Thinopteryx crocopterata

This and the next species are very similar in facies, crocopterata being slightly larger with the wings less heavily irrorated with grey such that the pale orange ground colour is more evident. The forewing fasciae are more prominent, the antemedial more oblique in crocopterata, but nebulosa has a conspicuous yellow patch just basal to the postmedial.

Taxonomic notes. The species occurs in a number of races, such as coreae Wehrli from Korea and erythrosticta Wehrli from Yunnan, not listed above. A related species, praetoraria Felder, occurs in Sulawesi and the Philippines. The Sundanian race is padanga Swinhoe.

Geographical range. India to Korea, Japan and Sundaland.

Habitat preference. Single males were taken in hill dipterocarp forest at 500m and lower montane forest at 1000m on G. Mulu, and 1465m on Bukit Retak.

Biology. The larva was described by Sevastopulo (1947) and illustrated by Sugi (1987). The head is pale buff, slightly indented above. The body is rich reddish brown, apart from the pale buff oblique zone associated with the prolegs mentioned in the tribal description, and the venter which is pale buff grading greenish buff posteriorly. T3 is slightly swollen laterally, Al has a quadrate dorsal spot, and A2-7 each have two pairs of subdorsal black specks.

The pupa occurs in a cell formed by spinning together a leaf. It is elongate, dark purple brown with dark green wing cases. The cremaster is stoutly triangular, ending in two outcurved spines with a number of shorter, hooked spines on either side.

The host-plant was Vitis (Vitaceae); Sato & Nakajima (1975) and Sugi (1987) recorded Ampelopsis in the same family as well as Vitis.
