Hosts. Hemiptera : Aleyrodidae , Coccidae , Diaspididae ; Lepidoptera : Noctuidae , Pyralidae , Tortricidae , Yponomeutidae (for detailed host species see Noyes, 2016).

Distribution. Nearly cosmopolitan ( Noyes 2016). China (Heilongjiang, Inner Mongolia, Jilin, Liaoning, Shaanxi, Shandong, Sichuan [new records], Guangdong, Taiwan, Yunnan).

Comments. This is a widespread species, with great variation in colour of the female metasoma, from largely pale ( Fig. 24 ) (only petiole, base and sides of T1 brown), to partly brown ( Fig. 25 ) (petiole, base of T1, sides of TI– T6 and T5 brown) to T6 largely brown ( Fig. 26 ) (T1 posteriorly to T3 anteriorly and apex of T7 yellow). Specimens with the metasoma largely brown usually have dark brown patches on a brown mid lobe and scutellum ( Fig. 27 ), occasionally both females and males with two distinct dark patches on a yellow scutellum ( Figs. 28, 29 ).

Antenna yellow with radicle brown, scape yellow to brown, and apical flagellomere infuscate. Petiole smooth or faintly sculptured ( Fig. 30 ). Legs of male yellow with fore and hind coxae brown, mid coxae yellow to brown, hind femora yellow to brown. Genitalia 0.83–0.96× as long as hind tibia.
