Biology.This species were previously reported from a variety of host plants, including Capesaffron, Cassine peragua(Celastraceae)and Cordia caffra(Boraginaceae)( Schedl 1965). New collections were made from Capesaffron. Thin branches of 2–5 cmdiameter were colonized by a male which was joined by either one or two females. Two broods of individual females contained 30 and 38 larvae, respectively.
