Hampson
Hypothripa ruficirra Hampson, 1905, Ann. Mag. nat. Hist. (7), 16:
540.
Characoma ruficirra Hampson; Holloway, 1976: 21.
Diagnosis. See the previous species.
Taxonomic note. G.
casuaria
Wileman & West comb. n. (Philippines) is closely related.
Geographical range. Japan, N.E. Himalaya, Borneo.
Habitat preference. Specimens have been taken mostly from montane forest
from 1000m to 1930m but one was taken in dipterocarp forest at 150m at the foot
of G. Mulu.
Biology. The larva in Japan is stout, a glossy olive-green with pale yellow
speckles. The primary setae are long and set on slightly darker pinacula (Sugi,
1987). It bores in green nuts of Castanea and Quercus (Fagaceae),
and the tips of young shoots of Lithocarpus in the same family (Sugi;
Teramoto, 1996). Mathur (1942) recorded Juglans (Juglandaceae) and
Quercus as host-plants in India, the larva feeding on the green fruits of
the former and defoliating the latter.
