The dry season forms are pale brown with a few obscure markings. The apex of the fore wing is produced and angular only in the wet season forms. The sexes are similar in appearance.

                    Lemon Pansy. Junonia lemonias

It is a brown butterfly with numerous eye-spots as well as black and lemon-yellow spots and lines on the forewing and hindwing. In the dry season, the markings are reduced and in the wet season, they are more prominent and larger. The colouration on the underside of the forewing is also variable. In the wet season, the markings are distinct and vivid, in the dry season, they are obscure and pale, thus aiding the butterfly in camouflage among dried leaf- litter. The male and female look similar. It has a wingspan of about 45- 60 mm.
