Lascars are similar in pattern and wing shape to the
Neptis Sailors, but the stripes and
bands on the upperside wings are orange instead of white.
are about 15 species in the genus Pantoporia,
of which 5 are found in India. The remainder are distributed
variously across tropical Asia and Australia.
Pantoporia hordonia is by far the
commonest and most widespread member of the genus, being found in
India, Sri Lanka, Bhutan, Myanmar, Laos, Cambodia, Vietnam, south
China, Taiwan, the Philippines, Malaysia, Sumatra, Borneo, Sulawesi,
Java and Lombok.
butterfly is found in disturbed areas of primary rainforest,
including clearings, glades, logging roads and forest-edge habitats.
It occurs at elevations between sea level and about 500 metres.
egg is pale green and covered in a network of hexagonal ridges from
which arise numerous very short spikes. It is laid singly on the
underside of leaves of the foodplants.
The caterpillar is
pale olive green, with a large straw-coloured 'saddle' which tapers
towards the anal segment, and extends to below the spiracles along
the first 4 abdominal segments. Along the sides, within the saddle
area are 4 diagonal dark olive stripes. The head is smooth, and
olive in colour. The caterpillar feeds on withered leaves of
Pithecellobium and possibly other Mimosaceae.
The chrysalis is
pale brown with blackish markings, dark green wing cases, and a
group of white circular spots on the thorax. It is suspended by the
cremaster from a leaf or twig.
adults have a sailing flight similar to that of
Neptis, but not as graceful. They are
usually seen singly, most often along narrow trails or small glades
in heavily forested areas.
have occasionally observed males mud-puddling but more commonly they
are seen basking on foliage or among leaf litter on the forest
floor. I have not seen either sex nectaring at flowers.
