Leucoma ochripes


Diagnosis.
This is the larger montane species. The forewing apex is produced compared with other Bornean congeners. The labial palps and forelegs are yellowish orange, the former short, not protruding significantly beyond the white scales of the frons. The antennae are slightly paler and browner than the forelegs.

Taxonomic note. The male genitalia are illustrated in the original description of eshanensis and appear very similar to those of ochripes.

Geographical range. N.E. Himalaya, Yunnan, Borneo.

Habitat preference. A male and two possible females have been taken on G. Kinabalu, at 1930m, and at 1050m and 1620m respectively.

Biology. Gardner (1938) and Sevastopulo (1943) described the larva (as Caviria or Caragola ochripes) in India.

The mature larva has a pale orange head. The legs, prolegs, ventral surface and dorsal glands are pale yellow. The upper part of the body is pure white, streaked and speckled with black.

T1 has crimson verrucae, those on other segments being orange or yellow. The paired glands on A1 and A2 have dorsal brushes consisting of a ring of short, thick, pink hair round the black, pale-tipped glandular tubercle. A3 has a dorsal tuft of short, white hair and a minute orange tubercle with a rosette of such hair. Posterior to this there are two pairs of such tubercles with yellow hair on each segment. Gardner also described earlier instars and gave more detail of the distribution of verrucae.

The eggs are laid in single rows on a leaf and are not covered with hair from the abdomen of the mother. The pupa is ivory white, dorsally brown, with
brown patches on the wing cases. Secondary setae on verrucae are conspicuous. The pupa is formed among a few silken threads spun across the hollow of a leaf.

Browne (1968) indicated the larva was polyphagous on dicotyledonous trees, mentioning specifically Sapium (Euphorbiaceae). Gardner (1938) and Sevastopulo (1943) gave Litsea and Phoebe (Lauraceae) as host-plants.
