The Chequered LancerPlastingia naga and the Yellow Chequered LancerPlastingia pellonia are the only two Plastingia species in Singapore. Both are forest species and like to rest in the shade of the undergrowth with folded wings. The only time they open their wings is to bask in the sunshine when puddling. The former is uncommon and the latter is rarer.
I have yet to see the Yellow Chequered Lancer but have encountered the Chequered Lancer on two occasions at Dairy Farm Nature Park and Upper Seletar Reservoir Park. Unfortunately they were too quick for me to get any photographs.
Over the year, there were several sightings of the Chequered Lancer along the forest trails at MacRitchie Reservoir, which I missed. So it was third time lucky when I came upon a tame individual resting by the side of the trail on 1st Sept 2022.
What made this encounter special was getting photos of the top view and the side views of their full wing spread. I cannot find any photos of the Yellow Chequered Lancer upper wings but I read that both look similar with the white spots of the Yellow Chequered Lancer appearing larger than the Chequered Lancer. Whereas the underside is very different. The markings of the Yellow Chequered Lancer are yellow while the Chequered Lancer markings are white, giving it a black and white chequered look.
The grass and reed beds by the sides of our inland reservoirs is a micro ecosystem by itself. It is teeming with insect life, mainly dragonflies, damselflies, grasshopper and some butterflies. I have been visiting the wetlands around our freshwater reservoirs mainly to photograph the odonatas.
Fong and his brother were photographing what looked like a Saint Andrew’s Cross SpiderArgiope versicolor, wrapping up a motionless Common Scarlet dragonfly that got caught in its web.
All my past sightings of the St. Andrew’s Cross Spiders were by the forest edges and along the jungle trails in our nature reserves. This is the first time I seen it with its web across the long grasses by the water edge. How and why did this spider move out of the forest to a very different habitat was a puzzle to me. Could it be that there is a lack of insects or looking at a change of diet?
I did some checking in Biodiversity of Singapore and found that this is the Yellow-Silver St. Andrew’s Cross Spider, Argiope cantenulata, ( Marcus Ng), also known as a Grass Cross Spider. This orb-weaver spider is found from India to the Philippines and Papua New Guinea.
It preys mainly on dragonflies that hunt and breed in this habitat. Once it flew into its web, the spider quickly immobilizes it by spinning and wrapping the prey with its web. It then injects digestive enzymes into the victim to break down its body tissues. The spider sucks up the pre-digested tissues and repeats the process again. It seems to be locally common with most of the sightings along the edges of reservoirs. Apparently they are quite common in the padi fields in Malaysia.
Birders to the montane forests of northern Borneo pay more attention to the Whitehead trinity of Broadbill, Trogon and Spiderhunter than the other bird species named after another ornithologist Coenraad Jacob Temminck.
The three Whiteheads are rarer which made their quest more rewarding. John Whitehead, an English explorer and naturalist was the first documented person to scale Mount Kinabalu. He also was the first collector of the Whitehead Broadbill and had 10 bird species named after him.
Coenraad Temminck, a well known Dutch ornithologist and zoologist was the first director of the Leiden Museum of Natural History. He inherited a large collection of bird specimens from his father who was a good friend of Francois Levailant, another well known French ornithologist and wildlife collector.
There are 20 birds and 14 mammal species named after Temminck. During our trip to Tras Madi, Sabah in June, I added the Temminck’s Babbler,Pellorneum pyrrhogenys, to my list of two species i.e. Malaysian Eared Nightjar,Eurostopodus temminckii and Temminck’s Sunbird, Aethopya temmickii. I missed Temminck’s Stint at Sungei Balang by an hour.
The Temminck’s Babbler is found in the sub montane forests of Borneo and Java. There are four subspecies with the ones in Borneo having a grey face instead of the brown-grey face of the Javan subspecies.
