This native Australian species, which attacks Eucalyptus, has been accidentally introduced to practically every other region in the world where these trees are grown. While not a significant pest in Australia, it is damaging overseas. Consequently there is a vast literature on its control.
Phoracantha semipunctata is listed in the following regions:
Canberra & Southern Tablelands | Albury, Wodonga | South West Western Australia
