Butterflies Galore! : Indigo Flash

Butterflies Galore!
The Indigo Flash (Rapala varuna orseis)



The Indigo Flash is a moderately rare species that has a rather wide distribution, turning up in forested areas as well as urban parks and gardens in Singapore. Both sexes of this species feature deep blue or bluish-green uppersides. It is a fast flyer and sometimes flies and hides on the underside of a leaf when disturbed. On hot sunny days, or in the early morning hours, it can be seen sunbathing with its wings opened flat on the top surfaces of foliage.

The male is indigo blue above and unmarked, whilst the female is a steely-blue and similarly unmarked. The underside is dark brown with broad post-discal bands. There is a strong purple wash on the underside of both wings - more prominently in the male than in the female. This female, shot last weekend at Pulau Ubin's Butterfly Hill, appeared to be a newly-eclosed individual and was cooperative for awhile during the early morning hours after a rainstorm.

Butterfly of the Month - July 2014

Butterfly of the Month - July 2014
The Peacock Pansy (Junonia almana javana)



As we move past the halfway mark of the year 2014, we take a look back at the first half of the year with a some trepidation about the safety of air travel these days. Perhaps statistics still show that one is more likely to be killed in a car accident than on a plane, but whenever a whole plane goes down with most or all of its passengers, the news often carries a greater collective impact and shock.




Even as the mysterious disappearance of Malaysian Airlines Flight MH 370 still remains unsolved, the shooting down of yet another Malaysian Airlines Boeing 777 over Ukrainian airspace shocked the world. This time around, 298 passengers and aircrew perished. As the world was still coming to terms with another Malaysian Airlines plane lost, another plane, an Air Algerie flight carrying about 118 passengers and crew went down in bad weather and crashed over Mali.



As if to round up a week of bad news, Taiwan's TransAsia Airways ATR-72 turboprop aircraft ploughed into a residential area in Penghu killing 48 people. This time around, there were 10 survivors, as the plane was apparently in trouble during bad weather, before the crash. The TransAsia crash was the third worldwide in the space of just eight days, capping a disastrous week for the aviation industry.



We mark a moment of respect and contemplation, as we can never fully comprehend the grief of the surviving relative and families of those who perished in the air crashes. In some cases, entire families were wiped out. As we ponder about the safety of air travel these days, life still goes on. Perhaps the recent three cases were just a coincidence and an aberration in air travel worldwide? No one can say for sure.





Over in the region, as the summer season is in full swing, Singapore is experiencing hotter and drier weather. A short 4-day weekend trip by a small group of ButterflyCircle members across the causeway to Ipoh for a butterfly photography outing also yielded comparatively poor results. Somehow, butterfly activity seems to be rather low in our favourite places with much lower numbers and diversity than our past visits.



This month, we feature a common urban butterfly, the Peacock Pansy (Junonia almana javana). This bright and cheery orange-coloured butterfly is one of four related Pansy species found in Singapore. The Peacock Pansy is widely distributed, but mainly found in urban parks and gardens, and along the sunlit fringes of Singapore's nature reserves.



It is a sunny-weather species, and often found on hot bright days, fluttering amongst the low shrubbery and flowers. It adopts a flap-glide flight characteristic but can be skittish and alert to any movements or approach by a photographer. When feeding on flowers, it can be approached more easily.



The Peacock Pansy can often be observed sunbathing with its wings opened flat to show its bright orange coloured uppersides. When the weather cools down or when there is cloud cover, the butterfly often perches with its wings folded upright, displaying its muted undersides where it can rest amongst the dried foliage with a relatively effective camouflage to avoid predators.




The bright orange upperside of the Peacock Pansy features prominent white-centred ocelli which may have given its English common name "Peacock". Both the fore and hindwings have prominent ocelli with the eyespot on the hindwing larger and resembling an "eye". The underside is much paler and eyespots are smaller and appear more lightly marked.



The life history of the Peacock Pansy has been documented here on the blog, where it has been bred on Ruellia repens a common urban "weed". It is also likely that the caterpillar of the Peacock Pansy is able to feed on other plants as well.

Butterflies Galore! : Narrow Spark

Butterflies Galore!
The Narrow Spark (Sinthusa nasaka amba)



When it was discovered back in 1995, it was a new record for Singapore. The early authors' checklists did not include this species as extant in Singapore, although it can be found in Malaysia. The Narrow Spark is moderately rare, and is quite local in distribution, often spotted in a few select localities in the forested nature reserves in Singapore. They often lurk in heavily shaded forest, and is skittish.

The underside of the butterfly resembles a Common Tit. However the Narrow Spark is much smaller and possesses a pair of filamentous white tipped tails. The upperside of the male is a deep rich ultramarine blue. This species has been successfully bred on Eurya acuminata and the detailed documentation can be found here.