The Temminck’s Sunbird on the other hand can be found in the lower montane and lowland forests of Peninsular Malaysia, West Sumatra and Central Borneo. The nearest population to Singapore is at the Panti Bird Sanctuary but not often seen. It looks like the Crimson Sunbird with its reddish head and back but the Temminck’s has a silvery white belly and a red upper tail compared to the greyish underbelly and dark tail.

In 1986, Philip Chew found many rare plants and orchids in a regenerated forest at the heart of the Trus Madi range. Together with his brother Jimmy and friend Tam, they pooled their retirement funds and proceeds from sale of their homes to set up the Tras Madi Conservation Area. Their aim was to preserve the biodiversity of the 747 square meters of the conservation area. Their efforts paid off when it was designated as Class 1 forest reserve. In 2006 they were given an operation permit to set up a camp inside the area. The Trus Madi Entomology Camp better known as the Borneo Jungle Girl Camp was born.
The present day camp was a far cry from the first camp which was a single tent. You will be shown videos of how they dragged each cabin on logs from Apin Apin to the site.
Today the Entomology Camp is well known globally as the center for the study of insects and moths in Borneo. Against all odds they had created ” something out of nothing”. Unfortunately Philip passed away and Jimmy is left to carry on with his legacy today.
We ( Wilson Leung and his wife Theresa) were indeed privileged to be able to experience the magic of this world in June 2022 with the help of David Tseu, a Sabah based wildlife guide. Here are some of the more colorful moths and fascinating insects that we saw during our 4 days stay. Credit to iNaturalist for some of the identifications which are subject to confirmation from the experts and notes from Wikipedia.
We photographed 21 butterfly species during our 4 days of birding at the Trus Madi Conservation Area, Gunung Alab Substation and Mahua Waterfalls, all part of the Crocker Range of Sabah, from 14 t0 17 June 2022. One endemic and two sub endemic species.
Here are some of the butterflies that are not found or gone extinct in Singapore. Will appreciate any corrections on the identity and notes.
The Crocker Range has remained my last birding destination in Sabah for some time. When news that the elusive Bulwer’s Pheasant had been seen at the montane hill forests at Trus Madi Forest Reserve, I started to do some serious planning and waited for the borders to open.
I got in touch with David Tseu, a long time nature guide based in Kota Kinabalu, through the recommendation of friends.
A 4 days trip was arranged and together with Wilson Leung and his wife Theresa Ng, a first time birder, we scooted to Kota Kinabalu on the 13 June 2022.
Wilson arranged an overnight stay at the Holiday Inn Express where the ceiling to floor windows look out to a forested hillside. A Blue-throated Bee-eater and flocks of Asian Glossy Starlings were ticked off. A stay at KK will not be complete without a seafood dinner. We chose the Crab House at Sabah Suria and shared two large crabs and grouper soup for RM 230.
David met us the next morning in his spacious 4WD and drove towards Tambunan with a break for breakfast at Gunung Alab Motel, a popular rest stop. The road was winding but thankfully the morning traffic was light.
We reached the Borneo Girl Jungle Camp inside Trus Madi Conservation Area in time for lunch after surviving a 90 mins bone shaking ride on the bumpy gravel logging track for the last part of the journey. Jimmy Chew and his partners have slowly expanded the camp, providing nature lovers with clean, comfortable but basic rooms. The nights are cold as we are at 1,400 meter asl. The big surprise for me was the food here. It was the best Hakka/ Cantonese cooking I ever had in all my jungle birding trips. Sweet and sour kampong chicken for dinner and double boiled Shiitake Mushroom soup for the next evening.
The weather forecast was for thunderstorms for the whole of our stay, but thank god the weatherman was wrong. We had only 2 hours of heavy downpour during our entire stay. Best of all, our birding was not disrupted by the usual morning and evening misty foggy weather.
