Junonia almana, the peacock pansy, is a species of nymphalid butterfly found in Cambodia and South Asia. It exists in two distinct adult forms, which differ chiefly in the patterns on the underside of the wings; the dry-season form has few markings, while the wet-season form has additional eyespots and lines. It is listed as Least Concern in the IUCN Red List.
The adult butterfly has a wingspan of 54–62 mm (2.1–2.4 in), and exhibits seasonal polyphenism.
J. almana is found in India, Sri Lanka and South East Asia, and eastwards to China and Japan.
It has a cylindrical body with distinct color bands or patterns, which change as it grows and molts. Pupal After reaching sufficient size, the larva forms a chrysalis. Within this protective casing, peacock pansy undergoes drastic transformation, with tissue breakdown and reorganization.
Junonia almana completes its life cycle in 24.40 ± 1.14 days (eggs 3, larvae, 15 – 16, pupa 5 – 7 days).
The adults will nectar from a variety of flowers but they really seem to enjoy Lantana.
Above, the wings are rich yellowish brown with darker brown edges at both termen and costal margins. On each of the forewings, there are four distinct costal bars, the outermost three of which are filled with darker shadings. There is a prominent ``peacock'' eye-spot in space 2 near the tornal area, and a lesser one in space 5. On each hindwing, a much larger and more prominent eye-spot is featured in spaces 5-6 near the apex. The termens of both fore- and hindwings are marked by two series of marginal striae. Underneath, the wings are duller and the costal bars are filled with paler shadings instead. Compared to those on the upperside, the ocelli are smaller and on the hindwing, there is an additional ocellus in space 2, and the spot in spaces 5-6 appears to be a conjoined pair. Each of the fore- and hindwings has a dark stripe traversing from the costa to the dorsum. The stripes appear to be continuous across the two wings. The stripe on the hindwing is outlined by a broad pale band on the inner edge.

This species is rather common across multiple habitats in Singapore, with ubiquitous presence in open areas in the nature reserves as well as urban and suburban areas. It flies in the usual gliding manner of the Junonia spp. and typically several individuals can be seen together in one location. Under sunny condition, they have a habit of opening their wings wide to sunbathe while resting on a perch.
The eggs of the Peacock Pansy are laid singly on leaves or shoots of the host plant and rather frequently, on plants of other species in the vicinity of the host plant. The greenish egg is somewhat globular in shape but with a blunt top. Eleven to thirteen raised whitish ridges run from the top to the base of the egg. Each egg has a diameter of about 0.75mm.
