Down Memory Lane - Common Sergeant

Down Memory Lane
The Common Sergeant (Athyma perius perius)

The Common Sergeant, one of the species of the genus Athyma, was recorded as extant in Singapore by the early authors. However, there have been no reliable sightings of this species for the past four decades and is believed to be no longer found in Singapore. Featuring the typical black-and-white markings of the genus, the Common Sergeant is distinguished by the forewing cell streak being divided into four portions. The orange underside has a characteristic series of prominent black post discal spots.

The caterpillars of the Common Sergeant feeds on host plants like Glochidion and Phyllanthus, both of which can still be found in Singapore. It is not known why the species has disappeared from Singapore. There are currently five other species of the genus Athyma extant in Singapore. Was the Common Sergeant's preferred habitat wiped out? Will it be seen back here again one day? Or will it remain only in our memories and is gone forever from Singapore?

Butterflies Galore! : Yamfly

Butterflies Galore!
The Yamfly (Loxura atymnus fuconius)

This brightly coloured Lycaenid is one of two species of butterflies currently known from Singapore, whose caterpillars feed on the young shoots of the forest "weed" Smilax bracteata (although there is still some debate as to whether this plant should be called Smilax setosa.) Whilst it has been recorded on some species of Dioscoreacea (Yam) in other countries in the region, the caterpillars in Singapore appear to prefer the invasive, non-native Smilax vine.

The Yamfly is not uncommon, and is quite widespread in distribution across Singapore, but mainly in areas where the caterpillar host plants are found nearby. This shot of a pristine Yamfly perched on a leaf, was taken by ButterflyCircle member Nelson Ong recently at the Dairy Farm Nature Park.

Butterflies Galore! : Bigg's Brownie

Butterflies Galore!
The Bigg's Brownie (Miletus biggsii biggsii)

The Bigg's Brownie is a species of butterfly that belong to the subfamily Miletinae. The caterpillars are considered "carnivorous" as they feed on other insects - primarily coccids, mealy bugs, aphids or ant larvae. The early stages of this butterfly also have a symbiotic relationship with ants. The caterpillars get protection from the ants in return for sweet secretions often referred to as "honeydew" from their bodies.

The Bigg's Brownie is often seen in the vicinity of ants like shown in this shot. As the ants are known to "farm" the aphids, mealy bugs and coccids for their secretions, the butterfly seeks out these locations to lay her eggs so that the caterpillars can feed on the aphids. This shot was taken by ButterflyCircle member Mark Wong in the forested nature reserves recently.

Butterflies Galore! : Fluffy Tit

Butterflies Galore!
The Fluffy Tit (Zeltus amasa maximinianus)

This long-tailed Lycaenid, or Hairstreak, is moderately common and widespread in distribution. It can be found in urban parks and gardens as well as in the sanctuary of Singapore's forested nature reserves. It can fly quite rapidly amongst the treetops but comes down to the forest floor to puddle occasionally. In the nature reserves it likes to feed on the flowers of the Bandicoot Cherry (Leea indica).

Males are regularly observed to puddle at moist sandbanks in the nature reserves. This individual was shot puddling by ButterflyCircle member Chng CK at the Dairy Farm Nature Park recently. Note the long white twirling tails and the shorter pair along the vein beside it. There is a characteristic prominent rounded black spot at the base of space 7 on the hindwing.

Festival of Biodiversity 2013

ButterflyCircle @ Festival of Biodiversity 2013
VivoCity - 13 & 14 Jul 2013


ButterflyCircle at the Festival of Biodiversity 2013!

After last year's successful Festival of Biodiversity held at the Singapore Botanic Gardens from 26-27 May 2012, NParks and the Biodiversity Roundtable started planning for this year's Festival. After some discussions, the preference was to hold the Festival at a more public venue to encourage more Singaporeans and residents of Singapore to appreciate the diverse biodiversity that can be found on this little island.

At the SBG, a large number of the visitors were already nature lovers, and "converting the converted" was perceived to be limiting the outreach and educational emphasis of the Festival. Hence this time around, the suggested venue for the 2013 Festival would be in a shopping mall, and specifically to reach out to the weekend crowds and families and to showcase what Singapore has, in terms of its amazing biodiversity.

