Orudiza protheclaria

The unusual wing shape and lineated grey facies are unmistakable. 

Geographical range.
Oriental tropics to Sulawesi.

Habitat preference. The species is uncommon, all recent material being taken in lowland alluvial forest regenerating on abandoned farmland near Long Melinau during the Mulu survey.

Biology. Bell (MS) observed the biology in S. India. The larva is fusiform, the head heart-shaped, but rather square. The colour is green, with thick dorsal, and dorsolateral to spiracular, longitudinal white bands. The tubercles of the setae are black, sometimes tinged violet. The anterior hairs of T1 are yellow. The pupa is stout, boat-shaped, the cremaster triangular with a stout shaft bifid at the extremity.

The larvae live on the undersides of leaves, stretched out, though with the thoracic segments contracted. They fall to the ground on a silken thread when disturbed. Pupation is in a slight silken cocoon with particles, either near the ground or in a rolled leaf.

The host-plants are Bajanella and other Bignoniaceae.