We did all the birding along the old logging track near the camp. It was easy pleasant birding amidst the cool montane forest. Many of the endemic species that can be seen at Mt. Kinabalu Park are found here. A playful flock of Brown Fulvetta, part of a mini bird wave, greeted us the first morning. The endemic Charlotte’s Bulbul was preening away. It looks exactly like the Peninsular lowland Buff-vented Bulbul as it was a recent split. Theresa alerted us to a pair of Rhinoceros Hornbills flying across the valley. It was quite a sight! The Buah Cherry trees and the hibiscus plants at the camp are frequently visited by the Bornean Leafbirds, Red-throated Barbets, Bornean Bulbuls and Temminck’s Sunbirds. Always a treat to be able to photograph such rare birds without too much hard work.
There are several hides along the trail not far from the camp. We spent both mornings and afternoons in two of them. We were extremely lucky to see and photograph all the species we came to see.
Top of the list was the majestic Bulwer’s Pheasant, a most sought after endemic that had eluded many birdwatchers for a long time. A lone male showed up on the third afternoon. These are most probably the first photos of this pheasant taken in the wild by any group from Singapore. Next for me was the Bornean Banded Pitta and the Dayak’s Jungle Flycatcher. The bonus were a family flock of 14 Crested Partridges and the Temminck’s Babblers. Lifers for all of us.
Besides the birds, there were many interesting mammals to keep a lookout for. David’s acute sense of the jungle got us the endemic Red-leaf Langur, Whitehead’s Squirrels and Masked Palm Civet.
The ever changing views of drifting clouds across the mountain ranges and green valleys are just breathtaking. Sunrise and sunsets were even more spectacular. Unfortunately the nights were overcast and we missed seeing the Milky Way.
The day’s action did not end after dinner. We were not prepared for the hundreds of moths and insects when we went to check out the four insect screens set up on a ridge near the camp. None of us have ever seen so many moths, beetles, cicadas and other weird and wonderful insects in our life. From the tiniest to palm size, the moths came in all shapes and colors. We had a great time perfecting our macro photography on them. We could not get enough of this and spent all three nights hoping to see some rare lunar moths, but none showed up.
We left the camp after breakfast on the last morning and made our way back to the Gunung Alab Substation for the Red-breasted and Crimson-Headed partridges, both endemics. They proved to be more co-operative and came out within the first hour. The damp bamboo forest is their preferred habitat.
A family of Snowy-browed Flycatchers also took up residence here and it was nice to see the different plumages of the juveniles and females.
There was enough time to pay a visit to the Mahua Waterfalls about 20 km from Tambunan to do some last minute butterfly photography Some of the endemic butterflies including the Rajah Brooke and the Green Dragons can be found there. Wilson and Theresa booked an overnight stay at the resort outside the waterfalls and we bade them goodbye as David drove me to the airport for my evening flight home.
It had been a very successful and lucky trip, a memorable one as well, We got all our target birds, thanks to David’s local knowledge and experience. We recorded a total of 58 birds ( 14 endemics), 21 butterflies ( 2 endemics), 8 mammals ( 4 endemics), 1 reptile and hundreds of moths and insect species. We were blessed with good weather for all the four days. A big thank you to the staff at the camp for the delicious food and help.

Even though it was a birding trip to the Crocker Range of Sabah to look for the Bulwer’s Pheasant at Trus Madi Conservation Area, we were surprised to find so many insects during our few days there. Most were moths that were attracted by the lights at night. But many of the strange and wonderful insects were seen during the daytime when the birds were not active.
There are many pygmy grasshoppers that mimic dead leaves, but there only two Oriental Macropterous in Asia. The Oxyphyllum found in India and Pakistan and the Paraphyllum in Borneo. David Tseu our guide knew exactly which rock face to find the P. antennatum on our way to the Trus Madi Camp. They are small and blend in well with the color of the rock surfaces. Their curved brown body looks like a dead leaf. We counted about half a dozen of them all males according to David. The females have an elongated tail.
