Pareronia valeria
Pareronia valeria, the common wanderer or Malayan wanderer, is a medium-sized butterfly of the family Pieridae, that is, the yellows and whites, and is found in India and Southeast Asia. The butterfly found in India is sometimes considered as a separate species, Pareronia hippia. Description Male upperside: ground colour a clear pale blue of a much deeper tint than in P. avatar, Moore; all the veins defined with black. Forewing: costa broadly, apex and terminal margin very broadly black, this black on the termen narrowed towards the tornus, and traversed by a transverse subterminal series of bluish-white spots that are variable in number; the spot in interspace 3 shifted inwards; sometimes the posterior two spots of the series are all but joined onto the streaks of the ground colour between the veins. Hindwing: dorsal and costal margins broadly whitish: terminal margin broadly black, especially at apex, the black area covered, except at the tornus, with specialised opaque-looking scales. Underside: paler blue, the terminal margins of the wings obscurely fuscous, traversed by a subterminal, very indistinct, transverse series of whitish lunulated spots. Forewing: the veins more or less broadly bordered with black, this edging broadened towards the termen; apex broadly, terminal margin decreasingly to the tornus, suffused with a somewhat obscure pearly-while lustre. Hindwing: the subcostal vein and veins 6, 7, and 8 broadly, the rest of the veins very narrowly edged with black; a very fine black line in interspace 1. Cilia of both forewings and hindwings very narrow and white. Antennae black, head, thorax and abdomen fuscous, the thorax clothed with long bluish hairs; beneath: the palpi, thorax and abdomen pale silvery bluish-white. Female: First form. Upperside: black; the markings bluish white. Forewing: cell with two streaks, the anterior one from the extreme base, the posterior one from the end of the basal third, but extending beyond the anterior streak; below and beyond the cell is a series of streaks in the interspaces; the streaks very irregular in length, that in interspace 1 the longest, angulated anteriorly and divided longitudinally from near its base, the streak in interspace 3 short and broad forming an elongate spot, those in the anterior interspaces more or less obliquely placed; beyond these streaks follows a subterminal transverse series of spots, of which the spot in interspace 3 is shifted inwards and those opposite the apex curved backwards. Hindwing: costa and dorsum broadly white; cell and the interspaces beyond with a series of streaks and sub-terminal spots, more or less as in the forewing but more regular; the streak in cell and interspace 1 divided longitudinally, the subterminal series of spots evenly curved. Underside: similar to the upperside, but the ground colour dull, dusky and diffuse, the markings broader but less clearly defined; the apical area on the forewing obscured by a powdering of whitish scales. Antenna, head, thorax and abdomen much as in the male but darker. Second form. Very like the first, the markings both on the upper and under sides similar,
