Asta quadrilinea

Diagnosis. This and the next species have elongate grey brown forewings with a mauvish sheen and four oblique, parallel darker brown fasciae, with dark brown reniform and orbicular dots flanking the second one from the base. The forweing underside is concolorous with the hindwing in quadrilinea.

Taxonomic note. The valves of Bornean males differ from those of males from New Guinea in becoming distinctly broader towards the rounded apex rather than parallel-sided with a slight taper over the distal third. As the next species also has the latter valve shape, it is probably best to treat all three taxa as distinct. New Guinea, Queensland and Solomons material with a grey forewing underside is referable to A. completa Rothschild stat. & comb. n..

Geographical range. Borneo, Peninsular Malaysia, Thailand, Indian Subregion, Philippines, Sulawesi.

Habitat preference. The species has been recorded infrequently in forested localities from the lowlands to 2600m.

Biology. Bell (MS) described the larva. The prolegs on A3 are lacking, those on A4 are reduced. The head is dull yellow with a black surround. The body is a uniform dull watery green, yellowish on segmental margins when these are compressed.

The larva lives beneath the tender leaves that it prefers, and rests stretched out, sometimes on the petioles. Pupation is on the ground in a loose cell of silk incorporating detritus. The pupa does not have a powdery bloom.

The host plant recorded by Bell was
Alseodaphne, and Robinson et al. (2001) noted Cinnamomum, both in the Lauraceae.
