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.

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.
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.
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.
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.
