Hosts. Lophopidae ( Guglielmino & Olmi, 1997) : in India: Pyrilla aberrans (Kirby) ( Kurian, 1954a) ; Pyrilla perpusilla (Walker) ( Kurian, 1954a; Rahman & Nath, 1940; Subba Rao, 1957; Asre et al., 1983; Dhaliwal & Bains, 1983); Pyrilla pusana Distant ( Kurian, 1954a) .

Biology. Notes in Rahman & Nath (1940) and Subba Rao (1957); according to Subba Rao (1957) the species is usually parthenogenetic (arrhenotokous parthenogenesis); in India, Punjab, the species overwinters as pupa in the cocoon.

Natural enemies. In India, Punjab, the species is parasitized by the following Encyrtidae : Cheiloneurus sp. ( Rahman & Nath, 1940) and Cheiloneurus quadricolor ( Girault, 1915) ( Mani, 1939; Subba Rao, 1957). However, according to Anis & Hayat (2002) the above quotation of C. quadricolor may be considered doubtfull, because the authors could not check the original material on which the study of Subba Rao was based. According to Anis & Hayat (2002) in fact, in India there is a species of Cheiloneurus very similar to C. quadricolor : C. yasumatsui Trjapitzin, 1971 . According to Anis & Hayat (2002), it is possible that Mani and Subba Rao examined specimens of C. yasumatsui . C. quadricolor is in fact an Australian species and the quotation of Mani and Subba Rao is the only quotation in India. However, according to Guerrieri & Viggiani (2005), C. quadricolor and C. yasumatsui are synonyms and C. quadricolor gains priority over C. yasumatsui .

Distribution. China (Guangdong, Yunnan, Taiwan), Sri Lanka (Matale, Moneragala, Kandy, Vavunyia, Hambantota), India (Bengal, Bihar, Delhi, Haryana, Karnataka, Kerala, Punjab, Tamil Nadu), Indonesia (Sulawesi), Japan (Okinawa), Laos (Attapeu), Malaysia (Sabah), Nepal (Kapilvaslu), Pakistan (Punjab), Philippines (Negros), Thailand (Chiang Mai, Kanchanaburi).
