Distribution

Recorded in the study region from Bangladesh, China (Fujian, Yunnan), India (Andaman Is, Jharkhand, Karnataka, Kerala, Madhya Pradesh, Odisha, Tamil Nadu, Uttarakhand, West Bengal), Nepal, Taiwan, Thailand, Vietnam. It also occurs in Sri Lanka and through Malaysia and Indonesia, to the Philippines and New Guinea. Presumably imported to and established in East Africa (Tanzania, Zambia) and the Seychelles. Introduced and established in the USA (Okins and Thomas 2010, Gomez et al. 2018a).

Host plants

polyphagous (Browne 1961b, Schedl 1963a)

Remarks

Kalshoven (1959b) gives some details of brood sizes at different stages of development of the brood chamber. The species attacks plantation trees, but the attacks are secondary on stressed or dying host trees and not primary on healthy trees (Maiti and Saha 2004).
