The Common Wanderer or Malayan Wanderer (''Pareronia valeria'') is a medium-sized butterfly of the family Pieridae, that is, the Yellows and Whites, and is found in India and Southeast Asia. ==Description== :''See glossary for terms used'' Male upperside: ground-colour a clear pale blue of a much deeper tint than in ''P. avatar'', Moore; all the veins defined with black. Fore wing: 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 groundcolour between the veins. Hind wing: 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. Fore wing: 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. Hind wing: 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 fore and hind wings 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. Upper-side: black; the markings bluish white. Fore wing: cell with two streaks, the anterior one from the extreme base, the posterior one from the end of the basal third, but extending beyond tho anterior streak; below and beyond the cell is a series of streaks in the interspaces; tho 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. Hind wing: 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 fore wing 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 fore wing 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, but the ground-colour on the upperside of the hind wing at base of interspace 1 a, over the whole of interspace 1, area of cell and at base of interspace 2 suffused with bright yellow. On the underside the same areas are dull ochraceous. The extent of the bright yellow colour on the upper-side and of the dull ochraceous tint on the underside is variable, in some specimens more restricted, in others it spreads further towards the costa. The common form of female mimics glassy tiger to avoid predation. The ''philomela'' form is rare and identified by yellow coloration at the base of the wings. this form is reported more in North-East India.〔Bingham, C. T. (1907). ''Fauna of British India. Butterflies. Vol. 2.''〕 According to Wynter-Blyth this form mimics ''Danais aspasia'', which is not found west of Myanmar. He rejects the assumption that the wagtail carries the eggs of ''D. aspasia'' to India. It seems that in bygone era the ''D. aspasia'' might have been found in India in the past along with the Common Wanderer and later eliminated. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pareronia valeria」の詳細全文を読む スポンサード リンク
