Ambulyx canescens
(.65 natural size)


Diagnosis.
Both this and the next species differ from Bornean congeners in having a pair of ocellate marks subapically on the abdomen rather than a narrow dorsal line, more than two subbasal patches on the forewing, definite discal spots, and hindwings concolorous with the forewing. A. canescens is a more greyish species with stronger subbasal markings on the forewing and a stronger green edging to the thorax; there are distinctive pale patches on the hindwing.

Geographical range. S.E. Asia, Sundaland; Philippines.

Habitat preference. Harman (1981) recorded the species generally in Brunei. On the Kinabalu and Mulu surveys it was only taken above 1500m, the highest record being from 2600m.

Biology. The species has been reared from Shorea lepidota (Dipterocarpaceae) at FRIM (Forest Research Institute of Malaysia).
