Butterfly Photography at Our Local Parks - Telok Blangah Hill Park

Butterfly Photography at Our Local Parks
Featuring : Telok Blangah Hill Park


The Terrace Garden which leads up to the highest point of Telok Blangah Hill Park

In our earlier blogpost on the Southern Ridges Parks, we explored the 47 Ha Kent Ridge Park. Starting from west and moving towards east, the Southern Ridges comprises Kent Ridge Park, Hort Park, Telok Blangah Hill Park and Mount Faber Park. All the four parks are interconnected via walkways and overhead bridges. This weekend, we take a look at the next elevated park, Telok Blangah Hill Park.


An overview of Telok Blangah Hill Park which is connected to Hort Park at the western end at Alexandra Road, and to Mount Faber at the eastern end at Henderson Road

A view along the elevated Forest Walk, which connects Alexandra Arch to Telok Blangah Hill Park.

Telok Blangah Hill Park is bounded by Alexandra Road on its western boundary, and Henderson Road on its eastern boundary. This elongated park is about 34 Hectares in area, and covered with lush greenery over most of its area. It is connected to the Hort Park via the Alexandra Arch overhead bridge at its western boundary. A visitor entering from this end of the Park will trek the Forest Walk – a 1.3-kilometre-long elevated metal walkway that links Hort Park to Telok Blangah Hill Park.


Below the elevated Forest Walk is the Earth Trail.

A certain locations, the Earth Trail is connected to the elevated Forest Walk via staircases

Both the Earth Trail and Forest Walk end at the little metal shelter which then leads you onto Telok Blangah Green road

An alternative route along the same direction is the Earth Trail that brings you closer to the forest understorey. The Earth Trail is below the elevated Forest Walk and connects to the elevated walk at certain places via staircases. Both trails will lead a visitor to Telok Blangah Green. At the start of the Forest Walk is a shelter at which you can take a quick rest before proceeding to the other parts of this hill park.

Be prepared for lots of staircases and steps at Telok Blangah Hill Park!

The entrance to the Terrace Garden

Telok Blangah Green winds around the hillock which overlooks the Terrace Garden. The Terrace Garden consists of a series of semi-circular terraces situated at the top of the park. The top of this hillock is the highest point of the park and from here, you will be able to enjoy a breath-taking 360-degree view of Singapore.

Alkaff Mansion and more steps!

The forecourt at Alkaff Mansion

Walking along Telok Blangah Green will take you past the historic Alkaff Mansion, an elegant colonial bungalow built by a family of Arab Traders, which used to host grand parties for the social elite and who's who in 19th century Singapore. Situated on top of a knoll with a commanding view of the lush greenery around, Alkaff Mansion is now an F&B outlet today.


Some of the red-brick paths winding through the forested areas in the park

As you continue to walk towards the east, you will pass a public rest room on the left, and the Therapeutic Garden on the right. The lush greenery all around the garden creates a restorative environment to engage the senses and to uplift both mental and emotional well-being while serving as complementary habitat for native biodiversity. Walk towards the Therapeutic Garden and take a short detour downhill towards the Stream Garden which brings you to the foot of the hill and the main road Telok Blangah Heights.

And more steps!

Back up at the Therapeutic Garden, and on the left of Telok Blangah Green is a hilly patch of lush forested area with a network of quiet paths complete with stone tables and seats and a shelter from the elements. There are the occasional butterfly surprises around this area, and one should look carefully at the shrubbery that may attract some rarities.

If you stay on the main trails, there are ample signages

One of the older trails that lead you to the hillock that connects to Mount Faber Park.

On the right side is Car Park 1, and another network of paths winding around the greenery, leading to another knoll which is connected to the Henderson Bridge. There is a shelter and seats at this hilltop area where one can take a short rest and a cold drink from the vending machine before crossing the distinctive Henderson Waves overhead bridge to Mount Faber Park.  This forested hillock was also the location where the body of Huang Na was found after her tragic murder back in 2004.



Butterflies of Telok Blangah Hill Park

As far as butterflies are concerned, the Southern Ridges is a location where occasional rare species may appear. This is related to one of the habits of "hill topping" by butterflies - whereby many species, particularly the males, indulge in the activity of choosing their favourite perches and patrol the area for eligible females.  The list of butterflies featured here is not exhaustive.



Two examples of butterflies that are normally found in the forested nature reserves, but can be spotted at Telok Blangah Hill Park.

Over the years, some of the species that have been observed at Telok Blangah Hill Park include some of the rarest Lycaenidae species that have been observed in Singapore. As some of the vegetation have evolved over the years, certain species that have been spotted between 2000 and 2010 are no longer seen today. Interestingly, some forest-dependent species like the Branded Imperial and Malayan Lascar were "regulars" at TBHP in the past.


