Encyclopedia
The Common Lineblue Prosotas nora is a species of lycaenid
butterfly found in Asia
.
Male Upperside: purplish-brown or purplish with a dark tint, some specimens brown with, a very slight purplish sheen seen only in certain lights. Fore and hind wings : nearly uniform, both with slender black anticiliary lines, the hind wing in addition with the costal and dorsal margins paler; in most specimens with a sub-terminal black spot in interspace 2, sometimes seen only by transparency from the underside; tail black tipped with white. Underside: brown, hoary, brownish or pale dull brown. Forewing: a subbasal pair of transverse white strigae, a shorter pair along the discocellulars and a discal pair ; these strigae all narrowly edged on the inner sides of each pair with fuscous which gives the appearance of transverse bands somewhat darker than the ground-colour; the subbasal pair extend from vein 1 to vein 12, the discocellular pair from upper to lower apex of cell and the discal pair are very irregular and dislocated at each vein, the whole having the appearance of a dark sinuous band; terminal markings often very faint and ill-defined or again fairly prominent and consisting of a double subterminal series of transversely linear, sometimes lunular, dark spots, with edgings paler than the ground-colour; lastly, an anticiliary dark line. Hind wing: with transverse pairs of white, inwardly fuscous-edged strigae similar to those on the fore wing, but even more irregular and broken; the subbasal pair extended from costa to vein 1, below which the dorsal area is whitish, the discocellular pair extend from the costa and posteriorly coalesce with the discal pair which are as irregular and dislocated as in the fore wing; terminal markings similar to those on the fore wing, but the double subterminal series of dark spots more lunular and a prominent round black subterminal spot crowned with ochraceous in interspace 2. Antenna, head, thorax and abdomen dark brown; the shafts of the antennas speckled with white; beneath: the palpi fringed with black, thorax dark greyish-brown, abdomen white.
Female upperside: brownish purple, sometimes fuscous. Fore and hind wings : as in the male with anticiliary dark lines, but differ as follows: Fore wing: an iridescent bluish sheen from base outwards to disc; hind wing; a slender more or less prominent white line edging the anticiliary black line on the inner side, a sub terminal geminate double black spot in interspace 1 and a similar larger single spot in interspace 2. Underside: ground-colour paler and brighter than in the male, the-markings similar but more neatly and generally more clearly defined; both fore and hindwings in most of the specimens have a white terminal line before the anticiliary dark line. Antennae, head, thorax and abdomen much as in the male.
