butterflies are active much later in the morning. Lim Kim Keang, veteran birder and a keen butterfly watcher first got me interested in butterflies. On some slow birding days I got a chance to do some butterfly watching with him and also learn from other members of the Butterfly and Insect Group.
Mango Hawk Moth, about half the size of my palm, found by Yong Yik Shih
Recently I was fascinated with the forest butterflies that were seen at our reservoir parks. Some of the rarer ones are found at the host plants inside the forests, which is not very accessible. But they will move out when the plants along the forest edges flower.
I have been always wanting to get this Humming Bird Moth on my sensors. They were also attracted to the nectar of the Sycygium flowers.
Early this month a row of Syzygium spp at the Upper Seletar Reservoir Park bloomed. I was lucky to see a proliferation of rare Awls, Snow Flats and Skippers that were not normally seen outside the forests. To top it all we had a rare mango moth to end the season. I had a total of eleven lifers thanks to the help from so many butterfly experts I met there. Here are some of the butterflies and insects we managed to get on our sensors during those few mornings.
This Robber fFy was found inside the trails of the Seletar Forest.
Common Snow Flat is a sun loving butterfly and likes to bask with opened wings
Brown Awls were out in force on all the days when we were there.
You can only see small white specks zipping around. They are the Snow Flats. The Ultra has more markings at the base of the hind wings.
Malayan Lascar is very similar to the Common Lascar but are less common. Do comes down to the ground to feed.
Tree Flitter, a small skipper is not easily seen. Spotted by Chan Yiu Nam.
Pale Mottle likes underside of leaves that are infested with Asphids. Like the ants they are attracted to the secretions of the Asphids.
Common Posy looks like the Branded Imperial but has more black Stripes on its hind wings. Often returns to the same sun lit spot.
Darky Plushblue was the rarest butt seen during the past few days, thanks to the Kim Keang’s sharp eyes
A low perspective of a uncommon Cruiser. Loves to feed on excrement and dead animals.
This fairly large Skipper, the Hoary Palmer was really friendly and stayed around for all of us to get our shots. The heighten White hind wings are good id features.
The Purple Duke is the only butterfly in its genus found here and Malaysia. When disturbed it will zipped away and hide at the underside of leaves with folded wings.
Unfortunately this is not the White-tipped Baron that Lena Chow saw the day before. It is a male Form Gardineri Baron.
Malayan Snow Flat is rarer than the look alike Ultra. This was pointed out to me by by Khew Sin Khoon.
The White Banded Awl should have a more colorful name. When the hind wings catch the sunlight, you can see the purplish sheen on it like in this photo.
