Host plant notes

I have reared adults of M. vittata from billets cut from dead Acacia branches: one individual from A. retinodes near Rockleigh, and one from a cultivated shrub of Notable Wattle Acacia notabilis at Urrbrae. Turner 2001a reported the first breeding record of this species, with extraction of specimens from a dead shrub of A. chalkeri in NSW. Given its wide distribution and range of adult hosts, it is likely to breed in Golden Wattle A. pycnantha and a range of other Acacia species also.
