Biology. Information in Jervis et al. (1988), Kitamura (1989c) and Sahragard et al. (1991) (as Dicondylus indianus Olmi).
Natural enemies. Encyrtidae (Guerrieri & Viggiani, 2005): Cheiloneurus exitiosus (R. Perkins). In Viet Nam this species can be parasitized by Encyrtidae. M. Olmi reared seven male specimens of an unidentified Encyrtid from a cocoon on rice collected in the Southern Regional Plant Protection Center. In Thailand G. flavifemur can be parasitized by Trichomalus apanteloctena (Crawford) (Pteromalidae) (Olmi, 2000a).
Distribution. China (Taiwan, Fujian, Hubei, Guangdong, Guangxi, Guizhou, Yunnan, Hainan, Jiangsu, Zhejiang), India (Karnataka, Orissa, Andhra Pradesh, Tamil Nadu), Philippines (Luzon), Malaysia (Malaya), Viet Nam (Tieng Giang), Australia (Queensland), Japan (Kyushu).
