Pheosia

Neopheosia
fasciata Moore; Kiriakoff 1968: 183.
Diagnosis. The forewing pattern of black and brown streaks on pale yellow is
unmistakable.
Taxonomic note. Specimens from Sundaland have the valves of the male genitalia deeper
and the gnathal processes more robust than Himalayan ones. Buru males have the
ventral process at the base of the uncus roughly half the length of the gnathal
processes rather than equal in length.
Geographical range. Himalaya, Taiwan, Sundaland, Buru.
Habitat preference. The species appears to be infrequent in a range of
lowland forest types, and has been taken as high as 1618 m on Bukit Retak in
Brunei.
Biology. Barlow (1982) gave a brief description of the larva, here augmented by
study of a blown larva in the BMNH. The larva is cylindrical and unmodified
apart from a prominent slender dorsal horn at the anterior margin of the first
abdominal segment. The ground colour is pale green. The head is streaked with
dark red and the body has a dorsal series of dark red quadrate marks, narrower
but darker and more intense over the thorax, broader, diffuse, striate over the
first three abdominal segments, and largest from the fourth abdominal segment
backwards. The sides of the thoracic segments are immaculate but the abdominal
flanks are ornamented with numerous fine, oblique, red striae commencing from
the quadrate marks and running back down the flanks.
The host-plant in India was given by Sevastopulo (1940) as 'cherry'.
