Notes on biology. Species of Bracon are primary ectoparasitoids of Lepidoptera, Coleoptera, and some Diptera and Hymenoptera larvae (Quicke 2015). Several species of Bracon are known to be parasitic of Fergusonina including B. fergusoninus Taylor, Austin & Davies from galls of F. lockharti Tonnoir on E. camaldulensis (Taylor et al. 1996, Taylor et al. 2005) and an undescribed species from galls of F. turneri Taylor on Melaleuca quinquenervia (Cav.) S.T.Blake (Davies et al. 2001, Goolsby et al. 2001). In these studies Bracon was considered to be a primary ectoparasitoid of Fergusonina . However due to its relatively larger size, in this study the species of Bracon reared is likely to be a primary parasitoid of either of the lepidopteran inquilines Ardozyga loxodesma or A. stratifera (Gelechiidae) .
