genus Parthenos comprises of 3 species,

Papua New Guinea, while sylvia in
comparison has an extremely wide distribution being found in
Sri Lanka, India, Myanmar, Thailand, Malaysia, Borneo, Sumatra, the
Philippines, Sulawesi, Java, Bali, Papua New Guinea and Irian Jaya.
This species is found in primary rainforest,
usually in the vicinity of rivers, at elevations between sea level
and about 300 metres.
The larva is brown,
speckled with white dots, and has broad greenish dorsal and lateral
stripes. Each segment bears 4 multi-branched spines, purplish brown
at the base and red on the outer half. The larval foodplants include
( Passifloraceae )
( Menispermaceae ).
occurs in 2 forms, either pale green or dark olive. It is rather
plain in appearance, without protuberances, and is suspended by the
cremaster from beneath a leaf.
The Clipper is a
powerful and fast flying butterfly. The flight consists of short
periods of gliding, alternating every few seconds with shallow but
rapid flickering wing beats.
On the Kinabatangan
river in Borneo I have observed hundreds of these magnificent
butterflies circling and gliding around tree tops along several
kilometres of the river edge.
Both sexes commonly
nectar at Lantana and other flowers.
Males will also settle on the ground to imbibe moisture. If
disturbed they fly up immediately, circle around at a height of
about 3 metres, and then resettle nearby.
