Description

From Bingham, C. T. (1907) The Fauna of British India, Including Ceylon and Burma. Butterflies. Vol 2

• Unpublished MS of de Niceville gives it the common name of "wandering snowflake"
• Upperside: white; base of wings very slightly powdered with minute black scales. Forewing: costa speckled obscurely with black; apex black, the inner margin of this inwardly angulate; a very large somewhat pear-shaped post-discal spot also black. Hindwing white, uniform; in most specimens an obscure, extremely slender, terminal black line.

Underside: white, coastal margin and apex of forewing broadly, and the whole surface of the hindwing irrorated with transverse, very slender, greenish strigae and minute dots; these on the hindwing have a tendency to form subbasal, medial and discal obliquely transverse obscure bands; forewing: the postdiscal black spot as on the upperside; terminal margins of both fore and hind wings with minute black, short, transverse slender lines at the apices of the veins, that have a tendency to coalesce and form a terminal continuous line as on the upperside. Antennae dark brown spotted with white, head slightly brownish, thorax and abdomen white. Female: similar, the black markings on the upperside of the forewing on the whole slightly broader, but not invariably so.

• Wingspan: 25–53 mm
• Habitat: The lower ranges of the Himalayas from Mussoorie to Sikkim; Central, Western and Southern India, but not in the desert-tracts; Ceylon; Assam; Burma and Tenasserim; extending to China and the Malayan region.

• Larva: Green with a pale glaucous tinge about the bases of the legs and slightly hairy. Feeds on capers. Capparis zeylanica has been noted as a food plant.
• Pupa: Sometimes green, but oftener of a delicate pink shade. Both the larva and pupa are very like those Terias hecabe, but more delicately formed. (Davidson, Bell and Aitken quoted in Bingham)
