Subspecies: atlites Linnaeus, 1763
Wingspan of Adult Butterfly: 55-60mm

Physical Description of Adult Butterfly:
On the upperside, the wings are pale greyish buff and distinctly marked with dark brown discal and submarginal lines. Post-discal series of eye-spots, some of which are divided into an outer black half and an inner orange half, are found on both forewing and hindwing. On the underside, the wings are marked as per above but all markings are much paler.

Field Observations of Butterfly Behaviour:
This species is the rarest of the four Pansy species in Singapore. It makes seasonal and localized appearances, and can be found in nature reserves and coastal parks. It flies in the usual gliding manner of the Junonia spp. Under sunny condition, the adults have a habit of opening their wings wide to sunbathe while resting on a perch.
