Prey / associated habitat. All known hosts are aphids and include Macrosiphoniella artemisiae (Boyer de Fonscolombe), Rhopalosiphum maidis (Fitch), Taoia indica (Ghosh & Raychaudhuri), and Tuberculatus indicus Ghosh; found on Alnus nitida and Juglans regia; occasionally found in oak (Quercus serrata) farms (Singh and Singh, 1985). Devi (1989) recorded it as a predator of aphids infesting oak in Nagaland, particularly Eutrichosiphum dubium (van der Goot) (as Holotrichosiphon dubius) on Quercus dealbata and Cervaphis quercus Takahashi on Quercus serrata. Seasonal occurrence. Active during May – July, October – December in north and northeastern India (Singh & Singh 1985; Devi 1989).
