The Plain Tiger (Danaus chrysippus chrysippus)

During the butterfly surveys in the mid-90's the Plain Tiger was rarely seen in Singapore. Although observed once in a while, it was by no means common at all, and infrequently seen in parks and gardens. Today, with the cultivation of its caterpillar host plants, Asclepias currasivica and Calotropis gigantea at public parks, schools' eco-gardens, park connectors and so on, the Plain Tiger is a commonly seen butterfly.

This female Plain Tiger feeding on the flower of the Cosmos sp. was shot by ButterflyCircle member Sunny Chir at Gardens by the Bay a few days ago. The species can be seen fluttering around the flowering plants at Gardens by the Bay, and in particular towards the Meadow area of Bay South Garden where its caterpillar host plant is grown.

Random Gallery - Peacock Royal

The Peacock Royal (Tajuria cippus maxentius)

The Peacock Royal is one of a number of butterfly species that feeds on the parasitic mistletoe, Dendrophthoe pentandra. In Singapore, this common parasitic plant is the host for the caterpillars of the Great Imperial (Lycaenidae), Painted Jezebel (Pieridae) and Green Baron (Nymphalidae). Whilst parasitic plants tend to eventually destroy the host on which it grows, the damage done (if any) takes a relatively long time, especially when the parasitic plant is on a large tree. To conserve these butterfly species, it is hence important that Dendrophthoe pentandra is allowed to proliferate naturally without any human intervention and let nature take its course. Besides butterflies, the plant is also popular with birds which go after its fruits. This is how the parasitic plant is spread - through the droppings of the birds when the birds fly to other trees and expel the seeds after digesting the fruits of the plant.

This pristine female Peacock Royal was shot last weekend at Gardens by the Bay by ButterflyCircle member Koh Cher Hern. The butterfly is a fast flyer but can often be found feeding on flowering plants like the Ixora spp. The male of the Peacock Royal features an attractive royal blue on the upperside of its wings. Females are light blue. The underside is a pale grey with dark streaks whilst the hindwing bears a pair of white tipped tails.

Life History of the Chocolate Grass Yellow

Life History of the Chocolate Grass Yellow (Eurema sari sodalis)

Butterfly Biodata:
Genus: Eurema Hübner, 1819
Species: sari Horsfield, 1829
Subspecies: sodalis Moore, 1886
Wingspan of Adult Butterfly: 35-40mm
Caterpillar Local Host Plant: Archidendron jiringa (Fabaceae, common name: Greater Grasshopper Tree, Petai Belalang).

Physical Description of Adult Butterfly:

Above, the wings are deep lemon-yellow, each with a black border which is regularly scalloped and deeply excavated between veins 2 and 4 in the forewing. Underneath, the wings are yellow with freckled brown spots. There is one cell spot on the forewing which has its apex entirely in dark brown. Males have a brand lying along the cubital vein on the forewing underside.

Field Observations of Butterfly Behaviour:

Chocolate Grass Yellow is common in both nature reserves and urban parks in Singapore. The adults can be readily seen fluttering tirelessly in these areas. They are easily confused with other Grass Yellow spp. while in flight, but their distinctive brown forewing apical area immediately set them apart when they come to a perch. They regularly visit flowers for nectar and puddle on wet grounds for minerals.

Random Gallery - Tawny Coster

The Tawny Coster (Acraea violae)

After settling down in Singapore since 2006, the Tawny Coster has continued to spread southwards into Indonesia. The species continues to thrive successfully in Singapore, as it is able to adapt to several host plants, mainly of the Passifloraceae family. Its favourite caterpillar host plant is still Passiflora foetida a "weed" that grows rapidly in cleared areas and wastelands. As the female lays anything from 20-50 eggs at one go, the species is statistically more successful in terms of its survival, as long as its host plants are found commonly.

Over at Gardens by the Bay, the Tawny Coster has been observed in the areas where there are wildflowers and the less manicured parts of the gardens. Here, ButterflyCircle member Sunny Chir shot this pristine male Tawny Coster feeding on the flower of the Coat Button (Tridax procumbens), balancing itself quite comfortably on the rigid wildflower as its proboscis probes the flower for nectar.

The Gram Blue (Euchrysops cnejus cnejus)

I've always wondered how the Latin name of this butterfly is pronounced! The Gram Blue, as we prefer to know it by for simplicity, is a moderately common species and may occasionally be abundant where its caterpillar host plants, Pueraria phaseoloides and Macroptilium laythroides are found. Both plants are creepers that can be found in cleared wastelands and tend to stay hugging the ground.

The species is now also found at Gardens by the Bay as evidenced by this rather pristine female perched open-winged on some grasses. This individual was shot by ButterflyCircle member Billy Oh last Sunday during the survey.

The Pea Blue (Lampides boeticus)

The Pea Blue is a butterfly that can be found at Gardens by the Bay. This Lycaenid flies fast and erratic on hot sunny days, but can also be spotted resting amongst the shrubbery in the early morning hours, and also in the vicinity of its caterpillar host plants, Crotalaria retusa and Crotalaria mucronata - both "Pea Plants".

In this shot, taken on Sunday at Gardens by the Bay, ButterflyCircle member Nelson Ong managed to capture a portrait of a Pea Blue feeding on the flower of the Coat Button plant (Tridax procumbens). Considered a weed, the Coat Button is a flowering plant from the Asteraceae family (or Daisies). The plant is believed to have medicinal properties and used in traditional Indian medicine as an anticoagulant, hair tonic, antifungal and insect repellent, in bronchial catarrh, diarrhoea, dysentery, and for healing wounds.

The Pale Grass Blue (Zizeeria maha serica)

This species was only discovered in Singapore some time in the early 2000's and was identified as the Pale Grass Blue by the late Col John Eliot when detailed photographs were sent to the region's foremost butterfly guru in England, just a few months before he passed on. The Pale Grass Blue has since become a permanent resident in Singapore and is found mainly in urban parks and gardens. The butterfly often flies in the company of the two other "Grass Blues" - The Lesser Grass Blue and the Pygmy Grass Blue, on hot sunny days.

This shot of a Pale Grass Blue was taken by ButterflyCircle member Anthony Wong at the Fragile Forest area of Gardens by the Bay last Sunday. Not commonly known to many visitors, Gardens by the Bay is also home to many species of urban butterflies and on a butterfly survey last weekend, ButterflyCircle members counted at least 32 species of butterflies.
