Berta
annulifera Warren
Berta annulifera Warren, 1861, Novit. zool., 3:107.
Diagnosis. One of the smaller species in the genus, annulifera is
darker green with the white fasciae fine, entire, extremely irregular in their
course. The discal spots consist of small white rings. The male eighth sternite
is bidigitate, rugose. The valve of the genitalia is only weakly modified, and
there is a conspicuously digitate saccus.
Geographical range. India, Sundaland, New Guinea, Bismarcks.
Habitat
preference. The species is infrequent in
lowland forest and has also been taken at 1000m in lower montane forest.
Biology. Bell (MS) described the larva as excessively long and thin, with a
deeply bifid head. It is brown, mottled, with several paler longitudinal lines.
The larva rests on the
edge of a leaf in a looped posture. The pupa sticks out rigidly from the leaf
edge also.
The host-plant was given
as 'goting', but it has not been possible to locate its botanical name.
