This article https://www.landcareresearch.co.nz/discover-our-research/managing-invasive-species/weed-biocontrol/projects-agents/biocontrol-agents/st-johns-wort-beetle shows the difference between Chrysolina quadrigemina and C. hyperici. Are both present in the ACT? @galah681 suggests there are both, but only one is in the CNM list and the other is in iNaturalist.