We would have missed this on the track if not for David’s sharp eyes. The Pill Millipede, Glomeris sp. one of the largest millipede around, but short bodied. It exhibits the Pangolin way of defense by rolling into a ball when threatened. When left alone it will slowly open up, check the surrounding before fully extending to its full length.
This Tacua speciosa Cicada is one of the most colorful and also one of the loudest. Its call is unmistakable and can be heard for long distances. We missed the chance to photograph it close up and had to be contended with this back view shot.
Lantern bugs of the Fulgoridae plant hopper family does not emit light but they are colorful. This is the common Pyrops sultana white body species with an orange snort, which is part of its inflated head. Wilson found this on the track near our camp.
I don’t know how David can spot such a small insect like this weevil resting on a thin blade of grass. This is the Larinus Weevil looking a bit like a shining beetle with a big nose.
The menacing looking Giant Three-horned Rhinoceros Beetle, Chalcosoma moellenkampi, is one of the more common beetles that came to the screens at night. A favourite with beetle collectors, it is found only in Borneo. This is the male as the females do not have horns.
Bee flies are colorful. This species Migya tantalus, was seen taking minerals at the Mahua Waterfalls area
Also on the way to the waterfalls beneath the dark forest canopy, David picked up this tiny jewel of a beetle on a leaf by the path. Borisb identified it as a Aplosonyx sp in iNaturalist. It looks like the A. monticola in another posting on iNaturalist by Gan Cheong Weei taken at the same location on 10 Jan 2019. There is not much information on this species online.
A nice find to end our trip.
With Wilson Leung, Theresa Ng and David Tseu. 14-17 June 2022.
The Trus Madi Conservation Area at the Crocker Range in Sabah is well known among insect and moth lovers as the place to go and see the hundreds of insects of the tropical montane hill forests. The Trus Madi Entomology Camp, better known as the Borneo Girl Jungle Camp was set up in the conservation area primarily to study the insect life there.
Insect screens with special lights to attract the insects were erected at the both sides of a ridge near the camp. On most nights, these screens were swamped with insects, mainly moths of all shapes and sizes, cicadas, beetles, cricket and wasps. April I was told is the peak month.
Every morning the resident Pig-tailed Macaque will make its way to the ridge and pick out the biggest and juiciest cicadas that are still on the screen. It will tear away the wings before biting off its head and then the body. These fruit eating monkeys would not pass off a chance of tasty snack that is rich in proteins as well. We saw some squirrels around but did not see them taking any of the insects.
During the night, another opportunistic raider was on standby. The Barred Eagle-Owl waits patiently at the near-by tree for some of the larger moths and cicadas to fly by before swooping down to pick it up. These insects will supplement their usual diet of rodents and squirrels.
When dawn breaks, the rest of the insectivorous birds would gather at the trees on both side of the ridge to start their day with easy pickings. The Ashy Drongos and the White-throated Fantails will sally out for the smaller flying moths. Flocks of the endemic Chestnut-crested Yuhinas will flush out the rest of the insects for a quick meal. While the Black-bellied Malkohas and the Red-bearded Bee-eaters wait for the larger ones. Even the small tailorbirds were able to pick and choose their food from the buffet in front of them.
This feasting must be a ritual for these birds every morning. Free and easy food in the cool montane air. For the bird watchers and photographers, it is an opportunity not to be missed.
With Wilson Leung, Theresa Ng and David Tseu ( Nature guide).
One of the heart stopping birding moments I remembered was hearing the calls of the Great Argus Pheasant behind my back and seeing them at its “dancing ground” in the Johor Forests way back in the 1997. Last week I experienced the same heart thumping moment when a male Bulwer’s Pheasant, Lophura bulweri, appeared right in front of our hide at the Trus Madi montane forest of the Crocker Range in Sabah.
David Tseu, a nature lover and experienced bird guide who have been studying the habits of this pheasant, made this possible. I came to know about this place and this Bulwer’s last year when Datuk Peter Pang posted photos of it on his facebook page. Due to the pandemic and closed borders, all the nature parks in Sabah were closed to oversea visitors. The wildlife here had their forests for themselves for over two years. When Sabah opened up in in May, Dr. Chan Kai Soon from Ipoh was the first to visit and posted photos of this pheasant. This was enough for me to book my flights to Kota Kinabalu, the nearest jumping off city ( a 4 hours drive) to the Borneo Jungle Girl Camp at Trus Madi. I asked Wilson Leung and his wife Theresa to join me as he has been wanting to go birding with me for some time. I had to thank Eric Tan for the intro to David Tseu and where to bird.
The pheasant was not seen since Dr. Chan’s visit more than a month back, but David was somewhat confident that it is still around. It was a no show on the first afternoon. We had only one more afternoon left and at 4.30 pm a family of the Crested Partridges, Rollulus rouloul, came up at the edges of the stake-out. This was a great sign as the Bulwer’s Pheasant is known to move with them for protection. Sure enough, shortly after David whispered to me ” It is here”.
I could hardly focus my camera on the pheasant standing just a few meters away from us as my hands were shaking. We cannot believe our luck, being so closed to such a stunning looking pheasant, its dark purple speckled body contrasting with its snow white tail. I was savoring every seconds of its presence until it got spooked and ran away. Fortunately it came back after it sensed that it was safe and we had another round of less frantic shooting.
It is locally common in the remote montane hill forest of northern Borneo. But you will need to be at the right area, lots of patience and a dose of good luck to see one as their numbers are low. Since 1998, there were only 19 entries in ebirds with records from Poring, Danum Valley, Maliau Basin and most recently at Trus Madi. It was mission accomplished for my number one target for the trip, thanks to David’s local knowledge and birding skills.
I am glad that the site is under proper management by the owners of the camp, a group of passionate nature lovers and insect experts whose main aim is protect the habitat and the wildlife in it for the younger generations to come.

Of Endemic Crab, Night Frog, Unique Spider and Rare Butterflies.
The quiet Upper Seletar Reservoir Park is well known for its forest bird, butterfly and insect life. But being adjacent to the Nee Soon Swamp Forest, there is also a surprising diversed freshwater aquatic life as well.
On one late August morning, I was delighted to find a nocturnal swamp crab in one of the drains here following Art Toh’s FB post. It turned out to be the Reticulated Swamp Crab (Paratherphusa retculata), one of our three endemic crabs found in Singapore. It was only discovered in 1989 inside the Nee Soon Swamp forest as its secretive and nocturnal habits have kept it hidden all these years.
Nearby a Malesian Frog Limnonectes malesianus betrayed its well-hidden nook by jumping away. Luckily for us it stayed motionless at it’s next resting spot. According to Nick Baker all the local Malesian Frogs have this black marking on the external ear drum. Along the same drain, there was a small reddish brown catfish about 10 cm long. I missed getting a shot as It was quick to swim away and hide under the leave litter.
Further up the road, on a tree trunk that I used to go pass umpteen times, a family of SpottedCoinSpidersHerennia multipuncta, were busy bringing up another new generation of these unique spiders. They are small and live on the tree trunks all their life, using camouflage as their survival against predators. Every successful generation is a celebration for this species as the male can only mate once in their lifetime.
Two rare butterflies came out this morning. The small Malay Dartlet that can be confused with the Common Dartlet and the male White-tipped Baron which I though was the more common Common Baron. Both are my lifers.
Besides these, there were some uncommon butterflies like the Full Stop Swift, Hoary Palmer, Palm Bob and the Darky Plushblue, the last staying on the same leaf for hours.
Our hope is that there will be no developments at this park to destroy the precious biodiversity. Plans should be put in place to enhance it. There should be no trespasses inside the primary forests so as not to disturb the wildlife there.
I like to thank so many of my friends who helped to find and showed me these creatures, without which I would not have been able to photograph and post them here.