The Festival of Biodiversity (FOB) is an annual event organized by the National Parks Board in collaboration with the Biodiversity Roundtable. The inaugural festival was first held in May 2012. The FOB an event to celebrate Singapore’s natural heritage to bring about greater awareness of the rich biodiversity in Singapore.

FOB 2013 was held at the atrium of VivoCity, Singapore's largest shopping mall. The FOB display area was located at the Central Court B, which was amply lit by natural daylighting via a skylight above the display area. As both the venue and the display set-up were sponsored by corporate benefactors, the location and area for this year's FOB was more compact with an integrated exhibition concept, rather than like the previous year's booth concept.

Overview of the display area of FOB 2013 at VivoCity's Central Court B

The display area was divided into three main sections featuring urban biodiversity, marine habitats and terrestrial habitats. The groups handling the marine exhibits and museum specimens took centre stage with their interesting offerings, especially to the ordinary laymen visitors. The rest of the groups had their opportunity to feature their respective groups' activities and work via videos and slide shows on the 40" flat screen monitors.

The event was graced by President Tony Tan (he was also the Guest of Honour last year). This year's FOB also saw the launch of the book "Living in a Garden - The Greening of Singapore" - a celebration of 50 years of greening in our City in a Garden.

At the same event, we also saw the issue of "Our City in a Garden" stamps and first day cover. ButterflyCircle's Horace Tan's Spotted Blue Crow caterpillar was also featured on one of the stamps in the series. Look carefully at the 80 cent stamp below and see if you can spot the caterpillar.

ButterflyCircle members were out in full support of the FOB 2013. The group also contributed to a video clip about BC and our activities. The video, directed and produced by ButterflyCircle member CJ Huang, showcased an amazing array of BC's photos, activities and contributions to the conservation of butterflies in Singapore.

Also featuring their respective videos and slide shows were groups like the Tampines-Changkat Butterfly group, Nature Photographic Society (S), NParks, Republic Polytechnic, Raffles Museum of Biodiversity and others. As the weekend public visitors streamed in to VivoCity, all the nature volunteers and groups who were at the display area were kept busy, explaining to the public and helping to create a greater awareness of Singapore's biodiversity.

BC members ended our morning with a sumptuous lunch at one of the Chinese restaurants at VivoCity. It was an enjoyable time for everyone, who made the effort to get out there on a Saturday morning to support the FOB and also BC. It was also a proud moment for everyone to view the videoclip featuring BC's high quality work. Veteran BC member Sunny Chir even brought his grandchildren to pave the way and nurture future BC members!

Down Memory Lane - Chocolate Tiger

Down Memory Lane : Gone Forever?
The Chocolate Tiger (Danaus melaneus sinopion)

This relatively large Danainae, the Chocolate Tiger (Parantica melaneus sinopion) is common in Malaysia, particularly at higher elevations like the hill resorts at Fraser's Hill and Penang Hill. Often, they fly in the company of other Danainae, feeding on wild flowers. The Chocolate Tiger has a slow and unhurried flight but can be skittish if approached too quickly.

It was recorded from Singapore by the early authors like W.A. Fleming but has not been seen for a long time. Like many of the Danainae, the caterpillar host plant is probably one of the not uncommon lactiferous plants (probably from the Asclepiaceae family) that still grow in our forests. The wings of the Chocolate Tiger are bluish grey with the veins and wing borders coloured a dark chocolate brown. The abdomen of the butterfly is light orange-brown and prominent when it is in flight. Will it be seen back here again one day? Or will it remain only in our memories and is gone forever from Singapore?

Butterflies Galore! : Five Bar Swordtail

Butterflies Galore!

The Five Bar Swordtail (Pathysa antiphates itamputi)

This fast-flying "swallowtail" butterfly is always a crowd-pleaser whenever it appears. Usually easier to approach and photograph when it is puddling, the Five Bar Swordtail is unique in the sense that its long tails taper off in a sword-like shape. The colours on the undersides of the wings are also an attractive blend of black, white, yellow and green.

This well-executed shot of the Five Bar Swordtail was taken by ButterflyCircle member Loke PF last weekend at the Dairy Farm Nature Park. The puddling butterfly's colours are brought out effectively on a clear background of pastel green. Note also the little bubble of pee at the tip of the butterfly's abdomen.
