ADULT BIOLOGY

At Yinggeling, Hainan, adults were taken at light near a small village surrounded by forest fragments, and cassava and rubber plantations (Roger Kendrick, pers. comm. 2006)


FLIGHT-TIME

China: 5.iii (Simao/Pu'er); v (Songzhishanding); vi (Dianchang Shan; Simao/Pu'er); vii (Hengduan Shan); 25.viii (Hainan); ix (Ailao Shan; Lushui); ix (Fuli Shan).


EARLY STAGES

OVUM: Unknown.

LARVA: Unknown.

PUPA: Unknown.

Larval hostplants. Unknown.


PARASITOIDS

Unknown.


LOCAL DISTRIBUTION

China: Yunnan (Ailao Shan; Dianchang Shan; Fuli Shan; Hengduan Shan, 2000-2500m; Changning Co., Songzhishanding, 2800m; Lushui, 850m; Simao/Pu'er; Gaoligong Shan); Guangxi; Hainan (Yinggeling, 360m (1901'37" N, 10924'00" E)).


GLOBAL DISTRIBUTION

Found from southern China (Yunnan, Guangxi, Hainan Island and, maybe, eastern Xizang/Tibet), northern Thailand, Laos, Vietnam to northern Sumatra, Indonesia (Diehl, [1982]).

It should be noted that the individuals of Callambulyx tatarinovii tatarinovii Bremer & Grey, 1853 recorded from eastern Xizang/Tibet (Mutu, Namjagbarwa region, 850m; Nyingchi, 3070m) may turn out be a northern population of Callambulyx diehli. This requires further study.

[Callambulyx poecilus is confined to northern Pakistan (Murree Hills, Punjab) (Rafi et al., 2014), Nepal and northern India (Sikkim and Meghalaya) (Brechlin & Kitching, 2012).]
