Commonly known as Common Grass Yellow, this butterfly is the commonest butterfly in the eastern tropics, ranging from Sri Lanka and India to Indo-China, Thailand, Peninsular Malaysia, Singapore, Sumatra, Java, Borneo and Palawan. It inhabits inland forests at low to moderate elevations. It is most abundant on the plains but can also be found on the mountains up to 1,500 m (Corbet & Pendelbury, 1978).

The Common Grass Yellow has a wingspan of about 2.2 cm long. It can easile be identified by its bright yellow wings with black bordering forewings and blackish-brown marking hindwings on the upperside. The underside of the wings are also yellow with undivided chocolate patch and typically two small cell spots on its forewing (Kirton, 2014). The female is usually larger, paler and more broadly black-bordered than the male (Corbet & Pendelbury, 1978).