The Colour Sergeant was once found quite commonly at the grounds of Alkaff Mansion.  It is no longer seen there today.

At the grounds of the Alkaff Mansion, there once were a few host plants of the Colour Sergeant growing at the periphery of the forecourt. I recall that we often found the caterpillars of the Colour Sergeant on this host. Today, these plants have not survived and the species is rarely seen at this location.



Three Spot Grass Yellows eclosing on their host plant, Albizia

The common urban species are found at TBHP, and interestingly, three species of the Eurema or Grass Yellows, have been observed around the park. There was a time when the Albizia trees (Paraserianthes moluccana) had large congregations of the Three Spot Grass Yellow (Eurema blanda snelleni) breeding on them. The Common Grass Yellow (E. hecabe contubernalis) and the Chocolate Grass Yellow (E. sari sodalis) are also spotted here.



Look out for the distinctive dragon-headed Plain Nawab caterpillars on the Red Saga shrubs

If you look amongst the low shrubs of the Red Saga, there are often caterpillars of the Plain Nawab (Polyura hebe plautus) feeding on the leaflets of this common tree. The adults are often frolicking at tree top level, flying rapidly from one perch to another, and returning repeatedly to their favourite perches.


The Malayan Plum Judy was first recorded from the Southern Ridges



Examples of the Miletinae found at Telok Blangah Hill Park

This park was one of the first places where the Malayan Plum Judy (Abisara saturata kausambioides) was spotted. It can still be observed hopping from leaf to leaf in recent years. At least four species of the Miletinae are regularly observed at TBHP, the most often seen is the Biggs Brownwing (Miletus biggsii biggsii) flying restlessly amongst the shrubbery. The Apefly, Blue Brownwing and Pale Mottle have also been spotted here.


The rare Silver Royal was feeding at the flower of Syzygium sp. at Telok Blangah Hill Park when it was sighted in 2005


The very rare White Fourline Blue was observed at Telok Blangah Hill Park for a period of about a month in 2009.  It can no longer be found there and has not been seen since.

Amongst the Lycaenidae recorded here is the very rare Silver Royal, which was photographed whilst feeding on the flowers of a Syzygium tree where it was first recorded as a re-discovery in 2005. Another very rare Lycaenidae, the White Fourline Blue (Nacaduba angusta kerriana) was first observed at TBHP. Subsequent to that sighting in 2009, where it was documented as a re-discovery, a female was observed ovipositing and its life history successfully recorded on the host plant Entada spiralis. However, it has not been seen since that short period in 2009.



Various other Line Blues from the genus Nacaduba are often sighted at Telok Blangah Hill Park

The other confusing lookalike Sixline and Fourline Blues can also be found here, usually frolicking on bright sunny days. They fly rapidly, and then select a perch onto which to land and they have a unique habit of flattening themselves to the angle of the sun to maximise their exposure to the warm sunshine.




A variety of skippers observed at Telok Blangah Hill Park

Amongst the Hesperiidae found at TBHP are the various Palm Darts, Common Redeye, Chequered Lancer, Plain Banded Awl and the Orange Awlet (where its caterpillar host plant, Arthrophyllum diversifolium, is commonly found at TBHP). The variety of caterpillar host plants that can be found at TBHP supports these species. Some examples are Spatholobus ferrugineus, Caryota mitis, Cocos nucifera and various grasses and bamboos.

All in all, the butterfly diversity at TBHP is above average. However, the park cannot be considered as an ideal butterfly-shooting location for beginners due to its topography and vegetation - some areas of which are not easily accessible. As nectaring plants are not as widespread, it is challenging to photograph butterflies that are actively flying about. Nevertheless, it is a good place to do butterfly-watching, due to its variety of habitats and environments.

Bukit Panjang Butterfly Garden

Bukit Panjang Butterfly Garden
Community Planting Day 


The Bukit Panjang community and volunteers with Mayor Dr Teo Ho Pin at the Bukit Panjang Butterfly Garden

Located in the north-west of Singapore, Bukit Panjang, formerly called Zhenghua, is home to about 140,000 residents. Pre-independence, Bukit Panjang consisted of mainly rural settlements and agricultural farming. Over the decades, Bukit Panjang has developed from a largely agricultural and industrial area to a highly urbanised and self-contained town, as kampung folks and farmers were re-housed in new Housing and Development (HDB) flats. Despite these changes, much of the area’s terrain and greenery have been preserved to form a unique blend of urban and rural space. The area retains its strong connection to nature through the neighbouring Bukit Timah Nature Reserve to the south and the Central Catchment Nature Reserve to the east, both of which contain rain forests.

