Another year has passed and we are well into the year 2022. This is the final weekend before the Lunar New Year starts on 1 Feb 2022. As the year of the Ox ends, the new year will welcome the next animal in the Chinese horoscope, the Black Water Tiger. Will it be a year when the world recovers successfully from the Covid pandemic that started two years ago? Only time will tell...

This month, we'll just jump straight to our Butterfly of the Month for January 2022 - the Little Maplet (Chersonesia peraka peraka). Also called the Rounded Maplet in other countries, this species is the only representative of the subfamily Cyrestinae that can still be found in Singapore. Another related species, the Wavy Maplet (Chersonesia rahria rahria) is potentially extirpated from Singapore and has not been recorded on the island for at least the past five decades.

The Little Maplet is a forest-dependent butterfly, often found in localised areas in the nature reserves of Singapore. They are rather feeble in flight, but very skittish and takes off to the treetops when alarmed. They have a habit of settling on the undersides of leaves with their wings spread open. The species has a wingspan of about 30-34mm and is the smallest species of the genus Chersonesia.

At times, they are also observed to puddle along damp footpaths and foraging amongst leaf litter. They are also spotted with many other species of butterflies, when the Syzygium trees flower in the nature reserves. Considered a moderately rare species, the Little Maplet is not often encountered but may be seasonal and several individuals may be spotted during certain months of the year.


The Little Maplet is orange brown above with reddish brown bands across both wings. The undersides are a pale orange-yellow and similarly marked as the uppersides. The species has the upperside forewing post-discal band double and the two bands internal to it are wide. This is the main distinguishing ID key to separating it from the other species in the genus.

The eyes of the butterfly are yellow-green and species of the genus have rather prominent pointed palpi. When at rest, the antennae of the Little Maplet are occasionally observed to be held close together rather than splayed. The antennae are black-and-white banded and orange tipped.


The caterpillars of the Little Maplet feed on Ficus punctata (Climbing Fig) and its life history has been successfully recorded in Singapore. Although the caterpillar host plant can be commonly found and widely distributed in Singapore - even in urban parks and gardens, the Little Maplet prefers the shaded forest understorey and remains in the safety of the nature reserves in Singapore.

IUCN Conservation Status in Singapre : Vulnerable
Threat : Loss of habitats and caterpillar host plants 
Conservation measures : Ensuring that the caterpillar host plants in its preferred habitats within localised areas in Singapore's nature reserves continue to be present.
