There are 10 species in the genus Ixias,
all of which are Oriental in distribution. Males have orange wing
tips and broad dark brown margins, on either a yellow or white
ground colour, depending on the species. Females are similar but
have more extensive dark markings, and in some species e.g.
paluensis they lack the orange patches. The underside of the
wings in both sexes of all species is yellow, with a band of dark
spots. The latter are much more pronounced in the wet season forms.
Ixias species are endemic to islands in
south-east Asia e.g. kuehni on Wetar,
flavipennis on Sumatra,
paluensis on Sulawesi, and vollenhovii
commonest and most widespread member of the genus. It is distributed
from Pakistan to Taiwan, Malaysia, Borneo and the Philippines.

Early in the morning
and late in the afternoon the adults often bask on foliage, with the
wings half open or fully outspread. If disturbed they react by
flying into long grasses or up into trees. During the heat of the
day males imbibe moisture from damp ground, and both sexes nectar
from a wide range of herbaceous flowers.