In recent years, the National Parks Board's (NParks) Community in Bloom programme worked with the residents to bring back the kampung spirit in the form of community gardens. Residents and volunteers are encouraged to set up gardens where they can bring back their past activities as well as bond with their neighbours and friends living around the precinct. Bukit Panjang constituency is home to more than 11 community gardens specialising in edibles and medicinal herbs. The Bukit Panjang community gardens have a large variety of vegetables and fruits which are grown by community gardeners who work together to keep the kampung and gotong royong spirit alive in modern Singapore.



Sussie Ketit, who started the original Bukit Panjang Butterfly Garden in 2013

Tucked in between two of the community gardens along Bukit Panjang Road, a small butterfly garden was set up in 2013. Championed by grassroots activist Sussie Ketit and her team of volunteers, the butterfly garden led a low profile existence with about 10-15 species of butterflies regularly seen at the garden.



Site visit to the Bukit Panjang Butterfly Garden with Mayor Dr Teo in March 2017

This year, Sussie approached Foo JL of Seletar Country Club Butterfly Group for his assistance to expand the Bukit Panjang Butterfly Garden (BPBG). A site visit amongst our group of butterfly enthusiasts and the Mayor of North West Community Development Council (CDC), Dr Teo Ho Pin in March this year, initiated plans for the expansion of the original BPBG.



Planter beds all ready for the plants 

The group, ably led by Foo and his volunteers, Sussie and Sebastian Chia, and landscape contractor Tian HM set out to plan BPBG 2.0. The Town Council and a group of volunteer gardeners chipped in to help as well. The plans took shape as the planter beds were constructed and topsoil added. Butterfly host and nectaring plants were prepared and readied for the planting day planned for Jun 2017.




Foo JL and Cheng Khim at the morning briefing and show-and-tell to the volunteers

The Bukit Panjang Butterfly Garden 2.0 Community Planting Day started early on Saturday 3 June. Foo JL and Cheng Khim were on hand to brief the community volunteers and gardeners about butterfly plants and the caterpillars of butterflies that feed on them. Cheng Khim helped to brief the non-English speaking participants and everyone enjoyed the show-and-tell session with live caterpillars and information about plants that attract butterflies.






Working hard at planting butterfly plants!

The group then went to the various planting beds that were already prepared with many butterfly host and nectaring plants. A final briefing by Tian on how to properly dig a hole and place the plants gently into the soil, everyone was raring to go. Armed with spades, shovels and changkuls, the volunteers, young and young-at-heart, helped to fill the planters with their selected plants.




Young and the young-at-heart digging and putting in their favourite plants with tender loving care

Despite the hot and humid morning, everyone had a lot of fun digging and planting the various host and nectaring plants. The rather ad-hoc placement of the plants is typical of a natural butterfly garden habitat, where the landscape design allows for a more natural look, rather than a horticultural display of organised and manicured planting.




Mayor Dr Teo Ho Pin joins in the fun

Mayor Dr Teo joined in the planting exercise and he energetically planted a Red Tree Bush (Leea rubra), a butterfly nectaring plant, right in the centre of the "VIP" planter bed. The local gardening community ladies also joined in to help Mayor Teo make sure that the plants were well watered. Foo JL brought some butterflies for Mayor Teo to release, to mark the event.


Making sure the plants are well watered

The morning ended with a nice buffet (like all things Singaporean, there will always be good food at such gatherings), generously sponsored by Sussie. After the hard work, everyone was in high spirits and looking forward excitedly to more butterflies at BPBG in the coming months.


The proximity of Bukit Panjang Butterfly Garden to the Nature Reserve and park connectors makes it a potentially good location to attract more species to its location

The BPBG is situated along Bukit Panjang Road next to Block 213/214 Petir Road. The site is quite ideal, as it is linked to the Pang Sua and Zhenghua Park Connector network that links to biodiversity-rich areas like Dairy Farm Nature Park and further south, the Bukit Timah Nature Reserve. Its immediate proximity to the forests of the Central Catchment Nature Reserves is also advantageous, as a concentration of nectaring plants may attract some forest butterflies along the edge of the reserves to fly over to feed.



The next generation.  A bunch of eggs and caterpillars of the Three Spot Grass Yellow (Eurema blanda snelleni) found at the BPBG.  Very soon these pretty yellow butterflies will be fluttering around at the garden!

And so BPBG has been planted and good to go. It has 'pupated', waiting for the plants to grow, and for the flowers to bloom and attract butterflies. Its metamorphosis has started, and we will wait for a couple of months to see the fruits of the community's labour. Hopefully, we can encourage more butterfly enthusiasts to enjoy butterflies and conserve the environment that is conducive for our winged jewels to survive for our future generations to enjoy them.
