Hyposidra incomptaria

This is the largest of the genus, a variable species, irregularly variegated with rich brown and blackish brown, with paler yellower zones in some specimens towards the forewing margin and hindwing dorsum. The hindwing margin is angled centrally. The female is larger, the margins of the wings more crenulate.

Taxonomic notes. A complex of species occurs in the Australasian tropics. Only incomptaria has a pair of enlarged, slender, club-like setae arising from the tegumen. Only synonyms established by dissection are listed. The following are distinct, but related taxa: H. apicifulva Warren (New Guinea); H. nigricosta Warren (N. Moluccas); H. plagosa Rothschild (New Guinea); H. castaneorufa Rothschild (New Guinea).

Geographical range. Aru, New Guinea to Solomons, Queensland, Moluccas, Sulawesi, Philippines, Borneo, Sumatra, Peninsular Malaysia (FRIM collection).

Habitat preference. Frequent in lowland forest, the species showed some preference for wet kerangas on river terraces during the Mulu survey.

Biology. Bigger (1988) studied the life history in the Solomons. In early instars the larva is black with raised white lateral spots on the abdomen. In later instars it becomes paler, finally light brown, mottled longitudinally, irregularly with darker brown. The white spots become pale cream and are no longer raised, but there are two raised black spots dorsally on A8.

Host-plants recorded were Calophyllum (Guttiferae) Campnosperma (Anacardiaceae), Eucalyptus (Myrtaceae), Merremia (Convolvulaceae) and Terminalia (Combretaceae).
