Species of nymphalid butterfly found in South Asia From Wikipedia, the free encyclopedia
Junonia almana, the peacock pansy,[2][3] is a species of nymphalid butterfly found in Cambodia and South Asia.[2][3] 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.[4]

The adult butterfly has a wingspan of 54–62 mm (2.1–2.4 in),[1] and exhibits seasonal polyphenism.
"Upperside rich orange-yellow. Fore wing with a pale dusky and a much darker short transverse bar with lateral jet-black marginal lines across cell, another somewhat similar bar defining the discocellulars; costal margin, an inner and an outer subterminal line, and a terminal line dusky black; a large minutely white-centred ocellus with an inner slender and outer black ring on disc in interspace 2; two similar but smaller geminate subapical ocelli with an obscure pale spot above them and a short oblique bar connecting them to the black on the costa. Hind wing: a small minutely white-centred and very slenderly black-ringed discal ocellus in interspace 2, with a very much larger pale yellow and black-ringed ocellus above it spreading over interspaces 4, 5 and 6, the centre of this ocellus inwardly brownish orange, outwardly bluish black, with two minute white spots in vertical order between the two colours; finally postdiscal subterminal and terminal black sinuous lines.[1]
"Underside ochraceous brown, very variable. In most specimens the cell of the fore wing is crossed by three dark sinuous bands, the outermost along the discocellulars; these are very faint in some; both fore and hind wings crossed by a basal and a discal pale sinuous line, the latter margined outwardly by a dark shade, which is traversed by an obscure somewhat obsolescent row of dark spots, and outwardly bounded by a subterminal sinuous line, the dark shade in many cases spreading on the fore wing to the terminal edge of the wing; on the hind wing the subterminal line meets the discal in an acute angle at the tornus. Antennae dark brown; head, thorax and abdomen more or less orange-brown; paler beneath."[1][5]

"Upperside similar, the black markings deeper in colour and heavier, the subterminal and terminal lines more clearly defined.
"Underside pale ochraceous. Fore wing: cell crossed by live short sinuous dark brown lines, a similar line on the discocellulars and another beyond it, both bent inwards at an angle and continued to the dorsum, the space between them forming a discal broad fascia, which pales to whitish posteriorly; the postdiscal ocelli, subterminal and terminal lines as on the upperside but paler. Hind wing: a slender transverse subbasal dark line, a discal whitish straight fascia in continuation of the one on the fore wing; the postdiscal ocelli, the subterminal and terminal lines much as on the upperside but paler; the anterior ocellus with a double iris and centre. Antennae dark brown; head, thorax and abdomen slightly darker than in the dry-season form."[1]
J. almana is found in India, Sri Lanka and South East Asia, and eastwards to China and Japan.[1][2][3]
The caterpillars of Junonia almana feed on a variety of plants, including Hygrophila auriculata, Phyla nodiflora and species in the genera Acanthus, Barleria and Gloxinia.[6]
"Cylindrical. Head blackish, slightly hairy. Body pale ochreous-brown, with a dorsal, subdorsal and lateral blackish line, and a row of small-ringed spots below the latter; second segment anteriorly with a transverse reddish stripe; second, third and fourth segments posteriorly with a transverse blackish stripe; second to last segment armed with a dorsal, subdorsal, and two lateral rows of short, fine-branched spines." (Frederic Moore quoted by C. T. Bingham)[1]
"Rather short and thick; head and thorax broad, headpiece pointed beneath; thorax and abdomen dorsally with short tubercular points; colour brownish-ochraceous." (Frederic Moore quoted by C. T. Bingham)[1]
