preference. All Bornean records are from G. Kinabalu, three from 1050m in

Biology.
The larva was described by Sevastopulo (1939b) and Gardner (1941, 1947), and
illustrated by Sugi (1987). The prolegs on A3 are strongly reduced, and those of
A4 moderately so. The larva is mostly pale green, but the top of the head and
dorsolateral longitudinal lines are pale yellow. There are also fine broken
white lines dorsally and laterally, though Sevastopulo referred to darker dorsal
and lateral stripes. The primary setae arise from bluish black dots that are
ringed paler.
The host
plant is usually Rubus (Rosaceae), but the larva has also been recorded from Rosa
in
the same family and from Lantana in the Verbenaceae (Robinson et
al.,
2001).
Bänziger
(1982) recorded the adult as a fruit piercer in Thailand.
