The
Swordtails are remarkable for the very long, slender and tapering tail
on the hindwing. They are forest butterflies and are very swift on the
wing, with an erratic flight. They are often mistaken for a white Pierid
butterfly, as the tails are usually not seen during flight.
The male Five Bar Swordtail featured
here was photographed feeding at a muddy seepage in the nature reserves.
The species is creamy white above, with a series of black transverse stripes
in the costal area of the forewing. On the underside, the basal half of
the hindwing is green, with black stripes and spots. The butterfly has
a wingspan of 40 - 45 mm.
This species is the only representative
of the genus Pathysa in Singapore. It is credited with being one
of the few butterflies in the region to bear a local name - itamputi,
from
the Malay words "hitam", meaning black, and "putih", meaning white. |
