Hemonia rotundata Snellen 
Pitane rotundata Snellen, 1879, Tijdschr. Ent., 22: 90.

Hemonia rotundata
(x 1.63)

See the previous species.

Taxonomic note. The Bornean females referred to in the original description of H. pallida Hampson (New Guinea, Australia) are referrable to rotundata.

Geographical range. Java, Bali, Borneo, Peninsular Malaysia, Philippines, Sulawesi.

Habitat preference. Specimens have been taken infrequently mainly in the lowlands in both primary and secondary forest. The highest record is from 1000m on G. Mulu.

Biology. Piepers & Snellen (1904) noted the larva to be covered in pale grey hairs which were incorporated in a transparent cocoon. The pupa was formed vertically within the cocoon, itself formed on the side of a box; the adult emerged a week after pupation. The larva was full-grown when found, so the diet was not noted. Unpublished FRIM and IIE records note the larva on the leaves of Acacia mangium (Leguminosae), but possibly it was grazing on lower plants growing on these.
