The caterpillar leaves its foodplant, to pupate on a stem of an adjacent plant, to which it attaches itself by its tail and a girdle.
The adult butterfly on top is yellow with black borders. There is a double indentation in the border about halfway along the margin of each forewing. The adult butterfly is similar to that of Eurema hecabe, but has broader black borders to the hindwings.
The undersides are similar to the upper surfaces, except for some obscure brown markings. These markings are more evident in the dry season forms. The wingspan is about 3.5 cms.

The species occurs as about 20 races throughout south-east Asia, including:
