Early stage of Tagiades gana gana (Large Snow Flat)


Tagiades gana gana (Large Snow Flat) is one of the commonest Flat found in Singapore & Peninsula Malaysia, and frequent the vicinities of forests.

In Singapore, this species feed on Dioscorea piscatorum, where the plant is wide spread from Peninsula Malaysia to Borneo. In Peninsula Malaysia, its also feeds on Dioscorea alata, D. glabra.

Early stage observation

Eggs are found singly on the upper surface of its host plant mature leaf, less than 1 m above group level. The larva make leaf shelter by cutting a small part of a leaf & folding it. The larva stays on the upperside of the shelter throughout 1 - 5 instar, even after changing the shelter when it grow bigger. Final instar larva reach about 35 mm in length. Pupation take place in the shelter, pupa length is about 22 mm. Pupa is greyish with pale orange-pink tint in color, and many dark brown spots. The pupa lacks the usual triangular white specks at the base & outer margin of forewing, make the identification easy.

Patial life history of Matapa druna

Matapa druna

The genus is represented from Sri Lanka and India to China, Sundaland, Philippines and Sulawesi. It's found in Malaysia but not Singapore.

The caterpilar is whitish, with orange head, and 2 black marking resembled eye. The host plant is bamboo sp. According to the earlier author, all the Matapa sp. are rare (except Matapa aria), all Matapa can be found in lowlands of Peninsula Malaysia.

The male of this species has an arcuate brand on the upperside forewing, which can be seen on the specimen below. The brand extending from the middle of vein 1b to below the base of space 3.

ID corrected as pointed out by Dr. Seow TL, previously recorded as Matapa cresta

Early stage of Danaus chrysippus chrysippus (Plain Tiger)

The last tiger of the series, I have not come across the early stage of the other 2 tigers yet - Danaus genutia genutia (Common Tiger) & Danaus melanippus hegesippus (Black Veined Tiger) yet. Should not be too difficult to find them, at least I know where to find Common Tiger.

Early stage of Black Rose (Pachliopta aristolochiae antiphus)

The Black rose -- this subspecies (Pachliopta aristolochiae antiphus) was not recorded by the earlier author or researchers in Peninsular Malaysia & Singapore.

According to the record, in Singapore, it was first sighted some time back in 1995 by Steven Neo, who captured a specimen at Venus Drive. It was an all-black specimen, without the white hindwing markings. The red spots and abdomen were quite typical of the Common Rose ssp asteris but smaller or fewer with a slightly different shape.

Starting from year 2004, this species become a more commonly found "Common" Rose species in Singapore and more sighting has been reported since then.

Simon Chan from NSS Butterfly Interest Group first highlighted in the Nature news in Mar 2007 that, the Black Rose could be the Bornean subspecies antiphus and not the usual asteris.

While I'm not too sure who make the final decision that it's indeed the subspecies antiphus, I did manage to take the opportunity to collect an egg of this Black Rose & breed it to adulthood.

Family: Aristolochiaceae
Species: Aristolochia tagala

Telicota colon stinga (Pale Palm Dart)

Telicota colon stinga (Pale Palm Dart) - latest re-discovery of Singapore butterfly

The genus Telicota is one of the challenging to identify and distinguish from the look-alike species in the group, and definitely not easy to identify from field shots. However, I'm pleased to announce the re-discovery of the Telicota colon stinga (Pale Palm Dart) and added it to the Singapore Butterfly observation list.

I bred this skipper 2 years back on Guinea Grass but not until recently, when I learnt how to dissect butterflies and make meaningful comparison. After careful investigations and seeking advice from Malaysia butterflies expert, Dr Laurence Kirton, it was confirmed that this skipper indeed a Telicota colon stinga.
