a pest of "Lilly Pillys", the susceptible species range is perilous to define with lots of contradictory information available. This could be through misidentification of host species or maybe variations in susceptibility due to environmental factors impacting on susceptibility or presence/absence of predator populations affecting distribution. In my experience and locality S.paniculatum is by far the most commonly susceptible, and occasionally Waterhousea floribunda, S.moorei and some S.australe cultivars of which 'Hunchy" appears most susceptible.
