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.
