Diagnosis
Confusion with Psilogramma menephron is possible, but the pale discal spot is very prominent, linked to the costa by a strong, oblique dark brown bar that is lacking in menephron.
Taxonomic Notes
Bornean material is referable to ssp. thielei Huwe.
Geographical range
Throughout the Indo-Australian tropics to New Guinea and Queensland.
Habitat preference
All specimens have been taken in the lowlands.
The species is infrequent.
Biology
Dupont & Roepke (1941) described and illustrated the larva in Java.
It is green with a dorsal yellow patch on T1 and broad, oblique, white stripes on the abdominal segments that tend to run into a paler dorsal stripe.
The anterior oblique stripes are more pronounced and extensive in early instars.
Recorded host-plants (Bell & Scott, 1937; Moulds, 1984) are: Annona, Melodorum (Annonaceae); Kigelia, Spathodea (Bignoniaceae).