Life History of the Cycad Blue

Life History of the Cycad Blue (Chilades pandava pandava)


Butterfly Biodata:
Genus: Chilades Moore, 1881
Species: pandava Horsfield, 1829
Subspecies: pandava Horsfield, 1829
Wingspan of Adult Butterfly: 22-26mm
Caterpillar Local Host Plants: Cycas revoluta (Cycadaceae, common name: Sago Palm), Cycas rumphii (Cycadaceae).





Physical Description of Adult Butterfly:
On the upperside, the male is blue with thin black borders on both wings and it has a black tornal spot on the hindwing. The female is in paler blue with broad borders on the forewing and it has a series of submarginal spots on the hindwing, of which the spot in space 2 is crowned in orange. On the underside, both sexes are pale greyish brown. Both wings have the usual submarginal, marginal and post-discal series of spots and cell-end bars flanked with white. In the hindwing, there is a black spot in the cell, two black spots in space 7, another one just below vein 1a and orange-crowned tornal spots in spaces 1b and 2. There is a white-tipped filamentous tail at vein 2 in the hindwing.




Field Observations:
Cycad Blue is common in Singapore. The adults are usually observed flying in the vicinity of its host plant, the ornamental Sago Palm which can be found in many gardens in commercial, recreational and private residential areas. They are viewed as a pest by gardeners as their presence usually leaves the prized ornamental plants without new growth. The adults visits flowers for nectar and have the habit of sunbathing with open wings in sunny condition.

Butterflies Galore! : Quaker

Butterflies Galore!
The Quaker (Neopithecops zalmora zalmora)



This small butterfly is usually associated with the shaded understorey of the forested areas in Singapore's nature reserves. Seldom seen in open urban gardens and parks, the Quaker is usually encountered fluttering restlessly amongst the low shrubbery in forested areas. Occasionally, males are encountered puddling with other butterflies on damp streambanks in the forest.

The Quaker has the characteristic large black spot at the costa of underside of the hindwing. The upperside is predominantly brown and unmarked in the male, and sometimes with a white patch on the forewing of the female.

Festival of Biodiversity 2014!

ButterflyCircle @ Festival of Biodiversity 2014!
VivoCity : 12-13 July 2014


ButterflyCircle members at FOB 2014 with CEO/NParks, Mr Kenneth Er and Minister of State, Mr Desmond Lee

This year, the 3rd Festival of Biodiversity returned to VivoCity mall after last year's well-visited event, also held at Singapore's largest shopping mall. Occupying a larger footprint than the previous year's FOB, the 2014 festival promised to be an even bigger showcase of Singapore's rich and diverse biodiversity.



With all the participating members of the Biodiversity Roundtable and several new groups added, each partner group had an individual booth exhibiting its members' work and featuring its contributions and playing its part in the showcasing and conservation efforts of Singapore's biodiversity.


ButterflyCircle's booth at the FOB2014

This year, ButterflyCircle decided to do a collage of our members' work on three large A0 boards, which also described the objectives of the group and its activities. There were also smaller boards that provided additional snippets of information about Singapore's butterflies. The work of collating the photos and putting together the boards was again ably done by our enthusiastic lady member, Huang CJ, assisted by the intrepid twins, Mark and Anthony. Once again, CJ has to be congratulated for assembling the awesome presentation boards that was informative, educational as well as pleasing to the eye.


ButterflyCircle early-bird members helping to set up the booth

The day started very early at 7:15am when ButterflyCircle members CJ, Eng Chuan, Anthony, Jerome and me reached VivoCity. The booths had already been set up the night before, and everything was ready to receive the boards. After a quick discussion the group set about Velcro-ing the boards and sticking them up on the panels. It was efficiently put up and many hands made light work of setting up our booth. Everyone had a sumptuous breakfast at Yakun Kaya Toast after that!

The Festival of Biodiversity is an annual event organised by the National Parks Board (NParks) that showcases Singapore’s impressive and unique array of island biodiversity. This event celebrates Singapore’s natural heritage and in doing so, hopes to bring about greater awareness of the biodiversity that Singapore has. FOB 2014 had special thematic focus, which highlighted Pulau Ubin, Singapore's island biodiversity and conservation efforts. This year also saw an emphasis on our marine biodiversity.

At about 11am, the Guest of Honour, President Tony Tan arrived, and was greeted by members of the biodiversity community. The Master of Ceremonies welcomed everyone and invited the Minister of State for National Development, Mr Desmond Lee to deliver his opening address. This year, the highlight of the FOB was the announcement that Singapore will establish its first ever marine park! The Sisters' Islands Marine Park, which will span about 40 hectares around Sisters' Islands and along the western reefs of both St John's Island and Pulau Tekukor, will serve as a platform for outreach, educational, conservation and research activities related to our native marine biodiversity.

The rest of the day was a flurry of activities as members of the public visited our booth and asked questions about butterflies. We had our Field Guide for sale to members of the public and we also took the opportunity to sell Dr Laurence Kirton's recently-launched Butterflies of Peninsular Malaysia, Singapore and Thailand. Dr Tan Wee Kiat, the CEO of Gardens by the Bay, picked up two copies of our field guide too! Thanks, Dr Tan. :)
